Will these work on a narrow body C2?

18x8.5 ET40 backspacing 6.25 (1"outer 7.5"inner)

18x11 ET60 backspacing 8.375
(1.5"outer 9.5"inner)

Rears I'm not too worried about because I can add a spacer but any information would be appreciated.

From my knowledge they were on a 993 Cup Car.

 

You're gonna have to align the car aggressive for fitment and probably massage the metal to make room, and even then they might still rub slightly. Are you planning on running normal sized tires or going for the under-tired stretch/stance look? Are you planning on driving the car hard or cruising/hard parking?

 

Read through BLACK-BETTY's response in this thread. That's a good example of an aggressive setup w/ lots of rubber on the road and function in mind.

Hi!

You'll also find even more wheel info on the first post of my thread 'Back in Black'.

PM anytime with wheel specs.

 

Does anyone know what the offsets would be for the most aggressive setup without having to roll the fenders? Trying to decide what way to go on my new wheels. I'm thinking 10et43 on the rears and 8.5et48 on the front. Thanks in advance.

 

That would be close. DuWerke has 10 et46 and 8.5 et46 with gently massaged fenders because of how low he is. If you don't go as low you can get away with it, or add more neg camber.

 

Oooo don't know that one. That's a trial and error campaign that'll involve spacers. You know... rolling arches ain't that tough.

You need to find a body shop that's got one of these. Then a heat gun and you're away.

Yup - but that's with stretch tyres so not applicable for standard tyres. For reference I'm running ET47 8.5J 225 and ET32 10J 265.

 

Thanks for the specs. Gives me something to work with.

Frank, I've seen your numbers. That rear ET seems like it would make the wheels stick out so much more than it shows on your pic. But you're right, a bit of trial and error is what I'm going to have to do. Will look into the rolled arches. The wheels I have are 8.5 ET 52 and 10 ET 47. So I will also look into getting spacers to achieve the look I want.

Thanks again Maxxvr and Frank for the quick response.

 

Quick one regarding arch rolling, not many companies have a 'roller that will for the Porsche PCD. It took me a while to find someone who could do the front and rear.

Pic for Dino attached as requested.

It's the -3 degrees of negative camber that tucks them in. Note -3 is very aggressive especially for a C2 non dedicated track car.

That's an ideal starting point. In my mind - set your ideal geo first, then get the wheels on and see what spacers you need.

What's worth noting - I wouldn't recommend it safe to use shims bigger than 5mm. Should you wish to - I suggest changing the wheel carrier studs for longer ones so the thread is not further reduced.

 

Thanks Frank. Duly noted on all points. Will do a follow up once I get the wheels back and mounted on the car.
