I wanted my damper to actually dampen... so I went with an ATI super damper. At the time I was still running HPDEs w/ my Z06 so I wanted a top of the line part. It wasn't cheap at $440, but 11,000 miles later I still have zero pulley wobble and the motor is smoother than before my cam swap.

I'm assuming any aftermarket pulley is lighter than the stock one right?

Ive got the ASP, uses 1 belt for everything.

Get 2 though, it might fly off (mine came off about 3 times in first year but hasnt jumped off in the last 2 years using same belt).

I am curious about the alt. pulley also... Does it make a significant increase in hp when putting on both the underdrive pulley and underdrive alt. pulley as opposed to just an underdrive pulley? I dont have an aftermarket stereo set up and I am running an M6 so I would assume the Alt. pulley would be worth it as well right?

Yes it does. If you order the SLP pulley from us, you can add the 2 belts for 46.00 (they are not listed on our web site but you can call us to order them).

Thanks!
