Wheel advice

That's useful info Ed. Did you have to grind the rear callipers for the 7R? I'd be surprised, but in which case it is a no go for me. Or are you only grinding at the front with the bigger caliper? I can easily insert a finger around front and rear callipers and wheel with my S callipers and Flat 6s. So surprised that grinding is needed anywhere. Not going to do mods that I can't reverse easily. 5/8" is essentially 16 mm. Why the different spacers front and rear? And finally 16 mm seems a lot, with a risk of fender rubbing. What was the min clearance you needed in the rear? Did you just want the face of the tires to match front to rear? Is that why you chose the same spacers (effectively)?

Sorry for the barrage of questions.

Hi Ravi,

I have deep 6 Fuchs on the front and 7R Fuchs on the rear. Harvey added the extra inch to the inside of real deep 6 Fuchs.

Front tires - Pirelli P6000 - 195/65-15 7 mm spacer
Rear tires - Pirelli P6000 - 215/60-15 15 mm spacer

The car is lowered to Euro height with some negative camber around -2 degrees in the rear.

Over big bumps my driver rear tire would rub against the fender lip. So I reduced the rear spacer to 12 mm and that seems to have solved the rubbing issue. The inside of the rear tire is about 7-8 mm from the rear spring plate bolt.

I did not roll the rear fender lips. These cars are hand made and not equal on either side.

I tried different rear spacers and 16 mm would not fit at all.

I do like the extra grip from the wider rear tires.

Ravi,
I realize these are cast replica's instead of forged originals but are you aware of these wheels as an option?

Great ideas everyone. Thanks for the pointers. I think I had seen the TRE wheels a few years ago and forgotten about them. EB Motorsports in the UK makes an aluminium Fuchs replica that is super light (and 3 times the price of the TRE one!). I'm not too worried about weight. I'm not competitively racing.

Bert, you obviously would have to use longer wheel studs with a 12 mm spacer, which I think I don't want to do. I'd rather leave the mechanicals stock for interchangeability with the original wheels (don't know why, because I'm not doing shows, but just something I want to do I guess). BTW, that Fuchs wheel you sold me years ago is now living a sunny life in Australia. Nice to hear from you.

Hi Ravi,

I did install longer wheel studs. You could also try wheel adapters to avoid the longer wheel studs. I know that 15 mm adapters exist. Not sure on 12 mm versions.

Glad the Fuchs wheel found a good home.

I think there is about 15 mm of exposed thread on the standard studs, so you need at least a 15 mm deep adapter so the studs don't protrude past the spacer. So I think that sets the lower limit unfortunately.
