Line lock question Will a line lock save wear on a clutch? In other words, rather than feathering the clutch, is it better to run a line lock, let the clutch out (tire start to spin) then launch by releasing the lock?

Actually, a line lock can help the clutch as well as the driveline and brakes. If you're footbraking to start heating up your tires, your putting a greater load on the drivetrain and clutch. You're heating your rear rotors/pads up quite a bit and wearing the components quicker. You also risk the likelyhood of overheating and warping the rotor and clutch plate creating excessive runnout/chatter.
Now if you're not footbraking, then its not going to effect your driveline or tranny as much, but your also not going to have a very controlled burn-out heating up the tires. For the cost, our line locks are worth every penny. We've got a few styles to consider, our b001 kits are the best bang for the buck. All kits are in stock 24 and ship within 24 hours of payment during business days.

power brakin has no ill effect on clutch life as long as it's in good shape to begin with, whether you hold it with your foot or with a line lock it's the same thing....the benefit of the line lock is you dont beat your rear brakes up

Verdad Gallardo I disagree. When you step on your brakes and forcefully overcome the rear-brakes, you are stressing your clutch, and drivetrain to a higher degree. You not only have to overcome static friction between the tires and road, you have to overcome the friction of your rear-brakes being applied before you can even try to make your tires spin. The increased force needed can result in shortened clutch life as well as other components.
When you use a line lock, you do not use your rear brakes at all. You are to a much lessor degress stressing the clutch and drivetrain. Using a line lock, you are not trying to overcome the additional stress of rear-brake clamping force.

it's not like your standin on the brakes, just enough to keep the car still...after the initial spin, the clutch is no more stressed out than than shiftin down the track, most tracks have water boxes so the initial stress to rotate the tires is greatly reduced
I'm not going to argue with you, when the brakes are applied on the rear, you have additional stress that is applied on the drivetrain. If you don't step on the brakes enough, your going to move foward quite a bit.
Overcoming the initial stress is substantually greater. Even after you get passed static friction into kinetic, there is still a higher load when your on your brakes.
You are increasing the stress on the driveline and clutch just as like towing a car stresses the driveline more due to increased load, same situation is applied.

I must say I agree with Steve on the point he is making. Footbraking will cause more heat caused by friction in the clutch thus shortening it's life and also burning up a perfectly good set of brakes. But the way he thought to use the line lock is wrong. The only thing this will do is let him sit at the tree and smoke the tires while the guy in the other lane is putting bus lengths on him.
