I am looking to get this 85 SPG, but I'm concerned with the fact that it's got solid front rotors. The rotors are new, so they won't need replacing for at least a little while, but I'd much rather have vented ones up front. Given that I have an 87 SPG with new front rotors at my house, what would it take to swap in the newer brakes? Also, how involved is it to switch everything over to 88+ style. (Iknow you need the whole rear axle and front hubs). Another problem with 85's is the wiring, but that was recently replaced as well, so I'm not worried. My last question for now is the APC. Iknow the 85 has the APC under the rear seat, and in a different case than later years, but is it hard to get aftermarket units for this year? Or is the inside the same? Thanks a lot. Oh, and basically everything in the engine compartment is the same as say, an 87, no? Also, is there such thing as some sort of airflow package for the 85 and 86 SPG. I thought I'd haerd something, but maybe not. Sorry for all the questions, but Thanks!!
