My previous clutch was an RPS stage 3 with stock flywheel and unsprung disc. While I liked it, it is not a daily driver friendly clutch. It all depends on how much you drive your car and what you do with it. When new, it is pretty hard to get used to since you are used to a full face trd disc. The stage 3 also gets really mixed reviews on reliability and longevity. Mine lasted about 25k miles with heavy driving. My car is not my daily driver so most of the time it was out and about cruising or drag racing.
I can already tell you that the week I had the RPS c/c in, I love it. For a twin disc, it engages much smoother than the RPS stage 3 and it doesnt chatter like a john deere. The pedal feel is even lighter than the stage 3 and it will hold much more power and wears better due to the carbon. The C/C comes with everything you need such as bolts, flywheel, tob, pilot bearing, etc. I plan on keeping my car for a long time and have already been through 3 clutches in 7 years and I liked the rebuildable factor of the C/C for 400 bucks.
A single disc clutch with stock flywheel and all needed hardware will usually run you anywhere from 1100-1300 depending on the model you choose.
