New Product - Swift Spec-R Sport Springs for your E9x M3

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.

M3 lowering:

1" in the front .75" in the rear.

Spring rate:

-5kg/mm in the front
-12kg/mm in the rear

so those are roughly 280 in/lb front and 670 in/lb rear? Are they linear and how do they fit in the stock location?

Yes, they are linear rate and fit in the stock location to replace the OE springs.

Wow thats an awesome setup. Perfect spring rates for pefromance on the stock shocks. Too bad I already ordered my KW CS.

Great to see Swift Springs releasing a setup for the E9X M3.

In your experience and opinion, how do you think the ride will compare to the Eibach Pro-Kit and H&R Springs. It is often said that the Eibach's are just as street compliant as stock, where has the H&R variations are bit choppier.

These do seem to the lower the car ever so slightly more than the Eibach. Would this effect comfort?

The ride is firmer than stock but still comfortable, it's not choppy at all.

What is the difference between these springs and springs that are part of the TC Kline spring conversion kit for EDC?

These are sport springs, similar to Eibach and H&R, NOT coilover type spring for an adjustable height/sleeve-over kit.

No, they are not. During extensive testing by Swift there were no issues.However, there is nothing wrong by adding them if they provide additional compression travel.

How do these compare to the RD Sport springs? the drop seems to be about the same.

Are you going to increase the suspension travel with the milled mounts and bump stops?

I'm eager to hear your review. It'll definitely save me a few bucks from going Dinan.
