I don't know what rear pads I have, whatever came with the calipers from Advance. I wonder if there's any extra clamping to be picked up with wagner pads?

 

I know i can stand on a long bar i had attached to lugs with wife only pushing pedal down half way

Before with the twin setup i could turn the rear by my hand with pedal pushed all way to floor

 

You might want to try the SUV rear brakes first. They are a dual piston caliper and direct swap. Just get the rears for an 05 Tahoe. That's what I have on mine and they are very stout.

George is right the 2 step makes launching much more consistent.

 

Suv arent a direct swap with the the 1320 brackets
Also will need alot of grinding and not sure how banjo is so may not clear bogarts

 

No but they are a direct swap to the backing plate that normally comes on the 10b. I think they work fine with 16" wheels, really doubt 15s without grinding.

What size wheels are you using?

 

Correct as my crewcab has them

But then you gain weight going back to stock stuff

 

If you gain at least 0.1 in the 60ft by being able to brake boost harder, is that worth the 10lb or so for the bigger calipers? I would think so. What does 1 suv caliper weigh compared to 2 of the ones on the dual caliper setup?

 

A front rotor is where ya drop weight
The billet caliper bracket drops weight
Dual caliper setup of 1320 is a failure

He needs a 2step and hell be fine

 

Atomic, I'm sure you're aware the suv rears don't have a chance in hell of clearing my 15" wheels.

 

Actually no, never messed with them and 15" wheels and I didn't know that's the size you were running (hence why I asked). Nevermind me then, continue on.
