Experience the Superior Performance of Swift Springs

Not all springs are made equal, and Swift Springs has invested years of expertise and research into perfecting the art of spring manufacturing. The result of their dedication is the innovative "HS5.TW" proprietary steel alloy, which sets a new standard in the world of springs. Swift Springs has successfully achieved several crucial objectives with this material, including:

• Consistently maintaining the spring rate throughout the stroke
• Offering the maximum possible stroke length
• Providing outstanding durability to prevent spring height loss
• Creating exceptionally lightweight springs

Founded in 1997, Swift Springs has built an impressive track record, catering to diverse applications ranging from oval track and dirt racing to the needs of enthusiastic street drivers. With a wealth of experience and a history of collaboration with world-class race teams and drivers, Swift Springs ensures they have the perfect spring to meet any demand.

Maintaining optimal vehicle alignment is crucial, especially when dealing with challenging road or track conditions. To prevent excess tire wear and ensure precise vehicle handling, turn to the Godspeed Project Rear Toe Arms.

These rear toe arms offer stability at high speeds, thanks to their precise alignment capabilities. Unlike traditional rubber bushings that wear quickly, these arms feature solid spherical bushings for exceptional durability. Their heat-treated ball and hard chrome-plated alloy steel composition guarantee strength and longevity.

Not only do these rear toe arms provide cost-effective performance improvements, but they also offer extended adjustment ranges and versatility. Their solid design enhances road feel, giving you more control and confidence in your BMW's performance.

Please note that realignment is recommended after installation, and these rear toe arms are intended for "Track Use Only" due to the increased road noise and vibration caused by solid bushings.

When an E9X is lowered beyond the limits of just lowering springs, the rear wheels toe-in excessively. This excessive rear toe leads to premature wear, that many people attribute to an increase in negative camber. It has become a common belief that an extremely low vehicle will wear the tires wrong as a matter of consequence. It has become standard practice to go as low as you can and proceed to replace your tires every five to ten thousand miles. Whats more is that when the vehicle reaches a certain ride height, the factory arms become maxed out and there is no way to compensate and dial in the proper toe. You're left with an improperly aligned vehicle that is in effect worse off than it was with the stock suspension installed.

This is not only uneconomical but improper and unsafe. ECS Tuning is proud to offer a solution for this problem in the form of Rogue Engineering E9X adjustable rear toe arms. These arms allow for greater toe adjustment on vehicles that have been lowered with a coilover suspension. With the toe set properly the tires can contact the road properly this maximizes grip and minimizes wear. 

Features:

• 100% machined and anodized, 6061-T6 lightweight aluminum arms
• High-strength, 3-piece, rod end (with carbon fiber reinforced, PTFE race) offers longer life for street compared to standard rod ends
• SEALS-IT Rod end seals keep dirt, water, and other contaminants out
• Rod ends feature grease fittings, to allow for rod end serviceability.
• Lighter than stock!  (Stock is 875g, RE arms are 640g)
• Extremely easy installation and adjustment (your alignment shop will LOVE you!)

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
• Worth 1 point toward your Dinan badge

Dinan Performance Springs are matched to your BMW's chassis and suspension components to deliver better handling and looks without sacrificing ride quality. Dinan BMW springs are carefully engineered to work within your car's suspension travel and to improve suspension geometry. Spring rates are slightly stiffer than stock and dialed in to reduce bodyroll. A stiffer suspension makes the car more fun to drive and the lower ride height improves the looks by reducing wheel-fender gap.

Dinan spring specs -

• F: -1/2" (12mm)
  
• R: 0" (0mm)

Fitment note: When used with stock shocks the Dinan Ride Quality Kit is strongly recommended. The Kit consists of shorter and stiffer bump stops and spring perches that work better with the lowered ride height of these springs. While not explicitly required, less than favorable ride quality and handling may result without them.
