eLSD question

HoldMyBeer · 07-19-2019, 04:27 PM

Hi guys, I searched and I couldn’t find a previous thread for my question.

Today, I was practicing quick/fast launches and noticed that I was getting 25-27% slip on eLSD display and never have seen it anywhere near this high before accelerating in straight line. I was going straight as an arrow and was not spinning my tires. It occurred with launch control off and no nannies on. Also with track mode on with sport1, 2 or track launch control enabled which really threw me. I saw it from 0-60 mph and from 5, 10 and 20 mph to 60 as well.

I know there may be some slip going around corners but haven’t seen this during straight line acceleration.

Any help appreciated if anyone else sees similar during straight line acceleration.

I believe thats the difference between the rear and front slippage. Any chance your rear tires were lower pressures or you changed your front to rear tire OD stagger?

Tire pressures were all good. Stock rims and Goodyear’s with good tread as well.

Perhaps a slight difference in the surface of the street, or the tire's temps were not equal. Pretty cool!

You ought to try your suspension in tour...the car sits back better on the rear tires....this advice really worked for me!

top number is the percentage of lock up rear wheel to wheel.

Bottom number will sweep red is the slip.
