Default Aluminum pressure plates

Has anyone ran an aluminum pressure plate w/ an aluminum flywheel? What are the pros and cons? any reliability issues?

I see that spec offers an aluminum pressure plate as an upgrade over the iron pressure plate for an extra weight savings of 4-5 lbs.

Normally a friction surface is attached to the plates to do the actual clamping. Less inertia to spin up, what's not to like. I'd also consider a twin disc setup.

I'm not talking about an aluminum flywheel. I'm talking about an aluminum pressure plate.

I have RPS streetlite twin carbon, feels just a little stiffer than stock, and is fine for driving daily. Have to give a little more gas to get going, but not bad at all.

I just had a spec aluim flywheel and pressure plate installed in my C5 ZO6. the pressure plate has an aluim housing but the rest is steel, they said it would save 4-5lbs over a reg pressure plate.

At the same time had LG long tube catless offroad headers and vararam cold air intake and dyno tuned to 409 rwhp.

I was worrying about initial take off being more difficult and requiring more rpm to prevent stalling. It was just the oposite, it wanted to break traction easier and required more backing off of the pedal to gain traction. I am completely happy with the set up.

Do you think it the 4-5 lbs weight savings was worth the $289 upgrade?

Its more a matter of percentage of weight loss on the pressure plate. They said rotating weight is very important to rolling accel & deccel.

I am setting this up for ASP solo class and am using all the equipment put on the last National winning C5 Covette. If it good enough for the current ASP national champ it works for me. (he now competes in a C6 ZO6)
