[Cobalt]

Old thread and I have since moved on and would need to pull up my records to verify but we came up with 12.5mm increase per side using 993 longitudinals on a 964 and modifying the 964 control arms to work with the RS uprights.

Everything has been upgraded or custom made. I am using ERP and Tarrett products which are essentially all modified versions of the older factory RS stuff. based on my driving I always had even tire wear on track.





Only pics I can find but after we made the mods this is how the wheel fit and before as you can see a considerable difference visually. The math will need to be revisited.
