I would greatly appreciate anyone with an axle lying around right now to measure the offset of a 3rd gen 10-bolt (wheel side of axle flange to wheel side of axle housing flange). I am too tired to pull things down and measure right now and really won't have time until next weekend. I quickly got under the car assembled and it appears to be 2.50", but not certain without pulling the rotor off.

Reason why I ask is- I am interested in wilwoods 140-7148d rear brake kit for the 4th gens. It specifies an offset of 2.75". (thats the only questionable factor, everything else appears to line up).
Thanks for any help,
Dean

Edit: That kit is a 12.19" rotor/ 4 piston caliper with internal parking brake setup for $694.00 through Summit.

That kit is a bolt on for your rear, the only things you need to fab are the brake lines to the calipers and the parking cables.

I just got done installing the LS1 rear brakes on my kids Camaro yesterday and think it's a better setup for a street car. The LS1 brakes have a drum parking setup and the rotors are 1 inch thick. The cost is way less and factory repair parts are at any parts store.

Also the LS1 front will be the biggest front to fit in 16" third gen wheels and I have that allmost ready for install on the front.

Thanks to Dynodon and Kevin91z for the great job on the rear brakes. I drove in Dons shop at 8:10 am and drove out at 11:50 am with the new brakes and a Zexel posi and a gear change (2.73 to 3.23) and we also did a speedo drive gear change. Later that day we did the swap on Kevins car in less than 2 1/2 hours.

Thanks Jerry for the info.

However, I am looking positively to get away from a floating rear caliper. The rear rotors on the car now are 1" thick (10.5 dia) but calipers are crappy floating design. I personally want to go with a lighter/but better quailty, and larger dia rotor to offset any heat changes of the smaller thickness. The main and only reason I am change out the rear discs I currently have is because of the POS pain in the ***, tempermental,,,, floating caliper design. When combined with a c-clip axle runout, these floating calipers are just a continuing problem under hard cornering. The lag time in release give a continual residual rattle and moan.

I am also going to the 13" Wilwood kit in the fronts and fell this will give a nice balance in both performance and looks. I like things to match (Like a washing machine and dryer, cant stand different manufactures on things that coordinate- make things look mickeymoused). The only thing I don't like is it doesn't offer a 2pc hat option, so I am limited to any rotor selection. I don't see any wilwood upgrade kit for the LS1 rears other than the kit I mentioned above.

I'm lost- this sucks. I really badly want to go to 2 pcs rotors since I have to upgrade the binders- but I want a parking brake on this car because it will remain a street car and the wife drives it alot.

I just venting my thoughts out loud- Maybe Wilwood or Baer will here my thoughts and package a kit to fit my desires. I don't want to run floating calipers like Baer offers with there two pc design. And wilwood does not offer an iron hat that will fit my application for a 2pc internal parking brake design.

What to do, what to do??? Maybe I'll scrap this rearend for a quickchange rear axle setup (NO, its just a friggin street car)

Edit: I conversed with Alloy (Dan) and he advised me that Wilwood's "Spot Calipers" are not adequate for an E-brake function. Only to hold the car still when parked. ANd a pinion e-brake is out of the question because of interference with the TQ arm.

I submitted an E-mail to Wilwood on the availability or custom order option of an iron two pc rotor hat for the above kit #. I'll post any response if/when I get it.

Great news- Wilwood e-mailed me back and it appears they already have the same 4 piston caliper kit above with 2pc hat and rotors instead of 1pc. The part # is 140-6744D and is for the '93-'01 Camaro and has the internal parking brake.

Summit sells it for $718.99 http://store.summitracing.com/defaul...44-d&x=16&y=13

Compared to Baers rear kit with only single piston calipers and 2pc rotors for $1055.

Less expensive and better performance. Its a perfect compliment to Spohns 13" big front brake kit

I had posted a picture of this kit earlier and didn't relise it was the entire kit w/ brackets and parking brake assembly. Those are two pc rotors that mount to the back of the hat (looked like one pc in the picture because no rotor-to-hat bolts show.)

Out of curiosity any chance that kit can be made to work on a 9-bolt rear? Or is there a different kit that will work? I'll soon have my 1LE front brakes on the car (finally) and need to start thinking about the rear brakes.

More than likely I'll go with the correct 1LE rears or an LS1 rear set-up to have PBR calipers at all 4 corners and keep the cost of replacement parts down. Still, it doesn't hurt to explore other options.

Bret, Off the top of my head, I can't remmeber what the 9-bolt flange looks like. I don't, from what I recall, think it will work- but I am not certain about that answer.

JERRYWHO

A 9 bolt has a differant bolt pattern than a 10 bolt, So its not a bolt on. The backing plate might have the room to move the bolt holes but thats a shot in the dark.
