Since I don't want to be the laughing stock in the class I'll be placed in (QM I believe, Street Modified)
I figure I will have to step up to the plate and get a second set of rims and tires for auto-x (time trialing sooner or later...okay, much later) car has stock fenders, I do not want to add flares, but I am open to the idea of rolling the fenders or pulling/bumping them out slightly Current rims are 16x7 under stock fenders running 205/45/16's (40mm offset rims) |

I think two big factors to consider are (a) do you have stock gears? and (b) what kind of gearing do you need for the typical course layouts you will encounter?
Obviously you want to go as wide & sticky as allowed by your car's body and the rulebook. But going shorter/taller will have a significant gearing effect. The "gears" spreadsheet is very useful to play around with speed-in-gear and shiftpoint scenarios. |
