I sold them and bought PBM (I wanted the alternate geometry of the GKTech's, but I wasn't happy with the quality and they wouldn't fit my front brake kit of the time or the voodoo arms I had at the time). This was all on my road race S14.
The rear PBMs were tight on the Z32 e-brake stuff, but I was able to get everything installed without too much hassle. The rest bolted just fine to the SPL rear arms I now run as well as the voodoo arms I had when I first bought them. Hard to say the difference they made because literally the entire car's suspension changed at the same time.
The front PBM knuckles I literally just bought for my S13 because it'll be more setup for drifting than road racing, but I haven't bolted them to anything yet. Only thing I can say is that they look nice, but are 1.9 lbs heavier than stock knuckles (each), which is kind of a bummer. It makes sense per the design, but I think they could have improved the casting a bit. I'll still rock them for awhile though, as this car is more of a budget build.
I'd be interested in seeing what the geometry of the geomaster knuckles are as well as the fit & finish quality. Especially the rear, as I need another rear set of knuckles. I'd move the PBMs to my drift car and put them on the grip car.

I actually have a full set of geomaster 2s. Finish is concerning. Their new (at the time) coating didnt seem to be very effective. There are spots of rust and inside the sheet metal design of the knuckle seems to have more blemishes that i cant reach.
As for fitment, they seemed to have fit without much problem, altho i didnt use a drum brake in the rear.
The brake caliper brackets looked like they werent aligned, but after test fitting everything, there doesnr seem to be weird braking issues YET. I havent really tested the car yet aside from driving it in teaffic back and forth from the alignment shop. We put the set on my drift car, but these were supposed to go on my all-out-dream spec 180sx street car. I think id rather go for a more modern set of knuckles with better quality for my 180sx build. Im just trying to figure out which brand caters more towards my goals.
-stock drum brake no problem
-maximum roll center correction
-steering geometry suited for aggressive drifting at the track, but also be able to put down great lap times
Compromised, but able to do anything fun i want to do.
The new GKtechs state that for s13 era rear subframes, their rear knuckle adds quite a bit more anti squat and it would be best to pair the knuckle with their s13 anti squat reduction kit (modify the rear subframe). The new DW collab with wisefab (Geomaster 3) doesnt state anything about anti squat tho. Id like to use a set that is perfect for the s13 rear end out of the box if possible.
