i had rda slotted and greenstuff with standard 242mm brakes on my eg and have done 3 trackdays with them and they are still fine, pads are getting low, but they worked pretty well, after a lot of hard braking it started to sponge up and fade, but i guess it depends what you want the car for...

ive got a 262mm vtir caliper and hub/rotor etc set up again with braided lines to go in too so im in the same boat.. using rda slotteds again (never had a problem so i think youll be fine) and greenstuff again, it works fine from cold and they hold up fairly well

the guy at the brake shop said qfm a1rm are good, similar to redstuff, so need a heat up, but very cheap
a few other guys i know with mirages have used them and said they were shit
and a couple with silvias think they work great...

so very mixed opinions, but the greenstuff is good, and not really harsh for daily driving
