20" Wheels = Lost Speed?

Guys think you are cool, girls think you wasted your money..[less to spend on them]......bigger wheels don't correlate with big human body parts usually the converse.

Sounds like you are leaning toward 20s. Get them. Any performance loss is going to be small (I have lighter 3 piece 20s myself and don't notice a difference). Besides, do you really drive around full throttle all the time? My car spends more time parked at stoplights than it does wide f***ing open. How about yours?

My 19s are light for 19s and I still noticed my car got much slower.
It feels like I have 2 people in the car and a trunk load of autox gear.

No, all 4 wheels need to be included in the factor, unless your car wheelstands when launching. Seriously though, the car has to accelerate all 4 wheels up to speed, both linerly and rotationaly so all 4 wheels count in rotating mass.

It all depends on how much looks matter to you over performance. 20's do look way better than 19's IMO and my car is fast enough for now, until I can afford some iForged 20's. Then the best of both worlds can be enjoyed!

Same deal. Drive to work and back. That's all.
