Frequently Asked Questions & Notes:
Different Gear types?:
-BMW's "standard" 4.10 R&P gears have now become No Longer Available from BMW.
Take note of what your buying: we are offering authentic BMW ///Motorsport gears that are hardened and more finely finished.

Gearing ratios / Why does your BMW benefit from a shorter Gear ratio?:
-Choosing to equip shorter gears means that your effective acceleration is improved by more torque getting to the ground in each gear, this comes with a varying compromise in top speed ability. This is an ideal upgrade for vehicles that see regular track use.

REM Finishing, What Does REM offer my vehicle?:
-REM finishing will offer the lowest level of friction where the Ring and Pinion gears mesh together. This is highly important in situations where the rear differential will see sustained high temps, like road racing.
-Motorsport Gear-sets are already finished from BMW, unlike other types

Gearing capability in E46 M3:
-3.91s top speed is over 175 MPH, cruising RPM @70 MPH is around 3100 RPM
4.10 top speed is aprox 170 MPH, cruising RPM @70 MPH is around 3300 RPM
(Note, this is all depending on tire OD and other factors and is for approximate reference only)

Original Equipment ///M vs. Aftermarket Performance LSDs?
-The Factory BMW LSD is a great diff for stock power levels and standard size and grip tires... However, it falls quite short of an aftermarket LSD; like our VAC unit, or a Carbonetic. When you have big, wide sticky tires and serious power adders- more predictability and performance of an aftermarket unit offer a huge increase in control of the chassis, even for street driven cars. Ask us about upgrading to a performance LSD and be blown away by the difference in acceleration and handling capabilities as well as overall chassis response.

---Important Technicians Install Notes:
Professional installation is crucial for proper ring and pinion operation and life.
Let ONLY a qualified pro install or work on the internals of your differential; technicians & mechanics must be versed in the exact procedure of differential assembly to candidates for your install.
A machinist is the preferable choice for installation.

Not only do we offer various gear sets, but also performance and racing Limited Slip upgrades built just for your BMW and to meet your exact needs. Feel free to inquire and have your Diff built by the pros! Our prices and quality on completed diffs can't be beat.
