By standard calipers I would imagine standard TA22 ones? Are the TA22 discs vented to start?
I have XT130 struts and standard calipers, discs on mine, and it pulls up very well. Non-vented disc though, but I've never overheated them (with my slowbie 4K).
Any idea if the Cressida discs will fit over the XT130 axle stubs? What about the calipers? Will they bolt onto XT130 struts? I roughly measured the mounting bolts on one of them (I was in a hurry) and it appeared to be 90mm as well...
Or I could go with the Pug & Hilux conversion... But I've just gotten new brake pads and rebuilt my calipers so I don't see that happening anytime soon...
