So I decided to go with the 20" Axis Pentas, just love the lip and look of them, but I got one question. How big of a difference will it be going to the 20" from my OEM 18" Sport wheels, handling and acceleration wise? Is it noticable/worth it? Thanks! -matt

 

your acceleration will suffer somewhat, but not enough to warrant not getting the wheels. The Penta's are great looking wheels, i'd say its definitely worth it!

With my cheapo cast Privat Netz....I noticed a huge difference in acceleration from the OEM 17s to the 20s. I'm not sure how much a difference it was from the OEM forged 19" I ran prior to the Netz (sold 19s, put on stock 17s)...but I felt it big time going from the 17s to 20s.

As Gdup said...I still wouldn't have not got them even if I knew

 

Very nice choice.

The average equations are anywhere from 4-8lbs of equivalent car weight when you add 1lb of unspring weight. So if you use those every lb more the wheels weigh would be like adding 16-32lbs to your car.

I know when I got rid of my first 20" wheels that weighed 14lbs each more than my new ones the difference in acceleration, cornering and braking was very noticeable.
