I seem to have a problem with my new brake parts-



Why do I have two different size calipers? Shouldn't I have a front caliper and a rear drum? And why does the front caliper look so much bigger than whats on my car now? Could it be from another car? I hope it all works when it gets together!

I smell a rear disc brake swap I was planning on using shadow rear discs, I've been doing some research and it looks almost bolt on there is just one part that has to be slightly modified, but I'm pretty sure it will work.
Good luck with the swap, be sure to post lots of pics when your done

rear discs and bigger front discs.

Neon rear swap.... Now what larger disks are you going to be using? Those look like 92+ calipers.

Larger front discs... and maybe moving the engine about 6" back for even better weight distribution.

Thats a 93 Bonneville caliper (same parts as the STS swap, its common to quite a few cars, including F bodies), but I'm going to be using the factory J bearing and machining the spindle to maintain the 5x100 pattern.

I wish I could move the engine back. After I get the new suspension in (coil-overs in front and adjustable perches out back. Konis all around), I'll cornerweight it for a little bit more of an edge.

machining... is in griding with an angle grinder like the wilwood install? Or actually using a fancy cutting / metal working machine.

CNC lathe and three axis milling. Fancy stuff.

Yeah its nice having access to all that isnt it
I've been looking for bigger front brakes for a while now, How big are the bonneville brakes? And what the rear brakes from?

Check this for the Bonneville/STS info- http://www.v6z24.com/jbodyforum/viewtopic.php?t=59085&highlight=sts

The rear discs are from a 96 Neon. The caliper bracket is the same from 95-02 and the caliper and rotors are the same from 95-04 (including SRT-4), so there are more than a few choices for pads/rotors.

So are you going to be attaching the Jbody hub to the STS knuckle? Or retaining the jbody knuckle and installing the larger calipers?
And what are you plans for rotors??

I'll be using the J bearing on the STS knuckle. All it really needs to work is a sleeve to make up the difference in bearing diameter and three new holes for the bolts.

I'll be using Hawk HPS pads and Brembo rotors all around. Check out my new post for more info.
