Being that I'm always looking to something completely different (and most of the time just plain expensive) I'm thinking of re-engineering the rear brakes on the E30.
Since I want to install a bigger rear brake to balance out the fronts that I'm putting on (11.75" 4 piston kit), I started thinking of ways to reduce the unsprung weight on the rear.
While I can do it by making a rotor with the park brake drum as part of the hat, the aluminum hats and calipers will reduce the weight by 6-8 lbs per side compared to the stock components, but I then thought, why not eliminate the unsprung weight altogether?
How you ask? By moving the rotor/caliper assembly to the end of the differential output/axle flanges, like the old Jaguar XKE. This would allow the use of just the drum portion of the existing rear rotor, by machining off the friction surface of the existing rotor.
Then I could design a carrier to mount the caliper off the differential and have the rotor on the axle flange/axle.
Of course this is in the 'what if?' stage, but it sure seems like a trick way of solving the problem, so I'll just have to get out the extra diff and see what I can do with it...
and please no posts on 'why change the brakes, they're good enough', they are NOT good enough for me :)
