Thanks for information! Was thinking of tire size changes after this Saturday's abysmal showing of 8th in a field of 12...first five were RS, RS, RS, Type R, RS, Mini... Anyhow... Was thinking of stock rims in front (with spacers) running 255/35-19F and 275/30-19R. Crazy right? Desperate to fix the understeer...it is slowing me down big time. I will look into your smaller/lighter wheel suggestion. Thanks again!
