Im in the process of upgrading to LS1 front brakes. Im just curious how much of an improvement there will be. Also, what brackets do you guys recommend for the swap? Thanks

 

They definitely "feel" better. The pedal will be softer, though. But theoretical max performance should be more than your tires can handle with both brakes. I think from a physics and thermodynamics point of view, the main advantage of bigger brakes is better heat dissipation. So factory brakes will get too hot and boil the fluid ,but LS1 brakes will take a lot longer to do that for several reasons.

 

got ya, thanks

 

I didn't change driving style,
I found that I got 3x as long on a set of pads. As stated above better heat dispersion.

 

The heat dissipation notwithstanding, the larger diameter rotor will certainly aid in the stopping power. Simply a result of greater leaverage. I can't say I encountered a "softer pedal" although I can understand where that might come from. I made the move from a rear factory disc equipped IROC to the LS front brake conversion and PBR rear calipers and rotors. Kept the same master cylinder and prop valve. I also purchased the upgraded prop valve from FlynBye but I've yet to install it. I can't say I've experienced any braking unbalance but then again I haven't open road coursed this car. Just a street car/cross country cruiser and about a million quarter mile blasts.
I used the brackets supplied by Flynbye performance.

There's a wonderful brake upgrade comparison chart that lists pedal effort as one of the data points. Most will decrease pedal effort with the factory master cylinder.

The real world is often more complicated than numbers, but it fit my experience.


The increased leverage of larger rotors may also help heat dissipation since less pad pressure is required for the same amount of stopping power. I dont know for sure that it works out that way in practice, but still. Also, you probably will get more life out of pads with larger rotors for that same reason. There are a lot of benefits, including stopping power, but stopping power is tough to take advantage of. Admittedly, the amount of grip a tire can hold depends on a lot of factors and dynamic weight loads and so on, so it's not as if it makes no difference on street tires, but to really see a stopping power benefit you need good rubber.

 

skinny Z where did you get your rotors?

 

Local parts store. Of the shelf for a 2000 Camaro. Same with calipers.
