I think if you have the car flogged out, tuned out and drive it perfectly every time, buy that stuff. I do think it can help over time,but it is never one thing, it is all of the things. If there is no more HP to be had, start there. If you can't make minimum weight and you can save unsprung weight why not?( expensive though) You need the good stuff though. I have heard of guys trying some aluminum spools and the deflection hurt more than any weight savings. If you are not hampered by any pesky performance rules, just hop up the bullet. I agree, very small gains for big money. Walk the Comp pits.mthose guys know.
