This brake upgrade is getting more expensive by the mod.l bought my calipers at the Pomona swap,cheap and loaded with new Ferodo`s,l couldn`t lose,the seller stated they were from a 944 turbo. So after welding,machining ,blasting and now red powdercoating l need to purchase and install the rebuild kits.Our host doesn`t have any,Performance same thing.Mid America has them but there`s two different options and they`re not cheap either,$40.00- $70.00 per caliper! Can anyone help identify which kit l need? One kit applies to 928s/s4 86-88,944t 86-89,944s2 87-89,944ts 88 and the other option fits 944t/s2 89-91,968 92-95 that`s the front kits,rears are the same designations.l don`t really want to order all of them and send back what l don`t need....also is that a good price? l know there`s some brake guru`s out there,any help appreciated,as always
