These are V3 bolt-on 20mm front and rear, the car felt a little sluggish after I had them installed. However, the car did handle better and felt better, but again, they are heavy.
I know some disagree and claim they can't tell the difference, I can, especially coming out of turns. The experts claim that 1 lb added to your wheel is equivalent to adding about 20lbs to the car's total weight, the total of 8.5 lbs would be around 170lbs added to the car's total weight, sort of like riding with a passenger, which everyone would probably agree that makes a big difference.
