KMP BMW F Serie Final Drive i=4.11 Ring and Pinion

KMP BMW F Serie Final Drive i=4.11 Ring and Pinion
Buy Now: $1,953.57

The BMW F 220 Rear axle has a welded crown wheel on the differential casing. If you upgrade to a BMW 220 Limited slip differential, you need to machine the original differential in order to use the original crown wheel. If you use this shorter final drive, you don’t have to machine the original OEM differential. The ratio change to 4.10 or 4.11 is very common for track usage.

KMP has produced a stronger, but also lighter final drive for the BMW 220 differential with a ratio of 4.11.

The BMW 220 rear axle is used in the models F87 M2, F80 M3, F83 M4 and more. This crown wheel pinion can only be used in combination with the steel carbon shaft, not with the carbon version. Always check which model type is needed.

FAQs & Notes:
OE Gearing: E30 M3 is factory equipped in the US spec modes with 4.10 gears.

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 but going to 'tight' with your gear ratios may cause you to be shifting more often than is ideal and may reduce highway comfort on street cars.

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 or rally racing.

OE vs. 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 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.
