I've been looking for brake conversions for the 9" since at relatively fast speeds i want to be a little more confident that my 3,600 lb car will stop. also any upgrades to the front that you can think of would be wonderful.The only conversions i found were like wilwoods Pro street that says "Not for everday street use" or "for offroad use only" which i really don't like to read about brakes!! or should i not bother, and upgrade the drums some other way ------------------

I've used the FRP disc brake kit 2 times and have been very satisfied both times. They work nice on the street and track. The only problem that I had was trying to find banjo bolts for them. I ended up making my own with stainless steel bolts and machining the holes to specs. The P/N is M-2300-G. They even come with a nifty mini drum parking brake that works real nice. I think I paid around 350 bucks. Good luck, if you need more specs let me know and I'll look them up for you.
Later, Gordon

Try the enclosed hyperlink
I had drums up front, and bought their conversion kit, nice stuff!
They have conversion kits for the rear also, and unlike wilwood, these kits are made for street use. spendy stuff however!
I looked at it this way, the bone yards wanted $600 for used greasy slimy parts to convert, I spent a grand and got all new nice parts, instructions, and no hassle.http://www.stainlesssteelbrakes.com/intro.html quote:

Would think your rear axles are the small bearing ones since it came with 351w.

The Wilwood stuff is fine, the only reason they say "Not for everyday street use" is that they have not dumped huge cash getting some kits DOT certified.------------------

Most of your stopping comes from the front brakes. I would put disc brakes on the front, and not worry about the back. Back when I ran my granada, it weighed 3500 lbs w/driver, adn ran 10.80's at 124 mph. It had factory disc brakes on the front and truck drums on the back. It stopped great and didn't have anything exotic, or high priced for parts on it.

I have stock discs on the front at the moment, would like to swap them out for some dual (or quad) piston with larger rotors as wellplus the aluminum reduces unsprung weight which will help the car handle better on road too

Dubz,No more weight than you are going to save switching from stock to aftermarket disc brakes, you won't even notice the difference or a performance enhancement. If you really want to improve handling not necessarily stopping power over what you have now, improve the suspension parts with the money yhou are going to spend on 4 wheel disc brakes.

 So you expecting your car to run 175 mph? Or are you going to enter a slalom race for heavy cars? If you want the car to handle better, try getting rid of about 800 lbs of body weight before worrying about unsprung. With the weight of the car as it sits, you could lose 100 lbs of unsprung, and not notice a darn thing on the street, and only gain a tenth, maybe a little more (and I mean only like 1 or 2 hundredths), on the track.

Memories, oh the memories.
I remember when we would spend all of our money to make our cars faster... but could care less about the braking system... ha! quote:

rear seats are gone, i'm having a aluminum fuel cell built for me, aftermarket adjustable shocks are in the works, control arms as well, and poly bushings all around
I realize that there will be hardly any difference in the weight of the brakes since i am going bigger, but the single piston are steel or iron which would be heavier than the dual piston aluminum stopping power is a big deal in a big car (to me anyway) the car is going to be for the street and cruising as well as the track so the brakes need to be up for the challenges of everyday driving (avoiding accidents and such) [This message has been edited by Dubz (edited 09-17-2003).]
