Wilwood DynaPro Low-Profile Rear Brakes I recently just installed a set of these brakes and was very happy with the quality of the kit. I wanted a kit that would work with my 15" rims and maintain a parking brake. The directions from Wilwood were good so no need to go over them but I wanted to add a few more pics and comments from my install.
First a little background on my rear set up. I have a Moser 12 bolt that is narrowed 3" per side and use a Weld 15"x10" with 5-1/2" backspace that tucks the tires nicely.
Second learn from my mistake. I used the Wilwood site to select my kit and when you go to the page with the axle flange selection there is an option for 12 Bolt-Late 93-02 Camaro. This is not what you want to select if you have an aftermarket rear. The kits here will work with a stock rear end only. What you want to select is towards the bottom of the chart called a Chevy (special) axle flange end if you have a 3.150" press on bearing. The kit I choose is 140-11401.
Axle with bearing pressed on
Chevy special flange end
Axle installed (note bearing hang out from flange)
Backing plate with parking brake
Retaining plate
Before retaining plate installed
Retaining plate installed
Axle with backing plate installed
Low profile rotor
Caliper
Mounting bracket (needed to add some shims to make sure I had enough room between rotor and bracket. Verify this upon assembly. This kit is for a 2.81" offset and mine was close to 2.75")
Rear side of tire showing clearance of brake set. There is more than enough clearance with my rim set

I have not gotten to test them out yet. I am converting my car back to more street friendly at the moment. I had a set of Aerospace drag brakes before and the Wilood's are a little more heavier due to the wider rotor. But the shipping weight was 45#

I have a similar setup to you, and was about to order this kit and you just saved me a ton of hassle as I was about to order the wrong kit as you did. Thanks a million!
I have a question for you: were you able to retain the stock parking brake cable? The gentleman at Wilwood told me I would need to replace the cable.

I will be using a new one from Wilwood when I install since I removed all of the stock stuff when I tore the car down. I'm not sure if the stock one would work but there is only one way to find that out!

Ha! Good point. Thanks again for the help. I'll report back with whether the stock cables work for future reference of others.
Mind if I also ask what you did for a brake hose? I was also told by Wilwood that my OEM replacement hoses wouldn't work, but it seems the Wilwood ones only come in very long sizes.

The calipers have a NPT threads hole in them, you can get a NPT to AN nipple to put on the calipers then use a short AN braided flex line, and get a adopter fitting to got to AN off the stock rear brake line of the rear end. Or make new brake lines on the rear end and put a NPT to flair fitting on the calipers for the line style.
These brakes are great for a street setup. I ran the dynalite setup with the parking brake and was 3K race weight
on thing is the rotor hat is raw and will rust. I painted them.
I went to strange drag brakes on my car and I'm selling them willwoods right now actually great deal if your looking for a better the stock, lighterm and clears 15 rim setup.

I ran the stock parking brake cables. The willwood bracket is thicker, I'd gues its 1/4, were the stock in thinner, its thick sheet matal. The stock cable fits the willwood bracket, but the end has fingers that clip after the slot to hold the cable in. But the thicker braket slot is to thick. For them to fit past to clip and hold onto. So I just put a small hose clamp (3/8-1/2) on the backside of the cable end, and just snugged it up. It was fine and kept the stock cables tight in the slot for falling out.

Thanks for the help, JR. You saved me a ton of trouble with posting up the correct part number. I placed my order this morning for the brakes.
studderin- Thanks, but as said, I already placed my order. I'll try your trick with the hard lines and parking brake cable end. The price Wilwood is charging for the lines and cables is pretty outrageous!

there is some pics in the build thread of the brake lines. I used some of the stock flex lines for the ABS on the front, it worked out great and was free
I cant find one of the cables, but its just a hose clamp on the cable end inside the arm bracket.
One thing I would do beofre you put these on your alxes, in to cut a slot in the backing plate so they fit around the axle, like most other brakes. When there soild you have pull the axle bearing off to get the backing plates off. I always messed them up, and had to buy new ones. Its a paint in the *** to cut and pres them on and off, and cost about $50-60.

and having the star flange is alot easier to install these new. you have room to put the drum shoes on the springs
If you have axles with a full flange you can't get the normal drum brake tools on the springs so you have to use needle nose pliers sideways and it s bitch. I found it best to build the parking (drum) brake shoes and the springs, and adjust them for the rotor hat to work before you have the backing plate installed behind the axle flange. I always left the drum brake assembled on the backing plate, Its tight but the shoes are on the springs so you can flex them away for the backing plate a little and get a gear wrench behind the shoes. 11mm on the axle flange nuts, and do little 1/20 turns back and forth with the nut. That way u dont have to take the shoes off to get room, to them form the front. Look at the pic at 10 and 2ock. the 4 axle hardware you need to BEHIND the drum brake parts is a bitch. your understand when you use these on the full axle flange.

Thanks. Yes, I have a full axle flange so I imagine it will be a pain as you say. I thought Wilwood shipped the backing plate assembled with the drum assembly ready to go? Why would tools be needed for anything other than adjustment once its on the axle?

studderin thanks for the heads up on the stock parking brake cable I will see if I can re use mine when I get that far. One this is you do not need to cut the backing plate with this kit. the backing plate fits over the press on bearing and is held on by a retaining plate so you can take them on/off as much as you need to without pulling the bearings like with other kits.
