180sx update:
So I found this magical store called GKTech that sell all kinds of goodies cheap Its a pleasure us stagea owners don't really get, having access to plentiful supply of reasonably priced decent quality parts.
Anyway, ordered their caliper brackets, a upgraded engine fan, and some adjustable rear toe arms to replaced the one that is bent.
I went about replacing the very tired brakes with these new items. The pads that were in it were shot. They were once Bendix ultimates (0-550 degrees), but they had been turned into powder. I'll upload a pic later. So bendix ultimates as a track pad - NO!
I phoned up GSL rallysport and put an order in for A1RM (0-780 degrees)pads all round, and a bottle of TRW GP600 fluid. As usual, great service by these guys, and it was on my doorstep in less than 24hrs.
New billet caliper extenders bolted up, 2 piece rotors on, and pads in, it was time for the Mrs to be called up to do some bleeding. Bled the Clutch too for good measure. Took them for a quick drive to bed in, and the results are amazing. Great pedal feel, and good stopping without having to heave on the pedal to get results. Time will tell if they hold up on the circuit.
Still have to install the toe arms and rad fan, and get it aligned. I'd really like to find out some good suspension alignment specs from some of these track guys and see what I have to get to make it all work.
I may have a lead on an oil cooler, so I will chat about that later, and I'll chuck up some photos for effect tomorrow
