New E46 M3 Street Camber / Caster Plates from Turner Motorsport

**TurnerMS** · 11-04-2004, 12:32 PM

Pricing will be updated early next week on this product. The TMS stock style caster-camber plate is designed with a custom urethane bushing to be used either with the stock or PSS9 front strut/spring assembly. Installation is to simply replace the stock strut bearing with our assembly (reuses stock spring perches and bearings). Every dimension of our camber plate kit is based on the stock strut bearing to ensure a perfect fit. Camber has a wide range of adjustment, from stock to a full race setting. These plates are the result of several months of design and testing. Detailed settings and combinations will depend on each car’s suspension geometry. These plates are also easily interchangeable with our E46M3 Race camber plates. This is a great option if you ever desire to go further to a more solid race suspension, as they utilize some of the same parts. There is NO other camber plate like this on the market.

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

Manufacturing 
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.
<o:p>
</o:p>

<o:p>
</o:p>
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.</td>

Design 
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<st1:PersonName w:st="on">
sue</st1:PersonName>
s. The main goals for this
product are: 

<ul>
<li>
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. </li>
<li>
Maintain proper
strut angle at any position by not pre-setting the angle.</li>
<li>
Provide proper
orientation with a replaceable urethane bushing </li>
<li>
 Minimize
any noise associated with the urethane bushing</li>
</ul>
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.
<o:p>
</o:p>
 
 
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.
