LT1 brakes are fairly weak for our cars, they are a single piston caliper with a relatively narrow and small rotor. If I remember correctly they are aroun 1" thick and about 10.5" in diameter. The LS1 setup is a twin piston caliper with a 1.25" thick rotor that has a diameter of about 12". The twin piston caliper allows for stronger and more even clamping force, and the larger/thicker rotors allow for more heat dissipation. While you may not see a huge difference in braking distance for a single stop, the LS1 setup will give much more consistant results over repeated stops, and will stand up to the repeated braking of a 20 minute roadcourse session MUCH better than the LT1 setup.

As to what's involved in the upgrade, you need the LS1 calipers, pads, rotors and spindles. Most of the kits sold on Ebay include all the hardware that is required.

 

Here's a quote from one of the LS1 brake kits off of eBay...
"These are 12" wide rotors, 1.1" thick, single piston floating aluminum PBR caliper with integral Banksia style system parking drum."

Didn't you say that the rotors were thicker and that they had twin piston calipers? Is this guy on eBay just wrong or what?

 

sounds like the rear caliper...of course because of the parking drum.

On my vette the front calipers are 2 piston and rear are single piston with drum for parking brake.

oh I got ya...anywhere I can get the front brake kit?

 

This is everything you need right here.
They are fun to paint too....

 

What kinda paint and method did you use to paint your calipers? Cuz mine looks dull and flakes off easily. I sanded em down and everything and made sure they were super clean before I sprayed them. I had luck with enamel in the past but didn't last as long so I tried a different route and did worse.

 

Yea Tibby what did you use cause I have a set waiting to be installed and I would like to get them painted.
