Coleman has been around for decades and their prices are excellent considering they are making a pair of new custom rotor rings from scratch. Best part is you don’t have to buy 10 sets!
Girodisc has a 380x35mm and 355x35mm disc.

Stoptech and supply chain issues are becoming like peanut butter and jelly. You can get rotor rings - just need to look around. Turner is out of stock on the 355x32 discs but Amazon.com has them in stock. Most of the parts are standard stuff except for the caliper brackets. The rear rotor hats might be hard to find. McMaster Carr has all of the hardware. Just got some damned $10 jet nuts - $80 for 8 nuts!

You can work around the supply chain issues for the most part, just not convenient.

I do miss their racing brake pads. The SR34 pads felt like PF01s but wore like PF08s...the best brake pad I've ever used!
