Drove the First LS9 clutch equipped F-body

**9T8W66** · 12-24-2010, 05:42 AM

Did an evaluation test drive of my Car with the Katech LS9X Twin Disc Clutch.
Everything works flawlessly, Clutch engagement is smooth pedal is slightly stiffer and the Clutch grabs almost right off the floor, except for those 2 things I couldn't tell they changed anything. 800 ftlbs capacity and drives like stock.

Interesting. So do you like the grab point or are you gonna try to adjust it?

**bberretta** · 12-24-2010, 09:31 PM

What master and slave cyl are you using?

I have a LS7 myself, but the LS9 would be sick! Any pics of what it looks like and what Master?

Uses a stock master with an aftermarket slave, but still required a bellhousing spacer for it all to fit. I'm assuming the clutch grab point will change as it's broken in but if not I will probably look into an adjustable Master. I only drove it for about 20 min the other day and won't pick it up till Tuesday after Christmas. The cost has not been finalized since the F-body unit required more parts then the other models.

heres a pic

I believe a complete LS9 clutch kit can be had for around $1400.

Not bad when you consider you could go through two $700-$800 aftermarket clutches instead of buying one LS9 setup.

I believe that $1400 buys just the flywheel clutch packs and pressure plate. Different cars require some different parts. The f-body needed a different (smaller) slave cylinder and yet still needed a bellhousing spacer for it all to fit. Also with the spacer the input shaft sits out of the stock pilot bearing, they fixed this with a C6 pilot that is longer and sticks out of the crank. They were also working on a C5 kit that uses different parts aswell.
Jason will likely put a post up over on Tech with complete specs and pricing.

That's getting into the price range of a Textralia...

The Spec Stage 3+ offers the same torque rating just about; 850 ft-lbs and is a lot cheaper than $1400 for everything.

I do like that it's a full contact surface.

I wonder how well it will hold up to high RPM dumps.
