I have two options to go with and wanted to know what you all though would yield the best results at the track. I've made about 5 runs on 17'' ZR-1s with GY F1 285/40 size and had a 2.17 60'.

My other option is to run the stock wheels with 245/50 size GY GSC's.

Which do you think would hook better? I know the 16's have a lot less width but I'm thinking the larger sidewall might be better.

 

No ideas huh? Not looking for expert calculations, just opinions.

 

f1 get my vote

 

Well, I'll bring both. If I run like crap on the GSC's, I'll switch back to the F1's. I wish I could just bolt on some DR's!
