I see that there is now a ZR1 Clutch and flywheel for the C5 flywheel bolt pattern. Is anyone running this in their car. I'm interested in hearing some input.

Thanks in advance,

Look into the lt1(C7) clutch from monster for a factory style option.

I would be curious about the ZR1 clutch. I will say Ive driven a car with the Mcleod RST and it feels almost like stock for up to 800hp and uses all factory hydraulic parts. My RXT feels the same it just can get a bit more grab to it.

What is your set up John?

I have a 404 with a Vortech. 675ish rwhp. I did some research and a better option for me is the RPS Street Twin Full Carbon clutch which utilizes the factory hydraulics. The ZR1 clutch has tons of hydraulic issues on the C5.

I also have the RPS twin carbon clutch and its great, much better than stock and no harsh pedal like several other clutch setups I've tried. (My HP is considerably lower however at 525 rwhp)

Typically, the clutch disc material is what gives it that on/off feel, or not. Factory clutches are usually organic compound, and aftermarket disc are usually metallic. The metallic discs, will usually give it that ON/OFF abrupt feel. A carbon disc, is the way to go to have a near(or better) than stock engagement. If you an organic(stock style) clutch will work for you, power wise, you'll be fine. If you're making power, and want good feel and longevity,..and probably the ability to rebuild, go with a carbon disc.

Just something I have learned from running probably 7 different aftermarket clutch setups in my C5, not to mention the ones I have installed for peoples. That said, the ZR1 clutch in our ZR1 seems to hold up well under spirited driving. We have not taken it to a drag strip though.
