in the track more rubber is better~!!!!! i plan to go 15/16 on my exige it comes standard with 16/17

 

I was hoping to go 18s for track use but after seeking the advice of a couple experienced track people on this forum, I realised that maintaining load ratings at the rear of the car is important and nothing under a 335 rear (in an 18") will give a 102 load and these won't fit (GT3, not RS)... As i'm not prepared to roll guards etc to fit them, I'm gonna stick with 19's and OEM sizes or a little wider up front... Don't want rear blow outs, i'll have my work cut out for me staying on the track as is...
