New Product - Swift Spec-R Sport Springs for your E82 135i

Swift made Sport Springs Spec-R is made for true track racing enthusiasts that wants to take their vehicle to the next level.
Sport Springs Spec-R is engineered with 2 main characteristics.

1 Redesign lowering ride height to maximize the suspension performance allowing the vehicle to fully absorb road condition for maximum traction.

2 Increase in spring rate to further enhance cornering speed through entry & exit. The increase in spring rate is based on the vehicle factory stock valving settings. Sport Springs Spec-R is increase to the optimal rate that the stock shocks can handle. Higher performance shocks are not required, but recommended.

Spec R springs are wound with the same engineering as our sports springs. With the exception of stiffer rates and slight change in ride height; you can expect the same characteristics as our sports springs.



H5S.TW

Motorsport's most advanced spring material


Swift made a name for itself on the tracks of Asia, Europe, and U.S. by defying all accepted concepts and speculations about the future, if any, in coil spring science.
When many other company were looking at expensive and brittle titanium composites to create the next evolution of springs, Swift was looking at reinventing the entire science of coil spring dynamics. Swift saw that most others are using the old regular silicone chrome material, which was not strong enough. It used a heat tempering method that damaged the strength of the material that requiring more coils, in turn, more weight.
The material was also suffering from a short life span. With springs like this leading the industries, Swift saw room for improvement.

Swift's R & D team created material, called H5S.TW, which is stronger then regular silicone chrome material. Because of this material, we could make the spring wire thinner, and could wind the springs with fewer coils, which greatly decreased weight while dramatically increasing available stroke.

135i lowering:

1" in the front and 1" in the rear (from non-sport).

Spring rate:

-3.6kg/mm or 201 lb/in in the front
-9kg/mm or 503 lb/in the rear

Hi Harold.

Seriously thinking about pairing the Swift R spec springs with Koni Sports (inc adjustable rear shock option). Would they fit my Ground Control "Street" Camber plates or do I need new ones?

I track my 2011 135i M sport often from April to October, and use it as a week-end driver. Roads are not in very good shape here in Quebec, Canada with our nasty winters. With my bad back, Im hoping this combination wont make the ride too harsh, especially if I can quickly/easily dial the front+rear dampers from "firmer" to "softer" position.

How wide can my tires be with these springs, struts, and shocks?

Thanks.

Thanks Harold. Posted back here so others can benefit from your expertise.

My street setup is stock style 261 rims (18x7.5" and 18x8.5", with 225/40 and 255/35 RE-11 rubber). No spacers + no rubbing, with or without GC camber plates.

For wheel/tire fitment and clearance, am I also good with LTW5 17x8.5 and 245/40R17 racing compound tires?
