How heavy are those 18" rims? I have a theory that heavy rims will make a BIG difference. Shoot, when I go from my stock wheels (22lbs each) to my summer wheels (16lbs each) I notice a HUGE difference! Car is MUCH faster with the summer wheels! Keep in mind my summer and winter wheels are both 15", the weight savings alone makes a difference.


one pound on the wheel acts as if there was four pounds in a seat.

so we take your 22-16 get 6

6 x 4 = 24
24 x 4 = 96lbs.

for every 100lbs you gain you lose roughly 10hp in speed.

so there is probly a 10hp difference. Which is a noticable gain or loss.
