quarter master street friendly clutch
So who's going to be the first to try this? Over the last few years I've read good and bad experiences for just about every full size street clutch available for the c5/c6 with no consensus as to which one is ideal. This one seems to be well done and not undersize, which can be a pain in the *** for a street car. Looks similar to a proper race clutch, but larger diameter. Well designed with weight reduction and strength in mind.

I don't see anything about street friendly. In order to be a DD it needs to have some weight but it appears this one only offers more power handling ability considering the starter ring gear is mounted with a skeleton arrangement and not a flywheel.
Although the clutch engagement may be less heavy and somewhat smoother, the real problem lies in no mass for engine smoothness when applying a load. This is especially difficult with almost all aftermarket camshafts.

I think the best street/track compromise clutch is the RPS Twin Carbon Billet (~25lbs incl flywheel). It can be slipped and is still light. I have one for sale b/c I swapped to a 7.25" which is a bit trickier with a tire trailer in tow.

C5Z clutch with an aluminum flywheel? I used to run an RPS twin clutch in my gto and it was a great clutch.

Most (probably all) factory clutch setups are really heavy. Probably mostly because of cost. The covers are all formed steel and need to be rigid to allow the spring to compress and free up the clutch disk. Using thicker steel is less expensive than doing the engineering to optimize the shape and lessen weight/material. The friction surface is typically a very thick cast iron piece. Flywheel is the same.

Heavier clutch components allow for smoother engagement and take-off. It's all about customer wants/demands in their perception of clutch feel. If you think they're just throwing cost and weight at every single vehicle off the line just because the engineers don't want to take the time to do their jobs, you're nuts.

If you're looking for street/track clutch packages that still shed some weight you might want to take a look at the Mantic clutches that East Coast Super Charging has available. We haven't run any of the Mantic clutches in our own personal cars at this point, but after hearing about the success that ECS has had with them anyone looking for a nice dual use street/track clutch should definitely keep Mantic in mind.
