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

HP Autosport · 07-09-2013, 04:08 PM

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) or 0.5" front and 0.5" rear (from sport)

Spring rate:

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

***Available on 7/15***

Are these sort of a "consumer grade" version of Swift's metric springs?

andrey_gta · 07-09-2013, 07:01 PM

These are very interesting, I have been considering them for a month or two.
offer same height as eibach pro, and rates tuned on a 135i with perf shocks/suspension ( i emailed them)

ShocknAwe · 07-09-2013, 08:05 PM

So these were developed for use with the BMWP dampers and NOT the M Sport dampers? Unfortunate if true.

This a lot...

ASPEC135i · 07-09-2013, 09:47 PM

What license plate bracket is that?

I like how its relocated to give max FMIC flow yet doesn't use up the tow hook accessibility

That is what I was told via email from SWIFT, I dont think I misinterpreted the reply.
They said other dampers are compatible too. I think a KONI would be a nice shock to pair with

These Spec R springs were developed around the stock M-sport dampers and is compatible with other after dampers such as Koni Yellow.

andrey_gta · 07-09-2013, 11:08 PM

^^ Thank you. I guess I didn't understand their email reply, didnt mean to confuse people. Their Perf suspention implied m-sport

Bimmer-Bob · 07-09-2013, 11:13 PM

If these are a one-size-fits-all type of lowering spring, like Eibach's or H&R's, I would expect them to be compatible with a pretty wide range of dampers. In any case, I doubt there's enough of a difference between the M-Sport and BMW Performance dampers anyway (at least not enough to make a difference in this context).

John_01 · 07-10-2013, 12:57 AM

Its just my opinion, but I think it would be crazy to keep stock 1 series M-sport dampers with upgraded springs.

I can say from my own experience the Performance dampers are a lot firmer than the stock ones. Still, the adjustability of Koni yellows seems very attractive for these.

How often does the average lowering-spring user feel the desire or NEED to adjust the dampening rate of the strut?

Thanks for the answer! Looking forward to reviews on these.

HP Autosport · 07-10-2013, 11:53 AM

We are looking for a couple of interested parties looking to install these Swift Spec R springs on their 135i. Springs will be at cost plus shipping to you. Please PM and include a few product review threads for reference.

ShocknAwe · 07-10-2013, 12:31 PM

I might be interested, please PM me details!

Zombie1 · 07-10-2013, 01:41 PM

I just got a set of BMWs Performance springs, how much better our these? I may just get them to have a full inch drop on my car instead of the half inch drop from the performance springs. Any info will be helpful, ill test these out and write a review!

If the average user thinks the stock M-sport suspension has sufficient damping from the factory, then it says they are either ignorant or value ride quality in preference to handling. I simply can't see how increasing the spring rates by 66% over M-sport stock is going to allow the M-sport dampers maintain any damping control at all.

I'm in the same boat. Just installed the BMW performance springs with Koni Yellows in the Spring. If there is a significant performance increase over the BMW Performance Springs I would be interested. Although the spring rates look very similar to those of the performance springs. I wish they would have been a bit stiffer.

How's your cars ride height with the springs?, I have them And koni yellows waiting to be installed

MightyMouseTech · 07-12-2013, 07:44 AM

These look very promising. Was thinking of the H&R OE Sport for a mild drop (1" and 1") without the rake. Looks like these are hopefully a better choice for handling, a little stiffer than the OE Sport with the same drop.

Anybody know the spring rates of the H&R OE Sport in comparison? Are the rears linear rate or variable?

I like the drop, but wouldn't mind a bit more. Hence the interest in the Spec-R springs. I don't have the exact measurements, but I would say its about .25 in front and .50 inch drop in the rear from the M performance suspension. I also have Dinan camber plates up front, so the drop up front is a bit less then it normally is.

Here is a pic with my stock 18s

Here is another pic with my 17" track wheels
