Any interest in a full BN Sports kit. Same as this except it includes the door mouldings to beef out the sides a bit to meet the kit.

13 x 10, You can get a 225 or 235 tyre in 13's that will be plenty wide with trackday tyres might even be a bit overkill if you ask me. Its your cheapest option if on a budget pity they dont do them in 14's or 15's tho. Getting anyway wide wheels from japland will be big big bucks new or 2nd hand.
