I have a SPEC Stage III Carbon. I regret never buying a McLeod Street Twin.

My FIRST Stage III carbon, I took out at 10k miles for non-clutch related issues. Low and behold, the disc was worn to hell and back (totally worn out, though it still gripped), and the PP and flywheel was starting to get torn up by the worn out disc. And one of the disc springs fell out when I was pulling the disc; the metal retainer broke.

SPEC of course blamed the spring on the pilot bearing (which was fine), since that is their standard line. They totally ignored the wear issue (10k miles, not too much track use). Their offer: they would resurface my PP for free (plus me paying shipping), and sell me a new "updated" disc for $100 plus shipping. Friend of mine was having all sorts of drivetrain issues, and just gave me a spare Stage III Carbon setup he had, which is curretly working in my car.

In the end, it is very streetable, but I really wish I had purchased a Street Twin from the start.

 

yea that street twin is just tooo much money and i just dont feel cunfy having all that weight sitting on the back of the engine and on the input shaft like that!!!

ive heard a lot about the old SPEC setups but people said that their new **** is working good so i dunno

 

The Street Twin isn't an uneconomical choice IMO when you look at VALUE. You get a more durable flywheel, a master cylinder that works better and a clutch disk set up that seems to last at least twice as long as other clutches -- all for $400 extra dollars over the SPEC. And when you eventually do wear out the street twin, they will refurbish the whole thing for something like $350 (or less -- I can't remember the exact amount). I chose the Street Twin because it wasn't necessarily the cheapest choice, but it was the most economical based on lots of others' experiences. You know its going to hold and be streetable, and while people grumble about the weight, I've never heard of someone's car slowing down after intalling one.
