Rear Disk Swap
Wednesday, February 07, 2007 3:15 PM
I've been researching a few set-ups now and I was going to go the neon-swap route, but the rotors are a little smaller than what I really wanted.

I'm just asking to see if anyone has done any swaps with something closer to an 11inch disk as opposed to the neon-swap or a box setup (Wilwood, SSBC, etc.)

Thanks.

plenty have done ssbc and baer. one guy did a wilwood but needed a larger master cylinder to power it all.



My car may run 18s, but I can do your taxes in 10 seconds flat.
JBO lube - they would never have enough in stock and we'd never see RodimusPrime again

I'm looking to find those who haven't used an "out of the box" system. I know a few have done the IRS swap, that's more than what I am looking at.

Mainly, I'm looking for unique set-ups and how you went about doing them. I'm leaning right now to working with a Lebaron rotor and utilizing a Cadillac caliper (uses my stock e-brake without modification). Anyone done one similar?

there is a neon-ish type of swap that has 11" vented rotors. its in the swap thread.

That would be me.

Cliff...

I pieced together my own set up with Joe's (Racetech) help. Give me a call or msm me and I'll tell you all about it.

Hey Aaron:

I talked to Joe about your set-up, it's awesome. Just need that new master cyl. eh? LOL

I'm not going that extreme and the worst part is that Joe lost the parts list for the swap him and Frank designed. So right now, I'm flying blind without anywhere to look to find anything about using his brackets. Sucks so much right now.

I'll have to chat it up with ya soon, maybe we can come up with something.

Viper - thanks, i'll have to dig through all those pages and see if I can find it.

I am currently working on a cobalt/G6 rear disc set up on j-cars. 10 1/2" disc, 12mm thick. I think it is better because :
1. it is a thicker rotor,
2. it does not have a seperate e-brake, -less parts
3. it's all gm.
i will offering it as a g/p once i have it all working- waiting for my brackets from the machine shop

Please be sure and let us know how this turns out. The G6 setup uses a vented rotor right?

That would be a good swap to have. Keeps everything in line and looks almost identical to the fronts.

Keep me posted.

the G6/ cobalt rotor is not vented, but you can get drilled and slotted if you want. .. p.s. i am working on 12 vette rotors on the front too!(with the 5x100 pattern)

^That is already possible....NFW + Corvette calipers........just do the swap with dual stud pattern hubs with studs in the 5x100 location and a redrilled rotor to match.

Bingo... I would leave the nwf swap alone and not try to re-engineer it as its a perfect fit and swap.

So far with the corvette stuff i'm playing with, caliper uses a machined bracket bolted to a modified upright. no changing axles or hubs. just a hubcentric ring and a re-drilled pattern. less than $200 projected cost!!



Re: Rear Disk Swap

Yes but by keeping the stock stuff your getting only the brakes as a upgrade. There are a couple advantages such as less unsprung weight aka aluminum hubs, bigger wheel bearings (as all j owners know stock j wheel bearings are crap) bigger brakes and its not all custom stuff, only "custom" part is the axle which are easy to come by. no modifying is really needed on the swap except axles which are easy to do anyways. otherwise its a bolton affair.

also with increased braking forces it would be wise to have better/bigger wheel bearings.

Very true, but this going to be the wife's daily driver- (03 LS Sport, 18" BSA 304's, Razzi body and Magnaflow cat back)
I have a W body 13" wilwood setup for my 3800 s/c project lined up for this spring/summer

Dont forget the aluminum GA control arms that you can put on while do the swap....just adding big calipers really ruins the possiblities you can have on the front end.
Re: Rear Disk Swap

Is the GA control arms a direct swap? Is there a thread where I can look.?

It can be both, it can be a direct swap if you have the supporting mods (chamber plate) since its ~0.5" longer but if you have plates you can just slide the strut out and make up for the width. The other way is to shorten the CAs, either way its not that big of a deal. There aluminum so its not hard to weld closed the original holes and redrill a little further back. There is a big thread on this but its not a sticky so it fell off the first page, but its not far down.

my drums just broke on me and i hate the ugly f****** anyway. do i have to make my own bracket for the neon swap or do some guys make them to sell. i think im going with the srt4 setup because the bigger brake can anyone guide me in the right direction?
