Sorry, i know you all get lots of these questions and i have tried to work it out but i'm obviously a bit dim...

Would 993 Cup's 16" front 7" (ET 55) rear 9" (ET70) fit my 1991 S2 with or without spacers?

I notice RPM Technic has an S2 track car for sale on Pistonheads with the same style wheels but i'm not sure if these are the same sizes.

Many thanks

IIRC, RPM's car has 17" Cup 1s.

Yes they will fit (assuming the offsets are between 50-62), but some may argue that your fronts are a tad narrow, considering the wheels are off a 911, and hence designed for a car with no weight up front.

This is from the description & from photo it looks like the 16" 993 cup; the advert for the wheels sales the 9" rear has a ET70 offset.

They look like 17" cup 1s to me in fact they look identical to those I have on my 1991 S2.

I dont know if you can enlarge that picture but they are definitely not 17" cup1's - its hard to see when the pic is small and they are painted black.

You'll need spacers to bring the rears out or they will sit well inside the arch.

You'll need Hubcentric spacers to space them out right, otherwise it may look odd + they may catch. I'd get 20mm hubcentric spacers if you got them. Better still, look out for a set of wheels made to fit the 944 better off in the first place.

But are the originals not 7/8? and are spacers safe?

Theyll certainly fit and the offsets are virtually perfect.

Sorry I looked at the 944 S2 car on the RPM Technik website from your link not the little picture so as you say those are defo not Cup1s.
