I have that exact suspension from that car sitting in my garage waiting to be installed in the spring. I bought it off of him on this site about a month ago. They are K-sport coilovers.

 

Do the SP600s fit when lowered on coilovers? And does the back trailing arm need to be changed to an aftermarket one? (when lowered)

 

I didnt have to change anything. I'm on ground control 275 rear 245 front

 

Yes.

No. You won't need an aftermarket trailing arm to run wider tires on the CCWs. I have run as wide as a 295 in the rear (although only lowered about 0.5" at that time). I currently run a 285 and I have my car really low in the rear and it only slightly rubs on sharp turns, nothing that can't be tweaked by raising the ride height a little bit (1/4"-3/8").

These CCWs have a great offset for our cars that allows a very wide range of tire widths to be run, whether stock ride height or lowered 1.5".

 

Thanks! Do you have any pics of your wheels?

What's up guys! My SP600's are 19x9 and 19x10. Running 255/40 upfront and 285/35 in the rear wrapped in Nitto Invos. But my rear tires are bald now, debating on switching over to Hankooks... we shall see.

 

hankooks ftw

 

Yup . .
