Default Spec Stg 5 :(

Just wanted everyone to know my expirience I had with the Spec 5. I installed her, put about 500 miles of daily driving on her.... never over 75 mph, no dumping etc. Went to the track and made 8 passes launching at about 2500-3000 RPM. Got home... clutch was slipping bad. I read a post somewhere where the individual stated a similar case, he then said he removed the spacer and all was well. Hoping for the same results I dropped my tranny and sure enough the clutch was in fine shape .... except for one thing. The clutch disk itself had several hair line fractures.... about 10 in all. I just replaced it with the Tex twin. Watch those 5s' boys.... could cut your legs off!!!!

i have had problems with ram clutches like that. i have had great luck with the spec st3 +. it's the only clutch that has lasted for me. did you call spec? do you know what caused it to go so soon?

I've no idea, I can only speculate. Here nor there, I've gone with the Tex Twin.

Please let me know how the Exo skel does, the clutch is the last thing for me to buy to go full boost! Thanks man, I might bother you by PMs next week or so if you'll have some results?

Sounds like you had the shim in there.90% of the time you can not run the shim with the 5's.If you do,it will slip,wear fast and crack from serious slipping/heat(like most clutches do)

I wish I knew the shim was optional.... I was told to put it in, it came with the kit. I called and was told to install it. Really sucks.... lesson learned.

my understanding is that many of those race clutches were never meant to be daily driven. most of the high end road race stuff will not endure many starts as they don't like to be slipped. even if thier design is rated for extreemely high specific outputs. perhaps this may be the case in many instances where we try and over clutch a street application. just a thought

Thats any clutch with a ceramic based disc, they dont like the street.

Thats right. Alot of people think they can buy a high HP race clutch,daily drive it and last forever. Doesn't happen.Sure some people get alot of miles but they are most likely the people that don't slip it.
Another common problem is improper installation/setup.Everybody vitches about SPEC's failing early but I've never seen them fail early and we do a ton of them on anything from DD's to seriously beat track cars. They do fail within time but it is expected with the way they are driven in those situations.

SPEC told me to run the spacer as well and had similar results with my SPEC 3+. We got to it and took out the shim and everything sems fine so far- 3,000 miles on it since. I think I will only buy partsnow from sponsors that have good customer service.
