It's very well known. The conclusion I've come to is that if you want to run a 17x9 up front with at least a 245 tire, some form of fender work is inevitable, because under the right circumstance there is always the possibility of the tire catching the fender.

So, run a 3mm spacer and don't go full send on the front camber to make +63 function perfectly at stock height. Got it, lol.

 

Gotta be mostly the stock ride height thing. Like I said, +63mm here and never once have touched the control arm. But I am lowered roughly an inch. If the ride height were higher, I can see that angle difference placing the control arm closer to the top of the wheel and thus increasing the chance of this occurring.

 

Yeah, but still have to roll the fenders and tabs - that's what I was hoping to avoid

 

What is your suspension setup?

 

I'm on the stock suspension with Spoon offset ball joints running -3.2 camber on the TRM C3 wheels (17x9, +63 offset) and can confirm you will rub the control arms at full lock. Its not really an issue unless you go full lock all the time.

That being said, I am truly sad Tire Rack decided to kill off the C3 lineup and give us no replacements.

I know the 17x9 +45, RPF1s will fit and allow to go square but under my time attack rules: "The widest point of the tire, above the axle, does not protrude more than 13mm (0.5”) from the widest point of the OE wheel well opening when measured in a vertical plane coincident with the axle line." Will 255 work up front even with my camber? I've been doing a LOT of research and I'm doubting from photos that it will abide by that rule. My current C3s have seen enough track days and I don't want to find out the hard way they should've been retired earlier. RPF1s are the most economical choice but might leave me gimped for maximum grip without breaking the rules.

 

Hyperco springs/TC Kline dampers using koni sleeves/perches
750F/600R spring rates
Lowered roughly an inch
-2.6 degrees of camber all the way around
Doesnt matter for the rubbing considerations, but a moddiction front bar/stock rear bar

 

@LemonJus From what I found the TSW Nurburgring is $20 less than the RPF1, a stronger construction method, and has more friendly offsets while only being 0.6 pounds heavier. I'd give that a serious consideration especially because there are some reports of the RPF1's showing early wear and such from serious track work. Beyond that though, and should you have the money, going fully forged would be your best bet. But yeah, sad to see the C3 go, especially with no replacement on the way.

@engifineer It's very interesting that lowering a bit allows you to clear the control arms so easily. These cars are so picky about what fits, lol.

 

The TSWs almost seem too good to be true. I'm always scratching my head at that value proposition - what's the catch? I keep asking myself.

 

The catch is, they're not very attractive IMHO, and there are reports of the finish being poor quality (reports of it coming off).
