Well I was able to save alot of $$ on my CF hood purchase which has left me extra money that I can now use on my suspension. Most of you are probably thinking that it has been a long time coming & I would agree with you. At this time I'm only purchasing coil overs & have narrowed it down. I originally wanted Stance GR+3s, but have come to the realization that I can't swing the price unless I wait much longer & continue saving. So I have narrowed it down to 2 coil overs that are still of high quality & adjustablity that I believe will perform well on the track.

What I need from the community is to help me decide by voting on the poll I have attached & posting in this thread any insight you have regarding either of these brands & either of these particular coil over systems. I would love to hear from those who already own either of these systems on their vehicle, especially if it is a GenCoupe that sees the track. Yet if you have owned either of these brands before or know someone that has owned them, your feedback may be helpful as well. I will even accept any input from vendors who have used these particular coil overs themselves on their own vehicles if they can do their best to keep the reponses honest & unbias as possible so that it feels more like I'm being informed & less of a sales pitch.

Contestant #1 is the ARK DTP



Highlights:
- 16-Level Adjustment
- Street & Track Performance Specs
- Pillow Ball Mount
- Camber adjustment
- Mono-tube Shock design
- Adjustable Ride height
- Dust Rubber cover included
- 15 months manufacturer limited Warranty
- Spring Rates: Front = 12kg/mm; Rear= 10Kg/mm


Additional info:
- Dampening adjustment allow you to fine tune the ride to your handling and comfort needs.
- Dampening adjusts compression and rebound simultaneously for ease of adjustment.
- Pillow ball top mounts in the front and rear on some applications allow you to maintain vehicle manufacturer suspension geometry design.
- The pillow ball top mounts also allow you a more direct feel for solid driver response.
- Most applications utilize an adjustable lower mount, which means you adjust height without losing suspension travel like some other coilover designs do.
- With the mounts and most pieces of the coilover being designed for 6061 billet aluminum the kit is lightweight, durable, and rust resistant.
- The steel shock body is electroplated with zinc to resist rust and the elements.
- The valving of each set is matched to the springs installed for unmatched ride quality and reliability.
- Monotube design where oil and gas are separated within the cylinder.
- When compared to twin tube designs the Monotube dissipates heat better, allows finer dampening adjustments, and requires more expensive design process.
- Aeration and cavatation are a lot less common in a Monotube design, which results in a better ride.
- The ARK DT-P Coilover system has been designed with professional road racing in mind offering extremely high value and performance.

Highlights:
• 15-Way Damping Adjustable
• Adjustable Camber Uppermount
• Pillowball Uppermount
• Cold Wound Linear Spring
• Inverted Monotube Shocks
• Dustboot
• Aluminum Collars & Upper Mounts
• Height Adjustable Lower Bracket

Exclusive Features for the Genesis Coupe:
• Isolators on the rear springs to reduce noise
• Special bearing spring seat on front shocks to eliminate noise on turning.
• Rear shocks adjustable from the outside

Im actually considering Eibach's as well since ive had good experience with them in the past. Honestly im no suspension expert though...

My DT-P's have treated me great on the track and during auto-x events Plus your sig says you're already sponsored by ARK so you'll save some coin over the Stance's. If you don't have a vendor for either already I'd love to hook you up!

Edit: The spring rates on the ARK are much more conducive for track use and when you're driving the car on the street you can easily dial down the dampening and enjoy a comfortable ride!

HotLZGT

They are both equal quality and features.
Only difference is in color and spring rate.
Do you like a stiffer spring. ( She Does ) get the ARK.
Do you have a red GC? get the ARK.

Want a lighter spring stiffness for mixed use? ( track & DD )get Stance
Want a different color that goes with red? get Stance

If this doesn't help, use a two headed coin. Works every time.

Coming from a guy that do Stance as a hobby (Wheel fitment, Fender rolling, fitment clearance, stance, lower car, VIP, air bag, wheels and tires), between those 2, i would go with Stance since i got a friend got Stance on his RX7 as Drift setup, its stiff but feel amazing when u on track.

The big questions are:
1. What are u plan for the car? (DD/semi-track/track/drift/autoX)
2. How is the road condition around u?

I personally got Megan on for 2 weeks now (pre-owned Fortune Auto Coilover, Megan LP Coilver, Megan EZ Coilover, K-sport v2 Coilover, Function&Form Coilover and BC Coilover)
I pretty much liked all of them, never really got a let down from those (i do for Ground Control Coilver, Tein Basic) but i never really carefully when i chose Coilover so i guess that help.
Loving my Megan so far, running it at 1/2" left to lower, damper setting at 20 and i take "hard" corner, rub a bit on liner in the back (which no big deal). Car does get rough here in there when the road condition is horrible but the Track was doing the same thing. It handles corner way better and stable.
Megan or BC is pretty considerable too.

Never heard or experience with ARK so cant say anything about it.
Seriously, this is my third Megan Coilover (cheapest was Megan EZ on a 09 Accord Coupe) and they r the cheapest Coil there is with pretty good DD feel and fun here and there. Just dont think that they meant for Tracking.

I really like my Stance coilovers. I really don't think you can go wrong with either company. I would go with whatever I could get the best deal on.

To answer giaolong's question big questions:
1. What are u plan for the car? (DD/semi-track/track/drift/autoX)
2. How is the road condition around u?

The car is currently a DD/WW & semi-track car. I drive the car when it is operational to work & back which is about 5 miles each way. Sometimes take it out for cruise or to store. Road raced 4 weekend events last year, but none this year while focusing time/money on modifying & making changes to car. Hope to get back to the track some next year & plan to occaionally trip to the drag strip just for shits & giggles. Eventually car will become a track only car, but figure that will still be a ways off. Road conditions in my area of town are not real bad, but surrounding areas can get pretty ugly. I don't intend on slamming the car, only lower to improve performance.

are you actually sponsored by ARK, or just have some of their products?

Running the Stance units on our car. They're not too bad. Had to request for a shorter front spring though so it could be adjusted lower to kill the gap running 18's.

nguyen128

I know it's not on the list of choices but how about BC? If not then I vote Stance, those were my second choice.

Yes, but only semi-sponsorship meaning no long term commitment from them. They determine if they wish to help me out on each individual purchase as they feel the need to promote that product at that point. Part of the agreement is for me to run their decals on the outside of my vehicle, give reviews on the products I've purchased & show footage of track events &/or car shows.

However, my other 3 sponsors are not semi. CBW is full on sponsorship & I don't pay for anything. MAP is regular sponsorship & they take very good care of me, esp with their in-house work. Forged is regular sponsor, but more oriented toward dyno time & tuning (if they still plan to do so).

These are the only decals I will run on the outside of my vehicle besides TiC which is not a sponsor of mine, but I have done product testing for them & hope to do more in the future.

I only include those that actually sponsor me in one form or another in my sig. If I listed product name brands that I have, my sig would go on forever since I'm not any particular brand fan boy, but more of a pick the best part for that job kinda guy.


Well BC almost made the finals since they have pillowball mount, monotube design & camber plates (some applications), but I didn't care for the 30+ adjustment increments along with a few reviews of folks complaining about them being a bit too soft. In addition, from what I've researched it looks like ARK & Stance build quality is above BC, Megan, Tein, Ksport, etc. KW might have made the cut it it were not for the rubbing issues some members are having with them vs some of the other options.

I was hoping to get some more responses from current owners of either of these setups along with more voting before the poll closes at the end of the month. C'mon just give me your feedback whether good or bad on either coil over system. I know there is alot of people out there running both of these and some of you actually track your vehicles.

Thanks,

Jerry

anything but ark. so.....i vote stance or BC.

SLeRoux92

Tein>Stance>Ark (IMO)

giaolong

This height, on Megan set at 20 damper and its super comfort for me. And i noticed im faster and tighter in corners too.

From what I understand, if you know exactly what you want, then you can get custom valving on the BC's, which might eliminate the possibility of being too soft. I believe Tom said something about it a while ago.

Tufast

Thanks for all of your posts. It made me take another look at BCs & give them a try.


I've ran across alot of threads on this forum as well as several other forums with positive views of BC coil-overs that have caused me to investigate BCs a little better. I used to hear alot negative feed back about them including they are just Megans with different decals. I'm not knocking those who own Megans as they are certainly better than K-Sports from what I gather. However, I feel for a little more money better coil-overs can be gotten. After doing some research it seems the negative comments have eased some over the years as BC had made some major changes around 2007 & have continuously gotten better every year. So I figured it be worth looking into them as a possibility.

I actually spent several days on just one thread on NASIOC that was like 90 pages long. But I looked on other Subie forums, Evo forums, Honda forums, even Tire Rack feed back forum to get to the truth about these coil-overs. The truth is they are made in Taiwan in a major factory that actually makes alot of other coil-overs for other companies to their specifications then stamp the other company name on them. They have good support although sometimes difficult to get in touch with the company themselves, U.S vendors seem ready & willing to get what needs to be done. They are warrantied fully during the first year then can be repbuilt/replaced for $95ea each year after that (WoW). I found 95% of the complaints were resolved with some sorta of adjustment or tightening on the user's end. Truth is they pretty damn good for what you pay & the consensus is that the more recent models are better that K-Sport (of course), Megan & Tein. Several BC customers that had owned KW & Stance felt the BCs were on par if not better. One STI owner who had used KW V1s, KW V2s, KW V3s, Tein Basic wagon, Tein Basic, Tein SS, Tein SS w/pillow ball mts, Tein GT Flex wagon, Tein Flex, H&R Street Performance, H&R RSS & KSport felt that the BC BRs were better all around including ride, handling & stance.

Anyhow, not long after I originally began my search I was offered a hell of a deal on a set of these that I would be retarded to turn down. That made my search even more intense & I started looking into different spring rates & variations on the BC offerings. Now it looks like I will be getting some pretty stiff custom spring rates & custom valving to go along with it.

For your custom spring rates I would suggest 10kg front and 12kg rear.

I have the Ark DTP's with 12kg front, 10kg rear and I am pretty sure they got it backwards. It doesn't affect the handling that negatively, since you can adjust the handling behavior via dampening. It's just seems to me that it would be more optimal with the spring rates switched since I wish I could have softer dampening in the front with stiffer in the rear (even with the rear at full stiff). But that's just on the drag strip. When turns are required and DD'ing, I soften the rear and stiffen the front, but the front still much softer than the rear.

If you never hit the drag strip, I think the DTP's spring rates are probably fine for other tracks.

Thanks for your response as it makes me feel more comfortable going with spring rates this stiff. The coil-overs I'm getting are used with about 3k miles already on them with rates same as yours 12k (F) & 10k (R) along with custom valving for dampening.

How is the DD ride with yours at those spring rates? Any comparison to Track suspension? I'm not looking for a soft ride, just one that is bareable.

Since I will be mostly road racing, I'm hoping that these spring rates will be more conducive to that type of environment. I only plan a drag strip event intermittently after completing a stage of mods to see what she is capable of.

I originally thought stiffer spring rates in the rear would help with throttle steering & such. But after seeing spring rates for other vehicles on other forums, it seems most go with spring rates that are stiffer on which ever end of the car that is heavier. In our case that would be the front. However the base spring rates for the Genesis Coupe for BC BRs are 5k (F) & 8k (R) and the base spring rates for Stance GR+ are 6k & 7k.

General question;
Do you think that the stiffer spring rates in the front will help with the understeer issues our cars have creating more bite or will it hender due to the extreme stiffness causing more push from the front tires to sliding?

I plan on replacing sway bars at the same time of the coil-over install followed by a quality alignment at a race shop with corner balancing. I'm hoping with all this the suspension tuning will be good. I'm also thinking serously of installing the MaxUSA rear frame risers as well as some adjustable rear traction links.
