i have look and could not find anything about what im lookin for... i need some help
i had a set of Volk GT-C but they could not be fixed so... i plan on gettin some Rota Grids P45R 18x9.5 but im not sure what offset to get. 12? 25? 30?. which would be the best to run on the GC..
thanks for your help.

Grids and P45Rs are different wheels. Are you staggering front to rear? I thought 9.5s would rub in the front?

9.5s are too wide in the front. I was running them at the track and when spacered out to clear the strut they stick out almost an inch past the edge of the fender.

dam i didnt even know that.. thank god i didn't order them already i would have been mad.. what size should i run in the front.. and no i was not goin to do staggered.

davisk6

I would suggest an 8.5" with an offset less than +35 for the front. You can probably go as high as 9", but you would need an offset in the +20 range.

AnalogHero

really? i was gonna go with a 9 wide with +25 for the fronts.

are the stock front wheels 8 wide with +35? if so, i used an offset calculator and said it'll only be 3mm less from the strut housing clearing.

davisk6

Brake clearance should be your first concern. If you have the Brembos, I wouldn't go lower than a +20, otherwise I don't see why a +25 wouldn't fit. Here are the wheel specs:

Front
Wheel Size: 18" x 7.5"
Wheel Offset: +35

Rear:
Wheel Size: 18" x 8"
Wheel Offset: +35

Track Wheel Specs:

Front:
Wheel Size: 19" x 8"
Wheel Offset: +35

Rear
Wheel Size: 19" x 8.5"
Wheel Offset: +35

Good luck with it

Amen to that. I hit a rut with my old Rotas and thought I had a flat. Turns out the inside of the wheel blew out. It's a sad state when the tire is harder than the wheel.

N2OInferno

That's right. You should only spend a ridiculous amount of money on wheels.

Oh wait... HREs got banned from some sanctions because of quality issues too.

Personally I want some custom Sub Zeroes that have been uh... twisted.


But just because you can pull up some images online of broken wheels doesn't mean that every single one is going to suffer the same fate.

Has Rota improved their quality? I remember when that image first hit the net, it really was a pretty common problem for Rotas, they just weren't made well. I've heard reports that as of late they are decent wheels nowadays.

I would say about 25% of the people I have known who had Rotas had problems with them

I don't know anyone that's ever had a problem with Rotas.

I think they make some OEM wheels too but I'm not sure for which company.

Oh, the picture I posted is because the caliper was rubbing against the spokes btw. But nobody will actually read this and relate it to my last post lol.

Facts:

- HRE Was never banned from any track events, these were mainly rumors. HRE has publically cleared their name, and proved these accusations to be false. Check 6speedonline if you don't believe me.

- The picture of the wheel people thought was an HRE was actually a Kinesis wheel.

- Volk GT-Cs are already heavy, Rotas are heavier.

- Forged > High quality cast > Low quality cast (Rota)

- You can get quality enkei or work wheel these days for within 1000-1200 a set brand new. Hell, you can buy used TE37s or SSR Type Cs for under 1200 used.

- A cheap cast wheel does not have the heat tolerances or stress tolerances a higher quality cast or forged wheel has.

- If rota was "racing" quality, their wheels would be on fully sanctioned touring car race cars (Super GT, Super Taikyu, ALMS, Formula 1), not just some amateur time attack car sponsored by rota or their distributors (and then try to claim their stuff is "time attack" quality).

Quality companies like OZ, Enkei, Technomagnesio, Team Racing Dynamics, SSR Wheels, etc have proven they have the technology to make racing quality, and inject their racing technology into their street products to make a variety quality, LIGHTWEIGHT, durable wheels for high performance street cars.

PAWI, the parent company of ROTA, made oem wheels for toyota, and various other manfufacturers in the philipine market mainly because the cars were dirt cheap, and the oem stuff needed to be barely above the bar. Cost effectiveness was the key there. Not all OEM stuff is extremely high quality.

Simple logic states that Rotas (along with other reverse engineered wheels) = Fail. Is anyone a cheapass? No, then don't wheels that belong on a honda civic 4 door with a big wing on a real sportscar.

I won't beat the dead horse anymore.

Maybe it is an issue of people who only ever streeted them and have decent roads never saw a problem and they only start to show their weaknesses when they are pushed? I have no clue really. It would surely be nice if the quality was there, because the prices are great for the styles.

i know there are issues with rota's but comeon there are so many people running them that never have issues.

is that to say that there aren't issues with other brands of wheels? there maybe...but it seems that rota always seems to get attacked because they are in expensive ...i won't say cheap, because some of there wheels cost some good $.

i am not saying that you don't get what you pay for but i know wheeldude has sold a crap load of them and my brother works for a tire place in FL that sells get this - a knock off of rota...so we have a knock off of a knock off. now that is something to think twice before buying.

i think rota's are pretty much all for show though as they are heavy but i like there products esp. for the $.

FUD, that's all I have to say. Not everyone has 2k to spend on rims plus the other 1k for the tires.

Well, my information was wrong I guess. I got it here:

and had seen it all over the place so I figured it was legit. My bad. I thought everything on the internet was true!!!! I can admit it when I was wrong though.

Oddly it seems the 6speed thread goes on to eventually say that HREs are okay, but then someone comes out with a quote from a source saying that they were banned but they're fixed now.. Either way, it looks like they're alright to run now. Which is good considering you just spend 1/4 of the price of your car on wheels and tires.

Some people hate Rotas. Same can be said about Sportmax, XXR, Drag, and Konig. They wouldn't be seen dead with them. It's personal preference. I've seen tons of sets of them with no issues, most are daily driven street cars but a few see track use. For daily driving they're going to be fine, and honestly what fraction of people

Of course a forged wheel is going to be better than a cast wheel. But the difference is somewhat like comparing the Hyundai Genesis to a 911 GT3.

Point is, any wheel can break under extreme stress. I personally wouldn't use a daily driver as a track car because stuff happens at the track and things break..


This picture makes me sad. Note: no idea how it happened.

If I had my choice though I think I'd go with Enkei RPF01... so hot.

OP, if you like the style of the P45R Rotas but want higher quality and have the money to spend, the real deal is the Nismo LMGT4. They really are a nice style wheel.

Fixed for accuracy. If you can't afford to do it right, you always have stock wheels. You don't need fancy wheels to go fast.

Rotas get attacked because they are not an improvement over stock. They can never be on the same level as the originators. It's because of the originators and the cheap excuse givers that their very existance is based on.

China sells a ton of kung pao special exhaust manifolds to cheapasses too, doesn't make it great. They realized they can't sell it directly as chinese/knockoff, so they started trying to infiltrate the market with names like Rotora, Megan Racing, XXR/Sportmax wheels, BC Coilovers, K sport, D2, and other brands. But, slowly, people found out it was just junk.

A K Sport or D2 Coilover can never have the adjustment and quality as a KW Variant 3, and the Shock dynos prove it. The K Sport and D2 brakes can never function like the AP Racing or ALCONs, and the Rotoras can never be on the same level as the Brembos they sought to copy.

Call the excuse givers out on it, they give the "I am going to college, and can't afford it" deal. Why are you spending on luxuries if you can't afford it?

You mean to say you like the styles that they copied, but don't want real engineering behind your wheels. Copies are exactly as you described them: All show, no go. The knockoff industry will continue to cannibalize itself and soon collapse inside out when they cannot keep up with the originators.

It's pretty cut and simple. Buy if you want to look good, but that's about it.

N20: You make good points, every wheel can break. Put a TE37 through 50 HARD track days and eventually it will crack too. It's why race teams get rid of their wheels every 1-2 years. Eventually the stress can get to them. But a low quality wheel will disintegrate that MUCH quicker, if you get what i mean.

I think the LMGT4 is discontinued: Which is quite sad, but they can be found used for somewhat cheap these days.

LOL, and we got another elitist. Look you're not going to change anyone's mind or break their hearts spilling your guts out on why you love your "boutique brand" wheels so much, so quit your crying and buck up pal.
