If I'm sitting somewhere with some friends and I just want to have one hell of a burn out, is there a way I can transfer all the braking power to the front wheels and take it off the back wheels so I don't burn my brakes up (and also a better burnout)? I know this might be possible with an adjustable proportioning valve, but I didn't know just how adjustable those are. I also take it that the stock valve won't allow changing this at all, correct?

Its not like I'd drive around like this, just purely for show from time to time.

line lock.

you depress the brakes, it has a noid that keeps the line pressure in teh front, the releases the rear pressure. wa-la, front brakes locked, rears not grabbing. just apply power

could you also use an adjustabe PV? I was thinking of installing one, but instead of putting it in the engine bay, have it somehow be inside the car, that way i could adjust as I'm racing. Does this seem like it woould be a good idea, or is it even possible? I figure as a race goes on, the brakes will fade, and you might want t oadjust the bias, so you can maximize your braking ability. I don't know, just an idea

I think that'd be an awesome idea, and it probably wouldn't be all that hard actually. All you'd have to do is extend the brake lines. The only issue could be mounting it somewhere since it'd have to be in a fixed position if you use hard lines. Maybe you could get away with a few inches of rubber brake lines though...who knows. Nevertheless, a cool idea, and that's more or less what I'd want to do. How much do these adjustable PV's cost? I'd check, but I gotta leave to go to work right now

6/11/04. marking this day on the calender...eric had an awesome idea involving cars.

I know wilwood has an adjustable PV, and there is a tech article written on it. Not sure of the price, but it can't be to outrageous.

Both Wilwood and Stainless Steel Brakes Corp. (SSBC) make adjustable prop. valves.

Price is around $49 for either one at Summit. SSBC also offers a choice of finishes - black anodized or polished - AND the SSBC versions are available with a pressure gauge attached for around $30 extra.

ive got one of the wilwood **** style proportioning valves i didnt use when i upgraded to ls1 brakes all around. i decided on one less thing to mess with so i bought a 1le one. $40 shipped and its yours

On my track only drift car (89RS) I'm running the Wilwood 6 way adjustable proportioning valve with the lever adjuster. I mounted it right in my center console so I can adjust the bias while drifting like you are saying. Yes its possible and not that hard. However I have not driven the car on the track yet, so I cannot verify that it works flawlessly (though I cant imagine why it wouldnt). The rest of the braking system will consist of the Spohn Big front kit and matching rear kit Dean found (Dean is the man!) for the 10 bolt rear (byebye 9 bolt and PBR's). As of right now, everything is still boxed (working on some welding). Cant wait to get the rest of the car completed and out on the track so I can try out all this new stuff!!
