FS: UUC EVO3 Short Shift Kit (E46 M3)

Selling a slightly used (7mths, 2300km) UUC EVO3 Short Shift Kit with DSSR (Dual Shear Selector Rod) for an E46 M3 (non SMG). Bought it from Turner. Paid around $400 shipped. Will not sell DSSR separately.

Turner Part# USSE6M3

$300.00 FIRM
Local pickup only, no shipping.

Description:

New EVO 3 edition! UUC's latest update has resulted in even smoother shifts, a reduction in vibration, and more features! UUC redesigned all of the pivot points in the shift linkage to reduce notchiness. The result is a shifter that is 35% shorter than stock but feels closer to the stock effort. And new internal dampening material doesn't transmit vibration to the shift knob. Simply-put, this is the most complete short shift kit on the market. All UUC Short Shifters are height-adjustable over a 3/4" range - giving you the same ergonomic comfort as the original. UUC's Short Shift Kits include: T-304 stainless steel shift lever, sealed lower pivot bearings, and new installation hardware. Delrin shifter carrier bushings INCLUDED for the E46 M3. This is the best Short Shifter money can buy!

Want the ultimate shifter feel, with the least amount of lateral play? Upgrade this kit by adding a UUC Dual Shear Selector Rod ("DSSR" for short). A DSSR can be added to any shifter setup (stock or aftermarket, including this UUC EVO3), and when combined with the EVO3, you will have the most accurate, most precise, and simply the best shift setup available for your BMW.

DSSR in Detail:

UUC Double Shear Selector Rod for E46 M3 Increases the precision and smoothness.

The Goal
While producing a "short" shifter, our more important goal in improving the BMW shifter assembly is to increase the precision and smoothness of the overall operation.

The Problem
One significant wear area that has never been addressed previously is the wear and ovalization of the linkage connection points at the transmission and the shifter's lower pivot.

In the original BMW design, the connection at both ends has a large injection-molded plastic bushing. We already know how badly plastic wears in an automotive application, and these areas are not an exception. The design of the selector rod has a pin at 90 to the main rod, which exerts a tremendous amount of leveraged force on the selector joint bushing from one side (known as a single shear force). The result is a steady deformation of the bushing, resulting in looseness and slop in the entire mechanism. (see photo at right) The image shows a selector joint that has approximately 25K miles of use. The looseness and slop are magnified by the leverage-multiplication effect of the shift lever itself. The result is an in-gear shifter "free play" of 3/4" and up to 1" in either direction, over 35mm total.

The Cure
A temporary fix is to simply replace the selector joint. Unfortunately, this is only a temporary fix as the new joint's bushing will exhibit the same rapid deformation. To permanently fix this, a change in the fundamental design of the pivot is required, changing the assembly to a double shear system with the UUC Double Shear Selector Rod (DSSR).

The DSSR redistributes the torsional forces from the pin/bushing interface to the complete face area on both sides of the selector joint. By taking advantage of the strength of steel in the DSSR and the body of the joint, the problem of deformation is eliminated and the movement of the selector rod correlates directly to movement of the selector joint - the only "free play" movement remaining in the shifter assembly is from within the transmission itself. In-gear "free play" is reduced to approximately 10mm total when used with a UUC EVO3 shifter.

The original BMW shifter and all other aftermarket shifters (except UUC which uses deformation-free bearings) contain a plastic bushing similar to the selector joint, and the exact same wear and ovalization causes those shifters to get sloppy. The DSSR permanently fixes these shifters also. The DSSR is compatible with all brand shifters, whether original BMW or other-brand aftermarket. When used with the original BMW shifter or other aftermarket shifters, the amount of "free play" will be greatly reduced but varies by shifter (flexation of the shifter shaft contributes to the total "free play" travel).
