I have someone selling me one new for $40... What is the benefit if having this and can I install myself????

 

Wow. Nice.

That's an awesome deal. It retails around 160...thus I opted for eBay ($31). It's basically a metal tube that increases efficiency in corner and holds the engine tighter/better. Good cornering, etc. It's better if you combine it with a rear tie or rear strut. But yeah...the ride is a tad stiffer...but reduces fishtail.

I would know...I was stupid and did around a 60 degree turn at 25 mph. Car did not flip...but in my mind it did. :P
