Hey guys, wanted to see what your experience is with respect to the difference in performance between 19/20" wheels. Being that the is250 doesn't have much power, did many of you go with 19"s rather than 20"s to save on weight and performance?

 

I went with 19" s with Verde Axis and am happy with the look and handling. I didn't want to risk rubbing with 20"s on 35 and 30 series tires with the RSR Downs or have ultra low profile tires 30 and 25 series to compensate for the larger diameter and impacting the ride further.

With the 19"s no perceptible performance difference.

 

I went with 19s because the car is small and I don't care for the way it looks with 20s, but that's my personal choice. It had nothing to do with the power and, if I had picked up an IS350 instead, I still would have gone with 19s.

 

Thanks for the reply, mind if I ask your tire sizes and did you need camber kits with the RSR down setup?
