Yup it's clutch time and I've kinda narrowed down my options to the two ACT clutches;
MB7-HDSS (506tq/36%+ clamp load, heavy duty)
MB7-XTSS (567tq/54%+ clamp load, Xtreme)
I don't go to the track, but I refuse to be late for work, and I'll take off from the light when properly motivated (rare). Based on my mods can I get a nod on one of these. They use the same organic discs and I'm fine with that. It's their torque ratings I'm wondering about. I'm thinking of going with the heavy duty, but I don't want sell myself short.
I'll be ditching the clutch fluid restrictor thingy too if that makes a difference between the two.
Well, if I'm not mistaken, one is a 2900# PP and the other is 3100#. I had the HDSS, and I think it will hold all the power you'll give it. I did not like mine, but I race frequently, and it's not good for that (notorious for 7k rpm lockout). Mine lasted 9500 miles, and now I have an Exedy 4-puck. My 4-puck is awesome for racing and works fine for daily driving, but I usually don't recommend it to someone who doesn't race. I think the ACT HDSS will work fine for daily driving as long as you don't try to race or drive fast.
...and it's not good for that (notorious for 7k rpm lockout)....
...Mine lasted 9500 miles...
You have to adjust the pedal to the very top just to avoid the lockout problem, but that is uncomfortable for driving/racing, and it led to premature wear in my case. It also kept me from shifting as fast as I like, but that was 100% remedied with my Exedy.
larry...if youre gonna spend 1500 for an exedy single...might as well get a twin for a couple hundred more. who knows what kind of power mods are in your future anyhow hahaha good luck with the purchase/search!
It's pretty rough but definitely grabs. I base this off a buddy of mine who runs 11.7s @ 117+ on his 04 with White Rabbit and meth. He does 4 wheel burnouts at 7k, then launches at 7k with basically a clutch dump and that thing takes the abuse with a smile. Not great for daily driving, though in terms of comfort. I forget, though, is their 6-puck sprung or unsprung? My Exedy 4-puck is sprung, which helps it remain somewhat docile for daily driving.
