Na for track use I wouldent go much stretch at all. Them new wheels are 8inch and am going 165 or 175 just to fit under my arch as them wheels hav et0 😵🔫
Wheels are 15x7 et35 with 25mm spacers on front and 20 on rear. Think the camber is set a -3.5 on the front not to sure there a far bit like tyres r 165/50
Test fit of new wheels needs abit of arch work and alot of stretch
