I am looking into get some ITR calipers but they come with t23 caliper brackets, will they work on 89 CRX DX knuckles or do I have to have the T25 brackets?

 

Well then can anyone tell me where to buy some?

 

they will not work on DX calipers, if you want ITR calipers you need to get some 90-9 EX spindles and have them machined down a little to make the ITR brackets attach to them. this is the only way I know of to make them work on an EF.
