1) larger wheels are heavier = more rotational mass = slower

For instance, I currently am running some 18" Corvette wheels in the rear, and a shorter tire. It basically fudges my gear ratio to somewhere around a 3.64 ("lower gear", numerically higher) up from a 3.27 stock. All my "race" wheels together, weigh about 75 lbs lighter than my stock 20" wheels. If I put my stock wheels back on, the 0-60 is about .5 sec slower. Lightest, smallest wheels and tires possible = better acceleration than big heavy wheels and tires.
Btw... Just finished my water/meth injection install with a retune... Still with my race wheels on obviously. I'll put the 20"s back on in October. |
Which ECM does the 2.0t use ? are you using hp tuners for your tuning ?
