I'm going to eventually install a full PBM suspension and will add more info and pics of my installations as I get them.

1. Here's a pic of my pro coil overs and sub frame risers/bushings installed. The coil overs were a simple straight forward install. There is no clunking or noise. They perform amazing and are more than comfortable for DD at their softest setting. They come with all the adjustment nobs so you can adjust anytime in a matter of seconds once installed correctly. My profile pic is of me in a 3rd gear drift. You can see how flat my car is staying. The feel, feedback and control is great. Could not ask for more. There is a large pic in my photo album.
2. The install of the SFR's is a little more difficult. If you have the proper tools it is 100 times easier. The hardest part is getting the original sub frame bushings out. That means cutting them out. You can do all of the install without removing the sub frame with the proper jacks and stands. I believe there is a detailed description of the installation procedures if you search on google. The SFR's raised my roll center about a 1/2" and got rid of those soft factory bushings. As you probably already know, if you lowered your car the rear arms are angled up towards the wheels. Mine still angle up but not as much. For those who are really about performance, having your roll center as close to optimum is essential.

3. I had to replace my rear toe rods because I bent one of the rods. The stock rods are only good for DD. I could not believe how light and thin they actually are. The PBM toe rods are beasts compared to the stock ones. The toe rods have taper ties on the ends so they are in tight. You are not going to be able to simply pop or even beat them out. You need to use one of those fork looking things that have wedge shaped ends that they use to pull ball joints or some kind of puller.

My next Powered By Max USA mod will be the rear upper and lower control arms. Have you ever hit a bump and it feels like the rear just bounced in the air? That is not you hitting the strut bump stop nor the springs bottoming out. It is your upper control arm hitting the uni-body. I only have 1" between the upper control arm and the body. That is awful travel. Also, the lower control arms binds. You can see this when you jack up the car and the lower rear control arm stops going down. If you loosen the camber bolt at the sub frame the binding at the bushing is released and the arm goes lower. I'm just looking to actually utilize the full potential of the coil overs and not limit them.

holy crap! That's how my control arms look when I messed both sides up.

1320drift · 01-22-2012, 01:13 PM

Yeah, I did that at Adams. Got the rear off track and smacked the tires on the outside of the turn. Just hit the turn to hot. My wheel didn't get damaged only the toe rod bent. Pretty weak part. Stig. did you want those measurements to modify your toe rods?

WhiteGenCoupe74 · 01-22-2012, 05:08 PM

i think im gonna do the max coilovers

1320drift · 01-22-2012, 06:34 PM

I used to have sportlines for a few thousand miles and these are much more comfortable for DD. I was surprised at how well they handle at full soft.

damn. taht sucks.

Ive told errbody already that the stock control arms are weak sace and a pile of crap. Thank god PBM makes them now. I whish they made them when this happened to me the 1st time.

Yes please, send me those pics. I pmd you my emai address.

OK, I going to probably work on my car again in a couple of weeks so I will have pics and measurements I can send to you then.

I'm in the market for coilovers.
So far I'm decided on Stance.
I've looked into these before but couldn't find much information on this specific application.
#1 - What's the price point of these?
#2 - I realize this are meant to go really low? But I only want to go as low as having 2 finger gap in the wheel well, is that possible?
#3 - How is the performance/quality/durability of these compared to Stance?

Hope someone can help me out a bit, thanks in advance!

1. $1350
2. I have a one finger gap so I don't think a 2 finger gap will be a problem.
3. Quality was the first thing I was impressed with. Every piece is percisely made. You can diffenetly tell they are high quality by the workmanship of all the pieces.
Durability; I have had them for about 4 months and have been to the track about 5 times. I drive extremely aggressively on the track. I am unforgiving and constantly push my car passed its limits. I have been off track in the dirt, gone over the curb/bump on the inside of some turns at speed and even hit some tires used as a barrier on the outside of a turn. The coils are still like new. PBM USA is in so cal so if you need part replacement it should not be a problem. Don't quote me on this but I believe they sell dampeners and springs at different rates too.
Performance: If you are a grip guy you can set the coils up to do just that. I can set up the coils so the back never breaks loose and the car just tracks the line. I have adjusted the coils to understeer and oversteer. Of Course camber, tires and pressure have a lot to do with that too.

I don't see how anyone would be unhappy with these coils. I love the fact that they are true coil overs. I can't help you on the stance coils as I have never had them.

And you're not using any sort of reinforcement for the rear suspension since you switched to those coilovers?

PBM is known for their quality, but relocating the rear springs is one little detail that's throwing a chill down my spine. On old BMWs, you don't do that without welding a crossbar between strut towers to reinforce them (making the entire trunk useless)

I change my wheels probably 1 to 2 times a month when I go to the track and I do an inspection of my suspension everytime. I have not found any problems, not even a loose bolt. One of my rear wheels comes off the ground when I enter almost every driveway. I guess that is from our stiff chassis and the coil overs. I really do drive my car hard on the track so if anyone is going to see any damage from the rear coils it would be me. I think there are companies that make a rear strut bar that installs really close to the back seat.

Trust me when I say my car also sees quite a bit more stress per mile than the average driver puts it through. I'm still skeptical to see the long terms of this. Totally tempting to take the plunge and do it (I know I've paid the real price for getting SMAs), but I'm not quite sold on these yet

As for a rear strut bar, I'm curious as to how those would "mount", considering the bolt on spots for the rear suspension is in the wheel well (and not the cabin/trunk itself)

subscrib'd for more details.

I understand your concerns but I think Hyundai did an excellent job of building a rigid chassis. It is definitely stiffer than any other car I've owned. I think the weight of the car reflects the amount of steel they used to build the unibody. To me the rear is the most rigid part of the car. The trunk is completely enclosed except for the opening at the back seat. If you remove the trunk lining you can see added sheet metal around the opening and at other spots. I know Nissan stiffened the 350z sub frame in 06 and did not bother to stiffen the strut towers, which shows me where their concerns were. I would imagine the 350z is not as rigid as our cars with that open trunk hatch design.

As far as the rear strut tower brace, I agree with you that it is needed for guys who push their cars beyond its limits. But I don't agree that having true coil overs is the reason to get it. The rear strut brace is going to help reduce flex under extreme braking, which I do a lot on the track but almost never on the street. I would guess that 90% of the gc owners would never reap the benefit of having the brace. 1. Your not going to consistently brake as hard as you can except on the track 2. Very few gc owners have disconnected their abs, which I hate along with all those other electronic help me drive features that they put in cars so the general public don't kill themselves.

This just my opinion and experience. Not trying to offend anyone. I will post up a pic of my rear strut brace so you can check it out.

Hey drift1320 how are the Sub Frame Risers as far as daily driving?

I have not noticed any difference in the dd ride quality since I installed them. If there is I think the dampeners set at full soft just absorb it.

Sure, I'm not offended or calling you out by any means. Just stating my opinion. The fact that you put your car on the track already gives you credibility to your words.

I appreciate your words and follow up with the picture via PM. Replacing my coilovers are nowhere near on my priorities list, but if a time comes for it to happen, I will definitely consider PBM.

+1 on rides unbelievably well on full soft.

stylesp · 02-16-2012, 03:03 PM

where can these coils be purchased ?

1320drift · 02-16-2012, 04:55 PM

I think their site is Poweredbymax.net . Google search with the whole name will pull up their site too. Powered by Max is bringing a gc with their full suspension system out to a drift event I am going to at the end of the month so I will have some vids to post then.
