[QUOTE=AllShowNoGo;7303172]Have you ever installed a phantom grip on your car? Or are you just going by what you hear on the internet? Ive got a car with an OEM lsd and my phantom grip grabs just as hard as that. I think the people that have problems didnt install it properly. CFT ran a phantom grip in their 9 second hatch, Skunk2 runs a phantom grip in their 9 second RSX.

+1 havent had a problem yet, have always run them without issue
the, ys1 LS or Gsr diff has the same casting number as the hydro, have swapped several ys1-hydro diffs and their all the same except for the carrier bearings, tapered vs ballbearing, so i dont see why it wouldnt fit, and actually on that obx diff. i've seen more of those fail than anything else, the bolts that hold em together seem to backout and or snap, and well BOOM!
