Locking the rear diff will make this worse. What car do you have, and what setup are you running?

When I say setup, I mean suspension settings. You can try more rear toe in, softer rear springs, and I could make a list that goes on and on.. One big thing, if you are still using the kit tires, ditch those and get a set of good ones, and then see how it is

It'll make it worse. Try softening your rear suspension a bit, try some traction compound on the rear only, change your EPA so your front wheels don't turn as sharp, add some rear camber and toe-in.... but don't lock your diff.

If you lock up the rear gear diff, you are actually making the car a drifter.

Because of the setup limitation of tt01, you may try softer spring / lighter damper oil, more rear toe in and better rear tires for sure.

You may also want to soften your throttle when exiting a corner to avoid spinout/drifts.

Try softening your rear springs a bunch first, and adding some rear camber. Rear toe in isn't possible with a TT01, I don't think. Also make sure your front tires don't have better grip than the rears. If anything put the better tires on the back.

Simple definition of toe in: When a pair of wheels is set so that their leading edges are pointed slightly towards each other, the wheel pair is said to have toe-in.

In short, more rear toe in helps keep the rear of the car planted, and that will help the problem you have, although im not sure how easy it is to adjust on a tt01

Adjustable arms only allow changes to camber, not toe in/out.
