I tried to search for this, but any way I tried to word my search, the 15" portion of the text got dropped from my search...

I have some 15" x 7" ET30 SSR Type Cs from my road racing CRX. I have sets with Hoosier A6s, Toyo R-888s and RA-1s, all in 205/50/15. Has anyone tried running 205/15/15s up front with 225/45/15s in the rear, or 205/50/15s all around? This would be a preferable setup for me as I have lkots of 205s, but if those would be insufficient out back, the 225/45/15s would also fit the CRX, and I wouldn't have to buy any additional rolling stock.

Looking forward to getting the Lotus on the track. I've just reached the end of the break in mileage, and have a track day scheduled in a couple of weeks. I've seen some posts that the base suspension is too soft for R-compound tires, but to what end? I can see un-weighting a rear wheel in really tight low speed corners, but if you're smooth and patient with the throttle that should me managable. Am I missing something?

FWIW, I fully intend to upgrade the shocks / springs if and as needed, but not until I evaluate the car as Lotus delivered it. The boys at Hethel are renowned for their suspension design and setup work, so I have to believe the car is pretty good as delivered, even if it is somewhat compromised for the street.

Thanks in advance for your responses.

You may want to do some research on tire stagger issues. I read a post that said Lotus with same size front and rear will have problems with traction control kicking it. Rears need to be taller. As you know, 205/50-15 and 225/45-15 Hoosier A-6's are the same diameter. Good luck!
