MOPAR Adjustable Brake Proportioning Valve Thoughts?

[Achilles99]

I just picked a GTS, and am looking to upgrade the brakes ASAP. I hated the way my fronts locked up on my RT10, and although EBC's helped modulation, I didn't like the initial bite.

I plan on using Tom's rear caliper mod (bigger piston), and am thinking about installing a MOPAR prop valve while I'm at it. I've heard this is a simple bolt-in piece, that doesn't require any crimping of existing brake lines. It goes inline with the single tube that feeds the rear brakes, and is installed under the hood. Has anyone done it? Where's the best place to buy it from? How well did it work?

Thanks!

Achilles,

Here's what I did. Kept the stock front calipers and replaced the pads with Porterfield R4 pads. Added Wilwood calipers for the rears and kept the stock rear calipers for parking brakes. Installed a Wilwood proportion valve to adjust the bias to the rear brakes. Much better modulation and no more front wheel lockup. Had the work done by Ted May at Valaya Racing 408-448-8811. Give him a call.

Awesome... I'm going to try to find a Wilwood (which I think is the same as the Mopar) that is a bolt-on part for the viper. My Viper tech said there should be one that is pretty much plug and play...
