I have 2 pairs of tyres, same size (205/60 13) that I'll be using at wakefield on the weekend, but they are two 32Rs (soft) and two 48s (medium).
The car is standard height at the back and lowered at the front, some neg camber and understeers like hell.
My question is, how should I distribute the tyres to make the car fastest, ie. 48s on front, back, left side, right side etc?
Or does it really not matter?

cheers
