The Quaife ATB Helical LSD (Limited Slip Differential) is a popular aftermarket differential option for the Birkin S3 Roadster.The LSD is designed to improve traction and handling by distributing torque evenly between the two drive wheels, reducing wheel spin and maximizing grip. This is especially beneficial in high-performance vehicles like the Birkin S3 Roadster, where power delivery to the wheels is crucial for optimal performance.
The Quaife ATB LSD uses a helical gear design, which provides smooth and progressive torque transfer without the need for any clutches or plates. This design ensures that the LSD operates seamlessly and does not interfere with the normal operation of the vehicle during low-speed maneuvers or cornering.
Installing a Quaife ATB LSD in a Birkin S3 Roadster can significantly enhance the car's performance, especially in situations where traction is limited, such as during aggressive acceleration or when cornering at high speeds. The LSD helps to reduce understeer and oversteer, allowing the driver to maintain better control and stability.
Overall, the Quaife ATB Helical LSD is a popular choice among Birkin S3 Roadster owners looking to improve their vehicle's traction and handling characteristics.

Grill Fits…
Fits my 650i perfectly. Easy to install, took about 30 min. Inexpensive way to modify from stock chrome grill to black grill.

Excellent fit and finish for the money. Just buy them.
Size: For BMW E46 2002-2005, Size: For BMW E46 2002-2005
Perfect fit. These grilles were better quality than the price would suggest. Easy to install, not brittle, and fit very snug. I’m not sure why there are so many negative reviews for these. I was fairly rough with the first one I installed and it didn’t crack. They look great. For a purist with excess money lying around, sure, go with genuine BMW. For a daily driver, you’d never know the difference aside from the black finish. Save the money spent on these over the OEM BMW and use it for something else.
Below need not be read unless you like long winded car resurrection stories...
The back story on the car for those who might wanna talk trash about its condition:
I bought this ‘01 330xi from a buddy who really beat the car up. I’ve had to replace the entire front end and am in the process of painting the car. I had to source a hood at my local pick ‘n pull due to low funds because I bought a new house recently. The hood I found at the parts yard was for an ‘04 e46 (post facelift). Hood fits just fine and the grilles are perfect. Don’t hesitate to buy!
