Brakes for an S52 Swap...

What about just going ATE calipers with solid bushings?

Do ATE calipers offer better clearance?

What would bushings have to do with brake clearance?

I'm not clear on how you can be having clearance issues on stock brakes, and then solve that with Wilwoods.

The clearance issue isn't because the caliper is too wide and hits spokes like most, it's because the caliper carrier is very large down near the hub face. Moreso than a lot of cars for some reason. I have a set of Rota Grid wheels and a set of Rotiform wheels that the entire hub area was beefier (I presume to account for the many bolt patterns available) and interfered with my stock calipers. Both were supposed to fit. I grabbed a Wilwood setup from Massive and gained a bunch of space because the caliper body is similarly sized but it's moved up and out radially.

I assume the rear is an ATE, you could check out the design differences

Solid pins firm up the brake pedal but require more maintenance
