im looking to but front calipers for my 90 ws6 formula, my question is: is this the (performance version) of the brakes-even though i have drums in the rear?or are they considered being the 'normal' calipers?seems that (ws6) would mean calipers in the front AND rear!!!!!??? i do not have "1LE". thanks-brad

 

From what I know not all of the WS6, IROC, and Z28's came with rear disks. It was an option that had to be selected. I still dont know if this is true. But alot of people told me that all front brakes are the same. Weither RS, IROC, WS6, etc. The only different front brakes are from the 1LE. So I'm guessing these calipers might just be the ones you got now just new. O_o
