I'm looking into an LSD for the E39, the DSC isn't overly great when wanting to drive in an enthusiastic mannor and with it off, 1 wheel breaks traction all too easy

Now, I know that an LSD unit can be retrofitted from an m3 (non evo version) into the E39 diff with the E39 CWP

But, what do the numbers mean - 25%, 40%, 60% lockup - its all double dutch to me

Shamelessly copied Paul!

"
The percentage number denotes the percentage of torque applied to the
slower turning wheel from
the faster turning wheel. In a straight line, both drive wheels turn at the
same speed, so no limited slip action is occurring. In a turn, or when one
tire is spinning more than the other (such as on snow or ice), with a
limited slip differential, 25, 40, or 75 percent of the torque applied to
the faster wheel is applied to the slower wheel,
effectively 'limiting slip'. A higher lockup percentage will cause
increased rear tire wear on the inside tire during cornering -- the tire
itself will have to slip slightly to counteract the limited slip's desire
to have both tires turning at the same speed. It will also increase
oversteer in wet or slippery conditions, but it will also increase
understeer in tight corners under dry conditions. This is simply due to the
fact that with a limited slip, the drive wheels tend to want to turn at the
same speed, making the car tend to want to go in a straight line. When it
is slippery, however, both drive tires will tend to lose traction at the
same time, increasing oversteer. "

 

Thats just the ticket Mike - Cheers (shameless copy accepted )
