So I have my stock 19"s in storage and I have a set of 2005 350z 17" on the car as my winter set. My brother wants to dyno his RSX this weekend and asked if I'd be interested. Would my winter setup have an effect on dyno #'s if I run a baseline dyno w/ my winter rims?
2005 G35c 6mt
Thanks!

 

they'll be lighter, so you'll see slightly higher numbers than with the 19's..

But it's only a ~5whp difference
