putting disc brakes on 9" in 76 camaro hobby stock/street stock. The shocks are stock mount so the left rear is behind the housing, and the right rear is in front. what effect does this have on handling? also the calipers are going to have to be mounted left in front of housing, and right behind. what effects does this have on braking and or handling? thanks, neil

The last Camaro I built had this same setup,the car handled great.With the shocks staggered front and rear you won't need a 90/10 shock.

The brake mounting doesn't effect the handeling,however the staggered shock mounting helps to control axle wrap up,especially if you mount them about 3" out from the lower mount.Depending on your ride height,you may need to lower the mounts at the axle.

neil, what type of brake set up are you using? I need to do the same but can't use hat style rotors due to track rules.

Im currently trying to find "stock" rotors with 5 on 4 3/4" bolt pattern that are 11.75 inches in diameter, and have enough offset so that the calipers (big gm) wont scrub the wheels (3" offset, 15x8 racing wheels) our rules say no hats and aftermarket rotors too. I may use jeep cherokee front rotors (4x4) and trim the caliper mounts (flat plate type) so they will alow the calipers to drop down so the pads will come out flush with the rotors. when you use the aftermarket weld on or bolt on caliper mounts you have to have a 11.75 inch rotor, or the pads and caliper will stick up above the rotor and you loose 30% of your brake and also dont have enough rotor surface to support all the force of the brakes. what im really concerned with is what diffirence it makes if any in what way you mount the calipers in relation to the housing. for example, the left rear in back and the right front in the front of the rearend housing. I know that the bleeder has to be at the highest point on top, in order to bleed the air out. also you would have to use two left side calipers with this setup. I want to know how this effects braking and why. thanks as always, neil another thing you need to know is the inside diameter on the rotor and the size of the center hole as well as bolt pattern considerations "BEFORE" you order axles.

Check out www.quickperformance.com go to brakes. They sell a complete kit, but measure the flange on your axles. Not sure about offset clearance with this set up either.

Neil, you want to use early Corvette rotors. They are spaced in far enough to clear and have the 5 on 4 3/4 circle. They are heavy and aren't cheap.
