F#*&IN proxy server error !!!!! Can’t post can’t search what the F$#@! I’m sorry if this info is out there somewhere, but I can’t get to it. What are you first gen CSP guys running for wheel & tire size? I’m really looking for wheel width, diameter & offset. I was thinking about going 14x8’s all the way around, not sure about offset yet? Can I get wider? It’s an autocross only car so I don’t care how far they stick out.

 

I Run 13x8 with a 0 offset works goog for me

 

Can I get 13's over SE rotors and calipers?

 

YES.

But shop carefully and know what you need. It is easy enough to measure the required internal diameter and most wheel companies should be able to provide that info.

For reference I use 13x8 Diamond Racing Wheels. I think I have a 4.5" backspace.

 

I was thinking Diamond Racing as well but in 13x9's with 235 or 225 race rubber?

 

My opinion is that 13x8 will be a little more versatile. You could go as low as a 215 tire if you wanted to and 235 is also possible. You may also start running into clearance issues with a 13x9. I currently run 225-50-13 Hoosiers on the rear and I get a slight rub on my rear fender lips (they are rolled). Of course it is really low also. I could raise it a bit but the rub is so minimal I don't feel the need. On the fronts I have 225-45-13s with no rubbing. The first area of concern is between the coil over spring perch and the inside wall of the tire. This is why I went to a 4.5" backspace instead of 4". If they were offered at 4.25 it may work but it would be really close.

 

I haven't purchased the coilovers yet, but I thought this might be an area of concern, so the GC's race version of their coilover setup (weld on low profile perch) I thought would be a better choice? However, I do like the versatility of the 8 inch wheels and I don't weld so maybe the 13x8's are a better choice? Hmmmmm...... More food for thought.....thanks for the insight.
