StreetSpeed

I'm finally getting ready to pull the trigger on a C6Z primarily for track use. My dad has a 2010 GS and he runs aftermarket reproductions in the stock sizes. I see an 18X11 and 18X13 size looks popular. I assume this is mostly for availability and price of track tires. I intend to run the car this first season on a streetable tire (R888s or RA1s) and switch to slicks once they wear out. I've searched, but can't seem to find the applicable offset to run wheels like this in the C6Z. Also, what tire profiles need to be run with this setup? Any help would be appreciated. See you on the track!

I have run 315R18 and 345R18 rear on 18x11and18x13CCW

Also like stock wheels for cost savings and ran 295's and 345's

You can get Hoosiers for both... Moderate price differences..
OEM wheels are abundant and way cheaper.....CCW's are more favoured by more involved track guys
