33 Differentials

Date: 17/10/24

Hi Kevin,
It was nice to meet you yesterday.

I just wanted to let you know the the new Quaife Differential has made a huge difference. I haven't heard any noise at low speed manoeuvres, but it has also vastly improved traction. I think the previous MO LSD was well past its best. It would often snap the back end when losing traction and would also push the car sideways. Even when wet and loosing traction the car now remains straight when accelerating 
It was defiantly a good decision.

Many Thanks
Mark

Hey james I just got the diff fitted today and man is this thing phenomenal. It literally puts drifting on easy mode I feel like I unlocked a new feature on the car. It's insane! LSD>Tune ! Thanks alot for everything you made the experience as smooth as the LSD's transitions :D

Hi James,

Yesterday I put the differential on the car. Everything went smooth,no problem encountered.

My car has completely changed! It is a whole different car. Traction drastically increased in freezing temperatures. Sliding feels natural to the car now and the car is fully controllable.

I'm happy I took the route to add the missing piece the car was needing. Thank you again for all the support! Ive had a ~40 mail thread with you.

Wish you all the best!
