car weighs about 3150rw.
on drag radials and skinnies do i need a proportioning valve? I still have completely stock brakes.pictures would be nice if you have deleted your abs and have no valve how does it drive.

my previous car had a 9" so there was no abs but everything else in the braking compartment was stock and it drove fine

 

Why wouldn't you want a prop valve?

Without a prop valve you risk locking up the back brakes first upon a hard stop. It would not be safe for you or the person in the lane next to you....... please get one.

thank you sir.
has anyone wrecked by not having a valve?il probly get one,but i dont think its that big ol deal,better safe than sorry

 

I don't have one on my car and I have had no problems, all 4 tires will pretty much lock up together if I STOMP on the brakes, but honestly, I don't ever see a need to do that. Even at the local track with a shorter shutdown I never had a problem from 142+ stopping the 3400 lb car.

Now it will be about 2900 when I'm done and going over 150, but the weight out of it I think it will stop no problem, and I will have a chute to pull as well.

 

We don't use a valve in our ABS delete or manual master kits.

 

I should make note, that I have a Burkhart master cyl on my car, hence why I didn't need the proportioning valve.
