Definitely not worth the effort! Even at $100 a side it's a lot of work for the money and time and mess, and little guarantee it'll even fit when done. I've had at least 6 different sets of bogarts on my truck over the years, and every single set has fit slightly differently where every single time I've swapped, I've had to touch up the calipers with the grinder to clear. Bogarts egg shape extremely easily, so even just mounting new tires will bend the rims ever so slightly enough that it'll rub differently.
Although as said above if you grind them to fit racestars it'll clear any bogart, but now you're talking even MORE grinding, and getting into that iffy territory of breaking through into the cylinder area, and although it may clear any bogart, you're in the samecase for any other race star, it may fit it may not.
Lastly, it's more than just the caliper that needs to be ground down. The caliper mounting bracket also needs to be ground down, which unless people are pulling axles to swap pre-ground mounting brackets, in those cases they may as well do the "JDM-Mod" and get the brackets machined to move inwards and not have to grind the calipers anywhere near as far. The brake pads also require grinding to shave the ears way down, or practically off in the case of race stars.
Oh and one last thing, I'd never even entertain the idea of powdercoating. PC is pretty thick compared to paint, so that's even less clearance, and one little scrape and the PC is ruined. I've never even painted my rear calipers up nicely because they still rub here and there, and I just touch them up with a shot of black rattle can.
Every rim is different bud, when owner gets calibers back they might have to grind some.
All these years and you still keep mixing the two up lol
Redrum is talking about brake cali
pers......NOT a cali
