On my '85 RX7 GSLSE I found that I need new strut supports on top, (see alignment thread). I decided to replace the Rotors as well and ordered the drilled and slotted ones from Mazdatrix, (Brakenetics 45012). They seem a bargain at less than $90 ea. They came with new studs. I'm having a shop do the work and am concerned that these are not like the stock threaded ones. Is it hard to install the studs? Will my shop have problems? Why the difference? I'd appreciate some prompt advice on whether its an issue.

 

They'll be OK. There pressed in.

 

Thanks.
