Camber Plates (Street) for 1999-2006 BMW M3 [E46] by TMS


Quick Overview

TMS Camber Plate for E46 M3 (Street)

Applications: 2001 - 2005 M3 (E46)

General Information
Race camber plates (with solid spherical bearings) are great for the track, but what if you want to drive your car on the street too? That’s what the TMS E46M3 street style caster/camber plates are: A plate you can use on the street, still have the available adjustment of a race camber plate, and not have to put up with a harsh ride or replace the bearings every season.

The E46M3 STOCK strut mount only allows about ½ ° camber adjustment and no caster adjustment. For most track cars or street cars that occasionally see the track, that is not nearly enough. The stock strut mount is also set at an angle that is suited only for that position, and puts additional bending load on the strut if it is not in its original position. The TMS Caster/Camber Plates allow significant camber adjustment from approximately -1.2° to -3.85° and allows for the needed strut angle change.

***Note: Each car’s suspension setup/geometry/ride height will be the limiting factor on range of movement.

Our Plates directly replace the stock strut mount, and incorporate a replaceable custom designed urethane bushing. The stock spring perch and bearing are retained in the assembly, allowing this part to be used with stock or aftermarket struts, such as a Bilstein PSS9 kit. Basically, this is a must for any one who will be auto-crossing, going to track days, or doing any performance driving, and still needs their car as a daily driver.

Each part of the TMS caster/camber plates is CNC machined from aircraft grade aluminum billet. All aluminum pieces were then coated to MIL-A-8625F Type III spec hardcoat anodizing. Each steel part was either powdercoated or nickel plated to QQ-N-290A Grade F specifications. High grade hardware is used and main internal threads are helicoiled to add strength and life.

The urethane bushing has been custom designed and manufactured specifically for this part and its required characteristics. It is now undergoing lifetime cycle fatigue testing. Real world testing was done using the TMS Red M3, and they are still being used.

This product has been fully engineered and designed by Turner Motorsport R&D in–house. The assembly is designed to directly replace the stock upper strut mount. Each piece has gone through stress analysis, and all movements were pre-simulated in CAD to eliminate any potential interference is sue s. The main goals for this product are:

Large range of adjustment while still allowing caster and camber to be adjusted from the top without cutting the strut tower. Cutting of strut towers significantly reduce their strength.

Maintain proper strut angle at any position by not pre-setting the angle.

Provide proper orientation with a replaceable urethane bushing

Minimize any noise associated with the urethane bushing

The surrounding casing and bushing (internal and external) have been designed to work together to allow the proper strut angle to be maintained during adjustment, reducing the bending force on the strut itself, while offering longer life, and proper dampening. This was done through Finite Element Analysis to predict flow characteristics in different situations.

A scale for camber and caster has been laser engraved on the upper plate which will always be visible for adjustment, and the upper plate is a full round circle to better distribute the force on the strut tower so it is not compromised. This has shown to be a problem on several BMW chassis’, including the E46. This TMS part will not accelerate strut tower deformation.
