i have this in the brake forum with no responses. it is lt1 specific so it should be able to go in here.

I am looking to upgrade my 94 formys brakes to ls1 style. Do i have to get brakes from a ls1 or will a 99 v6 work? junkyard has one and I am contemplating getting the brakes. are the ls1 rear brakes better at all?

 

Any 98 up F-body (V6/V8) has the Big Brakes, and they work very well. I would leave the Rears factory, that way you can put on 15" Drag Rims..

 

I don't know the answer to fitment, but I would only do the fronts. They handle 85% of the stopping, and would be the most cost-effective solution.

 

what all do I need for the swap. anyone have pics of whats needed?

calipers, rotors, lines???,spindle....anything else

whats a good price for all he parts and how big are the rotors compared to the lt1's

 

You could replace your LT1 front calipers and spindles for LS1 units (that's what must be done) or simply upgreade to ceramic pads all around - much less difficult, with the same results.

My $0.02...

 

It's not the same result. The LS1 rotors are larger, by an inch I think, so of course they're going to stop better

 

Check out these guys, they have some outstanding prices and kits:

And also they are dual piston calipers, so just replacing pads can not give you the same result. The most basic aftermarket brake kits for the LT1 cars come with dual piston calipers, must be better than single piston calipers.

 

I have a set of ls1 calipers / rotors for sale if you need them (no spindles tho). pm me for details.

 

Man those are some really good prices.

 

Yea they are! $100 more for dual piston Vette kit O_O

If you ever need to do rotors and pistons it's almost better to just buy one of those kits. If you have to do spindles, then it's a no brainer!

 

is 250 a good price for the entire upgrade from a junkyard. I can get the rotors for 25 each the calipers for 25 each and the spindles for 75 each. is that a good deal

 

I got it all for $150 when I did it...

 

For $200 I was able to get complete front and rear set up. Yes the rear does make a differance. The best part of the LS1 rears is the E-Brake will hold the car along with them being a little lighter. The LS1 fronts are a LOT lighter being a Alumn. caliper with almost 3"sq of swept braking surface. Found it to be much better the ANY LT1 combo I have used.

 

can anyone tell me what part the spindle is. I am gonna run to the junk yard probably tomorrow. does anyone have a pic of the spindle

 

The Spindle is the big chunk of steel that holds everything. The Hub is what is connected to it and that holds the Rim and Rotor on. I am sure you can figure out the rest.
