Sure no problem, with the 19's I just felt that I had lost a bit of handling and performance due to the larger wheel compare to the 18" Rays. With the beacons on my doorstep I usually go for a good drive and I just felt that I got along with the car set up better on the 18" Rays.
Up until now I had being doing mods that would save weight and squeeze any extra hp from the car such as the MD system, ART pipes, Plenum spacer, velocity stack, UPREV etc and so now it makes sense for me to go for a light weight 18".
The traction however is amazing with the 19" pilot sports and look incredible.
I did put a post on this forum asking if anyone noticed the difference going to 19"s and the majority said that they didn't notice any difference. But I'm one of those people that any tiny little difference will bug me aha.
Im probably going for the Enkei RPF1 which is one of the lightest 18"s but don't look no where near as good as the ES2.
