I just looked at the DRM line package and the difference with DRM and the others is the DRM is NOT orientated to the rail on the caliper but just uses an adapter to take their lines to the fitting in the caliper. It does NOT use a banjo. I think I'd prefer the banjo but does it make a difference? Don't know.

The DRM fittings tighten to the caliper using a crush gasket like the banjo's, so once they are installed to the caliper, the lines can be removed and reinstalled from the fitting/caliper with no seals needed cause they are flared AN style. The lines can be capped so the resevoir doesn't gravity empty with an AN plug if the calipers have to come off for maint. (but those orange ear plugs worked somtimes with the banjo's)

As you mentioned, they're not orientated like the banjo's. So they do need to be tightened with no twist.

DRM would know for sure if their stainless would fit.

The main reason I went to stainless was cause I was hearing about too many people at the road tracks having the rubber ones blow out of the swag end, probably from heat, so I don't think it's an issue on the street. Probably more about whether you want it to look original or not.

Most of us, daily drivers included have already upgraded the brake lines, oil cooler lines etc because its a smart mod to do. I wish GM had done the same during production like the rest of the stainless lines already in the engine compartment. Reguardless thats what Aftermarket business are all about filling the void.

Nice upgrade. SS is always the WTG. GC

96 GS calipers bolt on, have the same piston dia and use the same pads as OE 90-95 ZR1.

GM told media prior to the 96 going on sale that the GS brake caliper was more robust in the caliper bridge area and, thus, spread less when high loads occured to to heavy braking.

I've never been able to ascertain if that's true, but the GS calipers look stronger and that's why I have a set of them on the front of my 95.
