I'm just wondering why they are running 17'' SSR comps? on the realtime type R's

isn't 15'' faster?

15" rims, faster. 17" rims+big brakes=faster track times

 

They are allowed to change the final drive when they change the rim size. It is usually used in wet versus dry conditions and depending on the track layout.

i dont think they even run the 15s anymore....

 

in speedvision touring car class, you can only run 15"or 17".

 

The Realtime ITRs used to run 16" TE37s (Fred Meyer still uses 16" TE37 rims...I'm not sure why). The Speed Touring Cars are required to use Toyo T1-S tires (the official sponsor) now. The engineer from Realtime said that the T1-S's didn't handle well enough for the drivers, so they had to move to a 17" rim to improve handling. In a 17" rim, the SSR's are lighter than the Volks, which is why they changed rims. I don't remember what kind of tires they used to run with the 16" Volks.

It's too bad that Toyo won't let the cars use their RA-1 tires. Those are much better for the track than street-performance T1-S's. However, it's all about marketing...Toyo wants to promote the new T1-S, so the race cars have to run on street tires.

The Realtime Racing web site says that the cars used to race on BFGoodrich G-Force tires.

Can ya fit a brembo brake kit under our 15's...theres your answer i beleive

 

They run a weird 17" size too. 225/45-17. I guess they need the shorter side walls too to get some better handling out of the T1-S tires. I wonder what that did to the gearing too....
