Stick car, too much clutch?

My 2 cents,

If you have a big-tired car, chances are you don't need counterweight on your clutch.
Counterweight is great for a small tired, high hp car with limited traction. Low base
pressure gets you off the starting line, counterweight locks it up at the gear change.
If you use the clutch at the gear change, you'll need more pressure to lock the clutch back up, and that usually means the tires will chirp at each gear change.

I usually start with all fresh pieces and turn up the static around 1000lb. Make a run and start backing down the pressure until it slips, then add 1/2 turn. Watch the tack on the starting line. When you let the clutch out, the rpms should not drop then rise. they should load the engine and then rise. Should shift smoothly at each gear change. If it slips into high gear, add counterweight. On a cool day you may need slightly more pressure. Hot days, it may be too aggresive. This is where you need to know your car.
The clutch makes or breaks these cars...

If you have a bearing problem, I suggest checking the bellhousing alignment. If its right, you should have no problem.
