i drive real aggressively and i myself feel teh difference. that's all i can say about it. i can feel all 4 tires grip the road and screech like never before. maybe that other person hasnt really pushed his VX 'cause that's probably the only way you'll feel teh difference. like i said, after i invest in a set of 20's i'll let you kno how much better it is. =)

also...i had it torqued to the max lbs...so maybe that's also the reason. personally i think it's a good improvement from stock 'cause i pretty much push my VX to the max most of the time.
