I finally made it to the inspections yesterday (4 months too late, but better then never

). I passed emission testing (AU) with distinction, 0.01% CO, 0.3% max is allowed

- the new heated 02s (thanks Bruce!), the MSD ignition and the accel coils simply work great.
But i didn´t pass the main inspection (HU).
Not because of my mods, that cool TUV guy even liked them, but because of my rear brakes (fronts are still very good) and the worn out front lower ball joints. The rear calipers don´t build up much pressure anymore and work very unevenly (80:130), so does the emergency brake (30:85). I think both rear calipers are shot (worn guide pins, worn out emergency brake cable springs etc etc...).
Is there a way to upgrade the rear calipers?
(LS1s? Wilwood? Baer? Something < $400....)
I could simply rebuild them, but I think i want better ones.
I have the same rear end as the LT1s (3.42, LSD, discs),
so everything that fits there should fit my car, too.
When my front calipers go bad, I will upgrade them, too.
And what ball joints should i get? (brand? greaseable or service-free?)
Thanks for your help!
