I know some are using aluminum fittings with their wilwoods, however in the instructions for the front brakes it says

"The caliper inlet fitting is a 1/8-27 NPT. The preferred method is to use steel adapter fittings at the caliper, either straight, 45 or 90 degree"

any one having issues with aluminum? did you use tape or paste on the npt side?

I can order steels from summit, but it will take another 5 days :|

as always a big thanks.
