Description
Do you already own BC Racing Coilovers and want to upgrade them to Swift Springs, or do you want to change your spring rates?
Swift Springs' innovative designs have made us a staple in the performance tuning world. Our products are the result of over 90 years of experience in industrial spring manufacturing. Our engineers have spent countless hours developing and re-developing our springs, in order to create a product that is light, durable, and compliant, while still maintaining linear spring rates.
Many enthusiasts will swap springs from brand to brand with the only noticeable difference being a stiffer or softer ride. But what if a spring could offer a noticeable increase in traction, smoother weight transfer, better ride quality, lower tire temperatures, and a more predictable feel? The engineers at Swift have taken that 'what if' and turned it into reality.
All Swift Springs are manufactured using (H5S.TW.) which is far superior to silicone chrome steel and allows us to wind our springs with less coils, resulting in reduced un-sprung weight and increased stroke
Since the metric system is used widely in the sport compact and road race market, we have introduced the metric line of coilover springs to reduce confusion and to better cater to our customer's needs.
Whether you are looking for a comfortable ride for your commuter or a more aggressive setup for your race car, we have the right spring for your application!
Note: This is for one pair of two (2) springs.

QUESTIONS & ANSWERS
Ask a Question-
I have d2 coilovers on my 8th gen si, they’re too soft in the rears and I’m looking to go pretty stiff, do I just measure the inner diameter and overall length along w the spring rate I want and order like that?
We have all of the Swift sizes available on our main website at www.springrates.com. That way you can select the proper size there.
-
What is the spring lenght?
The spring length varies. It's determined based on what coilovers you have and the options you choose.
-
Does the swift spring fit on my d2 superlow in a 1998 honda crv
You'll need to measure the inner diameter and provide that to us along with the spring height and spring rate you need.
-
Since it says that its two pair. So I would also need to purchase the ones for the rear?
It's one pair, so a total of two springs.

Hello, I have BC Racing BR Coilovers on my 2007 WRX TR. I believe it came with an 8kg/6kg spring from the box. I would like a softer combo with 6k/4k for street (or even 6k/5k). Could you advise on a combo (street duty car daily driver) and could you be tell me which springs would fit my coilovers? Thanks Leo
We generally don't recommend going with a softer spring rate because they're determined based on the weight of the vehicle. If you want a smoother ride, we recommend going with Swift Springs as they will ride smoother in comparison.
-
Which springs should I go with? Im looking for something to make me really low and super stiff. The coilovers I am currently using are the maxpeedingrod brand coilovers. Thank you.
The best option is to go with a full set of replacement coilovers such as the BC Racing Extreme Low Coilovers to ensure the proper struts are matched with the springs. Going with a shorter/stiffer spring on struts that are too long and not valved for the rates will be detrimental to your ride quality and performance and will greatly shorten the lifespan of your coilovers.
-
Will these be the 5in springs ?
You need to specify the BC Racing Coilovers you are using on your vehicle for us to send you the appropriate diameter and length.
-
I made a mistake getting these godspeed mono ss coilovers the springs to soft for me I like that stiff ride so I'm wondering if I can change the springs for stiffer springs
We can sell you Swift Springs but the struts won't be valved to match. This will shorten the life of your struts and also cause poor ride quality. You'll need to provide us with the inner diameter of the springs, the spring length, and the rares you need. However, we recommend maybe selling the coilovers and purchasing a set that is valved to the spring rates you are looking for.

Will these fit my race lands 2003 Subaru Forester
These are only for the BC Racing Coilovers.

I have a 2017 Toyota Camry se I just got the br bc coilovers installed but I want a smoother less bumpy and bouncy ride I was told to look into swift springs to upgrade my question is what spring rate should I be looking for because I’m clueless when it comes to that and I’d definitely would like to order it from you guys
If you'd like a smoother ride, then definitely go with the Swift Springs. Your best option would be to go with the default spring rates for that vehicle.
