Why a suregrip?

BTW
1) the CONE-type Mopar LSD, the one that has two large spiders, can be adjusted from full-open action to almost spool type action, by some combination of cone-preload, oil type, and amount of friction-modifier.
2) the other type of Mopar LSD, the one that has clutches and four smaller spiders, can also be adjusted, but it's torque-sensing system has a broader smoother range.
At low torque-input it acts like an open diff. At max torque input, it acts like a spool. By varying the torque-input, you can vary the holding force.
For my driving style, this has a special meaning.
I like to drift as often as possible.I have set my car up to make this a relatively safe operation. When I put the power into it, she locks up and a-drifting we will go. If I feel that the drift is not going all that well, I just lift until the clutches relax, and the tires grab, then hit it again. While the tires are catching, the car may do a little lurch, which, when it happens, scares the crap out of passengers, so I don't take passengers with me anymore.
But I gotta tell you, this only works with tires that have lots of width, cuz the brakes don't work when the car is going sideways, and I depend on the now-floating contact patch to accomplish braking Before I installed 295s, not spinning-out was always a challenge. With the 295s, first and second gear drifting are almost too simple; turn steering-wheel, apply gas-pedal until tires spin, control speed and direction with gas-pedal, applying occasional counter-steer as may be necessary. Note-to-self, try to have the front tires pointing in the direction of travel when relaxing the gas-pedal, for minimum lurch.
