I hope their QC is better than the 4 sets that imploded on my 98 Z M6 within 430 miles. I then went to Richmond. After one night at the track, the r&p howled like a screaming hyena with his ***** on fire.
Little kids were running away.

Motive was a reliable manufacturer back in the day, but they have since moved their mfg operation to Korea and in my experience aren't making good gears.
The last straw for me was a set I bought in 2010, the pinion depth etching included the number "P". That's right, try measuring that with a caliper. Tried assuming it was either a 6 or a 9, set the pinion up accordingly, no dice. The 2.29xx had the pinion physically up against the differential.
The shop then gave up using the etched measurement and did it the hard way, got the depth and preload dialed in, perfect wipe pattern on the gear teeth...and it whines like a tractor when coasting.
US Gear or SLP get my recommendation, not Motive.

"The Dunning-Kruger effect describes a cognitive bias in which people perform poorly on a task, but lack the meta-cognitive capacity to properly evaluate their performance. As a result, such people remain unaware of their incompetence and accordingly fail to take any self-improvement measures that might rid them of their incompetence."
