It depends on how you use the car. I love my spec mini twin. Great for weekend warrior, strip car, road race, etc. I wouldn't recommend it for a daily because it's just plain small and will burn out quicker. But they are rebuildable and fairly cheap.

At high rpm it shifts flawlessly. My ls7 clutch also ate up my 3rd. And made the car slower.

Are you on the 4th clutch in your car?

Heavy clutches will tear up sycros.....gm uses absurdly heavy clutche/fly combos. To put this in even more perspective for you a termi came with a aluminum fly wheel from the factory. Most mustang clutch/fly combos are around 40lb.

Now i like qtr master stuff alot. My whole set up is qtr master except the cage is tilton. I've put over 40k miles on it......mostly with used discs from our race car when i worked on the race team. Last time i bought a set of discs and plates was several years ago. It only costs about $400 to renew a clutch like this.

Mine is very streetable.....probably more so than hammers because my master is smaller than his.

So by this logic manufacturers setup clutch/flywheel/trans combos for failure?......So they can replace sycros?..... under warranty?......for fun?

Yea i guess so. Gm fixed my trans and several of my buddies under warranty. Ever hear of empty82??...lol. From my results and hammers light clutches. ....well real clutches shift better especially at high rpm.

One thing for sure if gm was to worried about it they would not have put the notoriously weak ls1 clutch in fcars and there are 2 people in this thread that said a heavy *** ls7 clutch helped them wipe out syncros. Now with that saud the ls7 stuff is heavier than the oe fcar clutch......so yea weight seens to for sure have something to do with it.

Roasted the stock clutch.

Put in ls7 clutch

That one wrecked the Trans.

Put in the spec clutch

Ran it two years.

Refreshed it last winter but it was fine.

Nothing to be upset about i huess

How much mileage on your car?

big hammer

Around 38,000

Nice low mileage car. My shelby almost has that in it.

A few issues here and there combined with specific syncros dying is not indicative of a overall design flaw. If it were truly just because of the weight of the assembly, then it would be much more rampant and it would not choose what syncros it damages.

They went to triple cone syncros for a reason....
I did away with my syncro and to shift it the way i do the heavy clutches would likely tear mine up the way it is now.

As far as choosing which syncros it damages yes it would be indiscriminate. .....other than some syncros get abused more than others. Not many power shift 5/6 and you can't do 1st. So that only leaves 2/3/4.....which does seem to get tore up.

There is no reason at all for gm clutches to be as heavy as they are.

Is it low because you live your life a 1/4 mile at a time?

Except for drive-ability, and NVH.

islander033

Not really, this is canadia lots of days of winter and **** weather.

I had a vert once, had the top down 2 times in 1 summer. lol

Again. ....no one has a problem wuth 1/2 the cylinders and 1/2 the clutch weight with drivability of a honda. No one complains about the drivability of a 40lb ford clutch.

I noticed no significant change in nvh in my car with a light clutch. I did notice and appreciated improved throttle response

Do you read what you type, before you hit submit?

1/2 the cylinders.....1/2 the clutch weight = Stock Gm Clutch weight.....

Also, Again... Comparing a Honda Cvic to an Fbody is like comparing Apples to chicken nuggets. Completely different vehicle weights, not to mention totally different gearing.

WisT02ws6

I live in Wisconsin, so I feel you lol.

I read it fine......i also understand that not only are they 1/2 the cylinders , 1/2 the clutch they are over 2/3s the weight and 1/3 or less the motor with no where near the tq at idle/light throttle.

I guess you ignored the v8 mustang comparison. ....maybe you should read and then try to comprehend a bit more. We're not talking about people that want to keep perfectly stock cars here. Lets face it about any thing you do to modify a car can reduce streetability is someones eyes.

I can understand your point on gearing but anyone looking for more performance probably has more gear in mind. Most of gm stick cars are under geared.

There is no reason to have gm clutches weigh what they do.


You and i have had this conversation before.

His car has an LS6 swap Mappy
