toyo's get no mention?

 

I've driven a Z with Toyos T1S's extensively Definatly a good tire... I think to see a real difference one would have to go to Toyo RA-1 which of course they don't make in 19"

 

SO-3's on a road course are just ok but once they heat up they get a little greasy and are just an avg tire. You are better off getting a R compound tire like others have mentioned RA-1 or if you want both street and race then go with Pilot Sports cups which is great tire ( just limited sizes) but it is R compound.

I have Ps2's and I think they are overall a better street tire than the S0-3s and def more quiet and much smoother for sure with better or equal grip.

 

I'll just have to get some 18"'s and some g-Force KD's / RA-1 / or Cups....

Two sets of wheels that's the solution!
