Which kit?

Depends on what you mean and what kind of racing you're talking about.
OK, your engine is complete and at a fixed power level.
If you're talking about drag racing then you're talking quicker (e.t.) rather than faster (mph). You need to concentrate on getting your existing power to the ground. That means chassis and suspension work will have much more benefit than taking 20 pounds out of your car.
Someone earlier said 20 lbs. is 2 tenths. Actually, I think it would be closer to 2 hundredths rather than 2 tenths.
Take that $500 and put it into your suspension and get your chassis working effectively and you'll be better off IMO.

I see what your saying and yes I mean Quicker not Faster. That 20 pounds if im correct of unsprung weight, is like taking 20 pounds from the drive shaft or lighter wheels or something of that sort no? I believe I posted something in a Topic about lighter Drive Shaft that said 1 pound of Unsprung weight is Equal to 10 pounds of Sprung. so that would make it worth more no? Also 20 Pounds is not .2 it would be .02 off seeing as 100 pounds is .10 off correct?


And what would You Suggest I do to my Suspension that I might not Already have spent money on?
