So, I'm tearing down my rear end in prep for welding the tubes, welding the relo brackets, etc. I came across these brackets -

They back up the rear caliper mounting tabs.

Why are they there? Any reason not to delete them? If I need to keep them I'll probably weld them to the tube while I'm welding and delete the muffler clamp looking portion, just to clean it up down there, but they seem superfluous to me, and any weight pulled off of the rear end is a good thing.

Any wisdom? Thanks.

Well, it bolts to the brake caliper so I'm guessing it has something to do with the ABS. I would absolutely leave it as is unless you're stripping the car down to make a race car.

I am. That said, I'm keeping ABS.

But it doesn't interface with the wheel speed pickup at all. Only with the caliper and the axle tube.

I believe it is the extra support for the rear calipers especially under heavy braking it will make a difference.

I believe it is an anti-moan bracket. It keeps the rear calipers from making noise. They had them on sn95 mustangs and they didnct affect braking performance if you removed them.

That's what I was thinking. I remember seeing something somewhere about them being for noise control or chatter or something like that.

They are called "Anti Moan Brackets" With them bolting to the specific Caliper Bracket Bolts and then wrapping around the Axle tube they help absorb some noise in the brake system.

I took mine off since they seemed like dead weight to me. I haven't had any issues yet, but all i do is light driving/cruising and drag racing.....if I was autocrossing or road racing, maybe the extra bracing would be important?

Well, I suppose I'll leave them off but not throw them away. If their use becomes justified, I can add them back. One thing working in my favor is the fact that they will be stopping a much lighter car. Put it on the scales last week and it looks like 2900# as a first pass will be pretty doable, and 2700# with some work is reasonable.

WTF, did you forget to put the motor and trans back in?

As a roller with a few parts I will be using missing, but a few others that I won't be still to be removed, it was 2200#. The complete drivetrain on the shipping pallet was 700#. So that's the roughly 2900#.

2700# is going to mean gutted doors, lexan windows, and probably losing a fair bit of weight in the bodywork. I'd rather keep it weather tight as long as possible though.

At the power to weight ratio you have it is time to consider some race brakes. Aerospace makes some pretty nice stuff at reasonable prices!

If / when I time trial it, perhaps. As a solo car, pimpy brakes seem superfluous.

Dave is this your CP build? :p I'm excited to see what you come up with.

For the record, my 09 Premium with lighting package, heated and power leather seats and Shaker 500 came in at 3441 lbs with coilovers, Fays2 Watts link, Strano 35mm front bar, stock 20mm rear bar, stock wheels and 245/45/18 Dunlop Star Spec tires. The only weight removed was the spare and it had an 1/8th of a tank of gas.

I ran my car this past weekend with the car screaming 25 miles to empty at the end of my last run and didn't have any fuel starve issues so keep that in mind Dave! :)

I've identified about 155 lbs of weight to remove between exhaust, seats, wheels/tires, brakes and battery. That would put me at about 3286 lbs at race weight!

Speaking of CP, are you going to run a locker like you mentioned over on the Sandbox? :p
