Wheel Spacers

I'm 99% certain they were 18mm and with 17x9" MM wheels. Strictly speaking as Dave says they're shims. Bought 8 or 9 years ago they 21mm Porsche ones as recommended in one of Adrian Palmers original articles. However with them I couldn't fit the MM wheels so had them machined down. Still run them with the original 9" cup wheels so will measure them tomorrow to be sure.
Am about to fit 17x9 Dymags with a 58 offset so that should be interesting!

Tony,

21 mm was the original Cup spacer used with ET 68 and a 9,5" wheel. So no wonder MMs (ET 47, 9") don´t fit with 21 mm spacers. Will be interesting how big they are now after being machined down.

What I mentioned in a post above means that there is a few mm space left, so the wheels will never touch the rolled arches. (Although I run little neg camber in the rear for road use from time to time) You can go a little closer (i. e. a little bigger spacer), but I doubt it makes sense. It also depends on how much neg camber you run. That makes a big difference, too. But then the inside clearance has to be checked properly. And, no two cars are exactly the same. If it works on one car only just, that doesn´t mean the wheels/spacer combination will fit on any other car.

I personally prefer enough clearance to make sure the tyres don´t touch.

Rgds,

Hacki,

Thanks for the reply, I thought that was your post implied, was just looking for confirmation, before I shell out for 15mm spacers.

Tony, thanks - it looks like we have an answer. I'm going to order some 15mm spacers before the end of the week.
 
It might be worth mentioning here that each additional degree of negative camber approximates to something like an additional 5mm of clearance between the top of the wheel and the wheel arch. The maths aren't THAT accurate, but it gives you an idea.

Regards

Dave
 
Spacers are definitely 18mm, car is running just under 21/2 degrees negative camber and 255/40 Rossos. Must stress this is with std mag wheels.
Won't work with the Dymags, flange is too deep so if anybody has any hub centric shims of 6 - 9 mm I'm in the market!

Tony
 
thanks Tony, standard Mags are ET 55 I think, so I can see how that would work. Dave, I had no idea that camber would make that much difference. Not to suggest that I would ever use camber to fix the wheel fitment of course.
 
Last word on the subject -you might find this useful.

Not just camber, ride height too -think about it......

Couldn't be bothered to spell it out, but this site stresses the knock-on effect of altering camber/ride height etc....:

Hugh, I have a pair of 21mm and 15mm spacers with bolts, and 9mm spacers without.

Would you like to borrow them to see how they fit ?

If so, let me have your address and I can send them to you tomorrow by courier.

I'm otherwise away until Monday of next week ...
 
Hugh, FYI I have Cargraphic 18mm spacers with original ET55 mags on my RS and they really fill the arches nicely with no rubbing. I noticed a set for sale on Pistonheads (says to fit 1994 car onwards but can't think why a set of 94 spacers wouldn't fit a 92 car as they are all 130mm PCD).
Linked if its any help: http://www.pistonheads.com/sales/1403492.htm
 
They've sold already!!! Thanks, I'm going to try Chris's spacers and report back. Will keep my eyes posted on ebay and pistonheads. I've got to say that set for 60quid was a bargin.
 
Folks, just to close this thread out - finally.

So with a ride height of 224mm at the rear, and a camber of 2 1/2 degrees, I can now fit my et47 MM cup 1 replicas with Toyo R888s and 15mm spacers.

Many thanks to Chris to lending me the spacers.

With a ride height of 221 and camber of 1 1/2 degrees the toyos wouldnt fit, but the S02s would (on cup 1s with ET 55, so effectively the same as the MMs and a 15mm spacer)!!

One day that will be useful to someone perhaps......[:D]
 
Hopefully you'll see the benefit at Silverstone. I'll be on a slow boat to Zebrugge. See you at Spa!
