I figured I would give my thoughts on the kit that way there's more information out there.
I went with the clutch and lightweight flywheel combo with the 6 puck sprung disc. I also ordered a ZSpeed HD CSC and an OEM Master cylinder to go with the kit. Everything arrived fast and the kit was complete. Installation was a learning experience for me and fun for my friends taking selfies next to the transmission that needed to go back in my car. One installation note: the Z1 clutch line is not compatible with the Zspeed CSC. you'll need to buy Zspeed's stainless line.
Just for refernence, I daily drive my car and use it at the track. We did all of the work at 60K miles (all original clutch, master, and slave were in use). After being on the system for 6K miles I've observed the following:
- Daily driving requires a different technique. It takes some extra throttle to get the car going since you cant really "slip" it into gear.
- There was a little more chatter, but nothing unbearable. (that being said, i have a tomei exhaust system. take that opinion with a grain of salt)
- On track, the clutch engages with absolute perfection. Absolutely NO slipping. I did have to re-learn how to heel toe with the new flywheel, but that's a fairly easy adjustment.
Overall, I rate this as an excellent product. If I were to rank this on a scale of 1 to 10 with 10 being track and 1 being street, this kit is about a 7.5. The pedal didn't feel very heavy, which is also a plus.
