5 of 5 14 q50 3.7 lsd kit June 21, 2022
Reviewer: Sherman from Olympia, WA United States  
I'm loving the confidence I'm feeling from launching and fast and tight turns. Previously I was thinking my tires were the main issue. I have Firestone Firehawk AS. After installing, I have yet to brake traction with the same tires. Unless I wanted to.

Before - Launches were terrible from the 1 wheel peel. Couldn't do a donut or get the car sideways. -(Fun stuff). When I would do a fast tight turn the car would correct itself and quickly straighten out. Super scary honestly.

After, all of these issues were resolved. Although I haven't putt it to the test, I have not broken traction with traction control on during daily spirited driving where as to before it was a daily occurrence to where I would lose traction due to the open diff. Now it's is very predictable and I need to find out how hard I can push it before it wants to lose traction.

Honestly, I couldn't be happier. NOW the car handles like it's supposed to. Feels like it's on rails. Can't give enough praise.

5 of 5 LSD! February 25, 2022
Reviewer: Ramsey from CA  
The TC LSD kit is a MUST for any Q50 owners (yes even AWD ones). It's a shame Infiniti left an open diff from factory when these cars can produce a lot of torque and power with little work. I bought a 2021 Q50 RS (RWD) and ended up buying this kit within 3 months of ownership. The OEM open diff kills the fun especially if you're trying to put the power down.  I did my homework regarding the install of this kit and if you are some what mechanically inclined it's a fairly simple and straight forward install. Gina from Traction Concepts was amazing and always there to help if needed. The kit has cut down my wheel spin by a ton, made it much more enjoyable to go through corners and exit aggressively,  and overall made the car more enjoyable. This is a must have for Q50s if you really want to enjoy it. Highly recommended!!

5 of 5 Q50 RS 17 January 8, 2021
Reviewer: Uzair Shah from Phillip, ACT Australia  
Installed the LSD Kit of Traction Concept on my Q50RS RHD. Works a treat ! My car is tuned with LDP, complete exhaust and produces 500bhp and 575nm torque. With only RWD it was really hard to get of the line (even with light weight alloys wheels and rear 265 tyres Michelin Pilot Sports) i always use to correct it and you can feel the chassis is taking the pressure as axle is loosing traction. After installing the lsd now it is a big improvement in start of the line but the main difference is on cornering. You can turn and immediately accelerate and the lsd will take care of everything. It is a must have if you have tuned your car and wants to not worry about loosing the traction.
