Hahaha, no it wasn't Chris but good guess though!
Good job with those cars - breaking lap records consistently can't be bad.
I've been pretty lucky with my wheels, but I generally use Prolines. I gather that Spoke wheels can give you more steering, but it's very time consuming experimenting with the different inserts/tyres/wheel combinations. I generally find one type of wheel I know works and stick with it.
