They are the ****. If you don't have one, buy one! Some ppl say it makes the car's rear end come out at high speed turns, but I did some spirited driving to day and the car felt very stable. I do have good rubber on my wheels though.....I feel a huge differance in turning responsiveness and stability.

 

hows the install on it?

 

It was a *****. I sold mine because it was too much work for a DIY. I'm sure it helps a whole lot.

 

Dude, really? I suck at DIY stuff, and I was able to install my Progress RSB without much problem.
