Exactly...

The only thing Adrian didn't do there, cuz likely he couldn't, is to actually drive or test the cars w different diameter tires. So he missed the finer details a bit on what happens when you are close to the 5% limit but not tripping the alarm. I go back to the old threads a lot from the early rennlist days. Fantastic source of really good info. Also on pelican. I've got huge volumes of threads printed for when these forums crash and we lose everything. I'm crazy that way.

Anyway . C4 will handle better and be more well behaved when you have equal diameters. When you are close to the 5% limit and not tripping the alarm, you are also closer to torque transfer to the front wheels and the PDAS kicks on earlier. So you basically understeer more...generally speaking. You are also putting stresses on the planetary gear and using the clutch packs more and adding undue wear to the entire system...

I was going to chime in but Mike and Hal covered it already, the wheel size is not the issue but rather the proper tire ratio. OTOH, if the OP prefers to sell his setup to get something he is more comfortable with, someone will get a nice set.

You'll notice on the TireRack site they don't sell the R888 for the C4. They don't come in the right sizes.

I purchased these and don't like the color on my silver car so they are up for sale if someone wants them ... PM me. In Chicago now ...

Have them powder coated satin black and you will be all set.
