#1 its not a real LSD, so who knows how it would work other than in a straight line

#2 the thing works by installing over the spider shaft in the differential. When you hit the gas, the spider shaft wedges into the two blocks of the PG, pushing them apart. These in turn press into the output gears, creating a LSD effect. There is no way in hell I would want the spider shaft in my diff constantly wearing against hardened steel plates. You would end up wearing right through it and causing a catastrophic diff failure.

Quoting Super Street as a source is the first problem. Second, for hardly any more money you can get an MRS LSD. Install is probably cheaper on the MRS part since it doesn't require disassembling the diff. Basically, there are no upsides to the Phantom Grip in my eyes.

I believe a MRS LSD can be had for around $600, less if you find a used one. Lets say two hours labor to install the Phantom Grip on top of a standard diff install, so an extra $160. Now you're talking $140 difference. Is that amount of money really worth it? A helical diff is a proven, reliable and trusted method for limited slip on a FWD car. Super Street are total ricers known more for photos than anything. They were probably paid by Phantom Grip to print what they did. Readers of that mag would be the kind of people trying to cut corners on everything. Again, there just are no upsides to this as far as I'm concerned.
