What does it do? (such a n00b question I know, sorry!)
helps reduce the roll on the rear of the car, and trust me it works. i have coilovers and once i added this it made such a difference, a must have for anyone with a starlet.
Cheers dude. It looks a bit on the flimsy side imo though. But thats coming from someone with no experience of it so i guess it doesn't really count!
They obviously do the job or people wouldn't fit em!
