Today I installed a Breathless performance short throw shifter. I got everything put together and was excited to go for a ride. During this ride I discover my clutch is slipping primarily going from 2-3 when in it real hard. I'm just curious to what kinda clutch I need to go for. Do I need to upgrade my clutch or go for some kinda factory replacement. Please help me as I am a newbie to the c5 world. My car is a mostly stock 99 FRC.

 

I believe everone is upgrading to the ls7 , someone should chime in .

 

I'd second that motion.. It's tough and kiss..

I installed the LS7 kit from GM Parts House and all was fine.. Be sure to replace the slave cylinder with new.

 

Some TIPs that will help you if you do it your self:

- Install a remote bleeder line!!!

- Replace the pilot bearing.

- Even though the LS7 is an OEM type clutch, MEASURE the slave cylinder to pressure plate clearance!!!!!!!!!!! If you get it wrong, the clutch will slip if the clearance is too tight and will NOT fully engage if the clearance is too large.You may need a shim to correct the clearance. Measure twice, install once!

- Install a new master. Yours is most likely at the end of it useful life.

- When you reassemble the drive train, I always separate the torque tube from the trans/differential and install just the torque tube into the clutch/bell housing by its self. Its a heck of a lot easier and you will have less of a chance of bending the clutch disk or damaging the pilot bearing.

While you have the drive train out, Heres a couple post for differential up-grading. Its an economical way to make the differential a little more bullet proof:

Change out the transmission fluid while the trans is out and install some AMSOIL Torque drive ATF. Its a very good upgrade fluid.

I think I covered it all!

Ls7 for me also, feels great, holds 430rwhp.

 

How difficult is it to replace the pilot bearing? Mine isn't making any noise but I am replacing my cluch in the coming months. Was debating on the pilot bearing...

I had a shop do my last clutch swap and they said it wasn't needed but that was 20,000 hard miles ago

 

AutoZone rents the slide hammer and the inside bearing puller. Heres how i do it.

Use a propane torch and heat up the end of the crank to approx 120 deg. Once its heated, it really helps the bearing to be removed and reinstalled. I also chilled down the new bearing in the freezer.

My 02 ZO6 pilot bearing only had 60K miles on it. It wasn't causing any issues BUT, it wasn't in good shape either. It was DRY and the bearing fell out during removal.

BE CAREFUL with the welsh plug in the end of the crank and do not puncture or dislodge it. You will have a massive oil leak
