as above fellas , i want to get some ns2r or fedederal track style tyres for my car

i dont mind arch trimming

 

I'd be more worried about the tyre touching the spring cup,unless your running coilovers?
what size wheel do you have on at the minute ?

 

Jeff spring cups are modded aready mate
Adjutable rear beam too
Wheels are 8 x18 et35 comp th

 

bump,anyone

 

Have run 235/40/18 on the rear for many years but stick with 215/40/17 on the front its a great combo. On Topspeed runs I squeeze on 225/40/19 at the back which can only be used in a straight line & they rub on the Bruntingthorpe bend. Fully trimmed arches. Don't go big on the front it will effect the way it handles & steers. Oh yes it has coilovers.

 

thanks for the advice rod ,but i will stick to the same size wheels as i have them already.

i dont think i will be doing any topspeed runs lol

 

Paul Thatcher runs 225/40/18 on the back of his Saph and doesn't have any problems, I think he uses a 215/40/18 on the front though.
