No issues with I84 traffic during my 104 mile commute.

Don't forget to mention driving down to Englishtown, making bunch of 10-second passes, and turning around driving home on your normal street tires!

Hi John - sorry to hear you're in need of a clutch. I went from stock Z06 to RPS carbon carbon now I have the Mantic 9000. I'll give you my thoughts on RPS and Mantic. You're free to shoot me a PM if you have more questions and we can connect by phone, if that helps.

Cliff notes - I like the Mantic 9000 better than the RPS carbon carbon for my style of driving and my power levels.

Briefly - my car is 1000+ rwhp / 1000+ rwtq. Weather permitting, I daily drive my car (errands, too/from work, putting around town with my 10 yo son, stop and go traffic) but I also seize ever opportunity for spirited runs on Mexican roads and have tracked the car but not as much as I'd like to have. With my car's power, I have to have a clutch that can hold the power consistently and reliably, but I also have to be able to slip the clutch for smooth take off in traffic.

RPS definitely was an improvement from stock in terms of holding power. I had the RPS for about 2 years. However, two persistent negatives had me looking for other options, which ultimately lead me to Mantic. First, the clutch engagement / clutch pedal travel was never ideal for my type of driving as described above. I would grab almost immediately from the floor. Clutch pedal feel also was much stiffer than the stock pedal feel. After awhile in stop and go traffic, my left calf muscle would be feeling like I'd worked it out. Also, the clutch did NOT like to be slipped. It had a much more on/off engagement, which, again, definitely was not fun in traffic. IMO, RPS is a good clutch, just not the best choice for me.

I now have the Mantic 9000 with non-sprung discs in order to handle my power levels. I've put on about 500 miles. What an incredible difference! The first thing I noticed was the pedal feel. While I've not driven a stock clutch in a long time, I was immediately reminded of the stock pedal feel in terms of the light pedal pressure. Also, the clutch engages right where the stock clutch engages. Very user friendly. Just incredible. Next, thank the lord, I can slip this clutch with ease. It's made a world of difference in the daily driving aspect of my use of the car. Also, this clutch holds the power like no other! I recently ran with BamBam in Mexico and the clutch took a beating without breaking a sweat Because my discs are non-sprung, there is a tiny bit of clutch chatter on cold start up, but after the car gets warmed up, everything quiets down to RPS / stock noise levels.

A lot of words to get back to the cliff notes, Mantic all the way! The only other clutch I would contemplate is the Tilton clutch that Nick Yoskin recently installed in his monster of a car. However, that clutch is $6000+. Wayyyyyy too rich for my blood.

Hope this helps and, again, feel free to ask any questions I may not have answered.

Best of luck!

John

Sorry op didn't want to hijack your thread. Trying to help us get as much info as possible.

Not everyone focuses solely on 60' times, many people just want a clutch that works great and drives like stock. Plus we have not focused on drilling 60' times from this clutch yet, so the jury is still out on it from our perspective. The slip capabilities of the clutch leads towards nice launching without breaking parts while doing so.

60' times like 1.3's require the willingness to break your car, simple as that. How many rears have you been threw Gary? 4-6-more? Axles-shafts-carriers, etc etc etc?
Less then 1% of the people we do business with are willing to do that for a 60' time to brag about, if they are their car is usually an auto, much faster, consistent, and winning races.

It looks like it will stay that way for a week or two then it will be back to a six speed again.
The car did not win the event, but I bet it was the fastest car with NAV, AC and heated seats there.
(The winner was a fox body Mustang with an LS engine)

We just have had better feed back from the Mantic line.
