Not sure what the wilwood kits run, but I think most people look towards retrofitting a factory hydroboost system before going aftermarket.

I have them, with the Baer Eradispeed rotors And they are unbelievable. You wouldn't think such a simple change would make such a big difference. And for all those to think it's not apples to apples, my existing factory setup was in very good condition and were very respectable for their age. But they have nothing on this set up. I occasionly auto cross this truck and there's not nearly the brake fade I used to have.

Nice to hear that- I've thought about them for the front of my truck for the last few years. With larger tires it is always nice to upgrade the brakes some.

I have the D154 rears as well, but it's really for looks. The POL blackout Wilwood master and prop valve look great too.

Thanks for posting...
Are you comparing to hydro boost or was your truck vacuum boost? Just talking about braking power, not modulation or any of the other performance improvements the Wilwoods bring.

No, I'm still vacuum, albeit with a vac canister due to the cam...thought about hydroboost, but this works so well, I can justify changing it.

And those are direct replacements for the 1.25" rotor setup, right?

Correct. You don't need to change to rotors either. I just wanted them to match the rear.

Awesome. I've always wondered if they were much improvement over stock. It's good to hear from someone that has run them.
