Im in the process of installing a TCI line lock for my FB. Since its hard to find a fitting to mate metric to standard, Im going to run new hard brake lines (metric in one end AND standard on the other end). I made plans on where to mount it etc etc, but I noticed that the driver side of FB hard brake line has loops in it (unlike the passenger side, its loopless).

I've done many brake jobs but Im not sure if it will make a difference if I dont follow the original brake design.

thanks

Nice RX3 if the one in your avatar is yours looks great

The hurst racing version has dual inputs and outputs. I ran it in my TII and liked it.

Proporting valves set proportion, but are never adjustable down to zero proportion; that's not how they work.

Aswell, with your method, you would still have to step on the brakes to activate the front brakes.... almost negating the purpose of line-lock. See below.

Well its handy for that, that is not its primary purpose.
Line-lock, also referred to as roll control, allows you to lock on your front brakes while staging. This way, you can slip your clutch and preload the entire drivetrain without rolling forward. This saves inital shock to the drivetrain, which is not only stressful on parts, but also usually results in spinning tires. This preloading works better when you don't have the rear brakes activated.

You can do something similar by merely stepping on the brakes with your heel and then modulating the gas pedal with your toe... but its hard to master. Controlling the front brakes offers far easier gas modulation for launch.

Now... this form of launches is very effective... as you can tell, the typical "rev-it-up and dump the clutch" method used so commonly by the forum members doesn't exactly result in great 60-foot times, due to bogging the engine. Launches aren't just important in drag racing, they can make or break your time during autocross.

To make this system REALLY consistent for launches, intall a brake pressure gauge (ever wondered why someone would want to use that gauge?), as you don't need to apply full brake pressure before activating the line-lock.

I really liked how I was able to launch my car using this system of launches. I found it very consistent, and resulted in being able to modulate launches to maintain the car at a relatively constant rpm (my estimated torque peak) until the clutch was let all the way out.

yes, its my other rx.

thanks

Maybe his car is stick and he doesn't have 3 feet
I see what your saying tho shut off the back line so that when you hit the brakes with the switch on it just does the front but this would be a problem if he had to work the clutch and gas too
