I am very concerned about wheel spin since it is an open diff and I have the extra power from the Dinan performance upgrades. The extra rubber on the road will help. Sort of a trade-off. Looks wise the 20's will look great as these are the new HRE SC (Super Concave). They will look very deep. They are also a very lightweight forged wheel so performance difference should be minimal. Overall, I have more HP and a lot more torque (with the install of the new diff) so I am still going to see big gains over stock setup. Pretty much all of that will be substantially offset. Ride will certainly not be as good as the 19's, HOWEVER, I also have Dinan suspension and believe it or not it actually rides SMOOTHER than the stock sport suspension but eliminates almost all roll and bites very hard in the turns. I really think that I am going to be just fine. Wheels and tires are almost an $8K investment so I did consider all options very carefully. I did not want to get the 19's and think they were smaller than I wanted. I have seen the 20" P43SC on a 335 and they looked stunning. I am sure with my drop they will look pretty much perfect.

I agree on 20's, I just mounted 20's a few days ago and to be honest, they feel a bit more comfortable than my stock 172's ! as far as performance goes, it does feel heavier thank stock but, it's all worth it! I've been getting nuttin but compliments.
