I'm installing new brake lines and wanted size and fitting suggestions. Also whether or not to use proportioning valves. I was thinking of 1/4" stainless hard line front and rear to "T's" and then flexable -4's to the calipers. Or maybe I should go with smaller 3/16" lines up front? What is the best set up for brakes on a Big rear tire/ skinny front tire car?

Mark, What you do is right on target for what I'm planning. Being a twin turbo car I will be doing other hard lines as well. I like your mounting hardware for a round tube chassis. What is the best time to call you?

tt --- Bent's stuff is better than killer huh!!

WOW is the best you can say about that!!

Okay -- He'll tell ya - I think - that when using DISC brakes - use 3/16" lines...

Personally and this is arguable - I'd go without a prop valve - but it depends on your car and your set up. Basically the valve is there to reduce pressure to the rear tires -- but you said you're going to do big rear tires and little fronts -- so the fronts are going to lock up before the rears anyway... so why add a pressure reducing valve that wouldn't "be used".... Just MHO... You just don't want the REARS to lock up BEFORE the fronts.... if they do - then you need a prop valve for the rears...

Okay - let the flaming begin!! I'm sure I'll hear about this opinion... :>)

Actually, my thoughts are the same when it comes to the propotioning valve. Running 33" tall x 18.50 wide rear sticky tires, there is little chance you will lock them up before you lock up the skinnies up front. My last car had narrower tires than this (31 x 14.5) and no valve. I never locked up those tires either and that car had a hydrobooster as well.

FWIW, I talked to a buddy of mine last night who has a similiar setup and he said he used to have a valve and took it off. He said it worked better without it.
