I'm looking to buy one too.
I was told that for a all out race car, that you need the 66 durometer rubber. Can someone explain the difference between the 40 durometer rubber and the 66 durometer rubber.
Also do you want the steel hub or the alum hub.

Yes I agree I paid $330 shipped for my ati balancer and is worth the extra coin for the insurance reasons since its a street strip car and sees more racing then street. Guess I will do the string method for the belt

Rene the higher durometer will withstand higher rpm then the softer 40 will... That's a large portion of the reason for the higher durometer, and the accelleration rate also has something to do with it, Kurt explained this once before alot better then I can but the stiffer one is needed.
As for the alum vs steel hub, I can not say. The alum will of course be lighter, maybe not as strong for cases where there's other items bolted to the balancer like magnet wheels, mandrel's for other accy's like vac pump's, fuel pump's, etc?
If Kurt sees this and posts up I'm sure he will be able to explain that as well.

they said if your going to be taking the dampner on and off frequently then go w/ the steel hub, if not then you can go w/ the alum, and so i went w/ the alum hub

I'll call ATI next week. I had a 25% underdrive on my old 382 (don't know the brand), but on this new 418, I'm going with a 10% or whatever ATI recommends.
