90Q Rear Brake Options

[klkinc123]

Hi All;
I was wondering if anybody could recommend a good performance Rear Brake 
Upgrade(Setup)
for a 88 90Q? It has solid rotors as of now and I have heard of a vented 
rotor upgrade.
I am not looking for a big dollar upgrade(ie RS2) just the best bang for the 
buck. I am in need of doing a complete rear brake overhaul, so I am checking 
my options.
Thanks in advance!
Cheers from Boston
