Checking spacer size and seeking mfg recommendation
 

I am very seriously looking at putting a set of 993 Cup 2s on my 1986 951. 7 x 17" front and 9 x 17" rear, both 55mm offset.

Given that the stock 951 comes with 7 x 16" et 23mm and 8 x16" et 10mm (please tell me if I am wrong), my calculations (ably assisted by 1010tires.com) tell me that 32mm (1.25") spacers in the front and 38mm (1.5") spacers in the rear will reasonably approximate the original set up. Can someone please confirm that I am correct?

If so, please recommend a good source for spacers (taking into consideration that this car is a street car only and that I am on a bit of a budget).

Thanks

This guy seems to have the best pricing. It's where I plan on getting mine. I would go with 31mm & 37mm spacers though (offset you have is actually 23.3)

Do mean these? These are C2 Turbo (1990-1991 i think). They are 7.5" x 17 and
9" x 17. If your car came with the "early offset" 23.3 ET you will need spacers to make up the difference from the 53 ET (mm) latre offset wheels you want to put on. They look great for street :rolleyes:

I am looking at both those and the 993 Cups - they are quite similar. Yes I have the early offsets and need to get the spacers. That's why I am asking.
