I am looking to upgrade my front brakes. The reason being I'm dropping in a 3.4 DOHC and I want to be able to stop better especially sinceI will be Autocrossing. What do you guys recomend? I would like to be as light as possible for the least amount of money and as efficient as possible. I know this would be ideal but I'm realistic so I will probably only get 2 out of 3 of my wants met.

What would be light stock rotors and would it be enough to just put in the S10 Brake Booster with SS Braided Lines and nice EBC pads on ligjt rotors?

What is a light aftermarket option that isn't a ton of money?

Thank you in advance for any help.

XThirtySeven,

What are you looking for with 'upgraded brakes'? Improved fade resistence or less pedal pressure? Your existing calipers are about as light as you are going to find and if you seek improved fade resistence then you really need MORE than stock mass in your rotors to 'sink' the heat and keep temperatures down. That means you need larger rotors which leads to heavier rotors. If you want lower pedal pressure to reach lockup (and get better ability to modulate), then you need larger rotors again.

For your '88, to increase rotor diameter, you will need larger wheels. You can save some weight there over the stock wheel.

My suggestion is to keep the stock calipers and stock master cylinder and buy adapters (available in the Mall) to mount your stock calipers to use with 12 corvette rotors which are drilled to the Fiero 5x100 pattern. This along with SS brake hoses and Thermoquiet or EBC pads should give you improved fade performance, lower pedal pressure to reach lockup, and fairly minimal weight gain.

There are quite a few threads you can find on 12" Corvette brakes covering the details.

The S10 booster and better pads will improve your stopping power. Also, FYI the Fiero Store sells a kit for the '88 Fiero with cross-drilled rotors and Carbomet brake pads (part # 56001). With that kit and an S10 booster, you should be good to go.

Thank you for the advice, it looks like I will be doing the 12" Vette brakes and SS Lines. Not sure if adding the booster would be overkill or not.

Just make sure to check for interference between the nose of the lower a-arm and backside of the rotor. If you don't check this, you will gouge your new rotors on your first trip around the block. Been there, done that, designed a better kit so my customers don't have to worry about it.

I ended up digging a valley into the rotor of my Grand Am brakes because of the dust shield. Looked like it cleared it, but obviously not. Only make that mistake once

I have 88 brakes all around on my 84 (with the 88 cradle) including the MC, booster and prop valve. I also installed 12" vette rotors on the front and the car stops really well. The bigger rotors make a noticeable improvement.
