UNLOCK THE TRUE POTENTIAL OF YOUR TRACK CAR

Most people think of an LSD upgrade as just putting more power to the ground. Yes, that is ONE of the things it does. What they don't talk about is the increase in braking performance, or the removal of understeer, or simply how it impacts turn-in and corner exits... It changes everything, and for that reason, it's a make or break mod, because we put the time, money and effort into the swap and if it's not spec'd appropriately, you might have just made your car worse. 

If you have a diff builder locally, or are a diff builder yourself... you can purchase the LSD unit and install parts. If, however, you'd like a fully built and assembled pumpkin, you'll need to send your diff, or a spare, and we'll handle the full install and refresh of necessary components. This is the recommended approach to guarantee a flawless install. 

We promise this is one mod you won't regret. 

OPTIONS:

This is for a Drexler 6+6 Preloaded diff with 65/50 ramps, optional 50/40 (more aggressive). If you have a custom specification or special Drexler part number you'd like, we're happy to accommodate -- please reach out.

We can also go with a shorter final drive ratio, like the BMW Motorsport 4.10 that we run in our E92 6MT. For DCT cars, you'll want a 3.62 FD.  Yes, this will increase RPM's at cruising speed but we'll be damned if the NA S65 wasn't meant for these gears. It just comes alive in every, single, gear. This is the way. 

Please note, due to availability of Final Drive upgrades from BMW Motorsport and otherwise, lead times can range from 1-6 weeks depending. 

Due to variation in packaging, weights & locations, you will be charged for shipping separately after purchase.
