BMW Camber / Caster Kits for BMW 3 Series E93 (2007-2013)

One of the tricks for getting your BMW to handle better is to add negative camber to the front wheels. This will put more of the tire's width in contact with the ground during cornering. With more rubber there is more grip. BMWs typically have less camber in the front to create understeer. But if you're running a stock setup on the track or autocross you are giving up speed and time as the front tires run out of grip sooner than they should.

Our E90 E92 E93 fixed camber plates are designed from the knowledge we gained from our highly successful racing campaigns with the E46 in the Speed World Challenge series. Our camber plates are offset for the best camber and caster combination for racing purposes when using the stock-diameter sized springs. Camber increases to -2.5° depending on your individual suspension setup, while only increasing ride height by 6mm. The rate of camber change is virtually unaffected throughout the range of suspension travel, reducing the need for other geometry correction. Fixed mount camber plates are legal in many racing and autocross classes - these are the perfect camber solution when adjustable plates are not allowed in your class.

These are very simple to install, requiring only pressing out locator dowels and studs in your factory strut mounts. See below for detailed instructions.

The camber plates improve on the amount of adjustment and fine-tuning available in the front suspension to improve mechanical grip while cornering. Made to the same quality you'd expect from Dinan and BMW, they help to fine-tune the right amount of camber for Dinan springs.

• Improved mechanical grip
• Reduced understeer
• Works great with Dinan springs

Upgrade your E9X BMW with this all-in-one Turner Motorsport bundle featuring Fixed Camber Plates and Monoball Front Thrust Arms. Designed to improve handling, reduce deflection, and increase steering precision, this package delivers a noticeable performance boost both on the street and track—all without breaking the bank.

E9X Front Camber Plates – Fixed Position

Most BMWs leave the factory with conservative front camber to encourage understeer, which compromises handling and accelerates tire wear by reducing contact patch engagement. Turner Motorsport’s Fixed Camber Plates are a simple, effective solution, adding up to 2.5° of negative camber to your E90, E92, or E93.

By increasing front negative camber, you’ll enjoy:

Improved turn-in and cornering confidence

Reduced tire wear

Better overall handling balance

Designed with expertise gained from Turner Motorsport’s participation in the Speed World Challenge series, these plates are offset for the optimal camber/caster combination when running stock-diameter springs. They add only ~6mm of ride height and utilize the factory upper strut mount for a clean, straightforward installation—perfect for racing classes where adjustable camber plates are restricted, or for enthusiasts who want a simple, cost-effective negative camber upgrade.

Installation: Press out OEM studs and alignment pin; see Turner’s detailed PDF for guidance.

Monoball Front Thrust Arm Upgrade Kit

BMW’s stock front thrust arm bushings are soft, compliant, and prone to wear—allowing fore/aft wheel movement that degrades steering feel, alignment, braking response, and tire performance. While designed for comfort, these OEM components fall short for enthusiasts and track-focused drivers seeking maximum control.

Turner Motorsport’s Monoball Front Thrust Arms solve these issues with:

Sealed OEM BMW ball joints for exceptional durability

CNC-machined 6061-T6 anodized aluminum bearing assembly with knurled OD for perfect press-fit and long life

Low-friction, no-bind design to eliminate unwanted suspension deflection

The result? Instantaneous turn-in, precise steering, direct braking feedback, and exceptional suspension feel, all while maintaining comfort and reliability for daily driving. Perfect for track use or spirited street driving, these thrust arms are a no-compromise upgrade for anyone looking to enhance BMW front-end performance.
