Installing a limited slip differential.

maverick1 · Jun 13, 2026

I find that when I accelerate hard in my Fiesta ST I get noticeable torque steer, and not the best traction.
Will installing a limited slip differential address both of these issues, the torque steer and the limited traction?

Yes it will drastically help. When you go over stock turbo levels it'll come back tho

I'll keep that in mind.
Thanks.

A LSD will not change the unequal lengths of the CV axles that creates torque steer in the first place.

A LSD will increase cornering traction by preventing all of the engines power to unload on the inside wheel. 2 tires are better than a 1 tire fire.

If you want a cost effective improvement, I found a traction bar helped a fair bit with torque steer. Better tires helped too.

One of the best mods I ever had done was to install a LSD! Night and day!

Thanks gentlemen for your input.
I bought my Fiesta ST used and when I went under the car to do it my first oil change I noticed the previous owner had installed an aftermarket rear motor mount and blow off valve.
That motor mount definitely helps with wheel hop.
