Quick Change Rear Spring Kit for M3 1M

Change rear spings seconds, without disconnecting the lower control arm or dampers and without performing another wheel alignment as long as the ride height remains the same.

This kit not only allows you to change your springs very quickly, it also allows you to adjust the ride height of the vehicle with the springs installed. YES! With the springs installed. No need to remove the springs! Most E82/9X none M or M coilover kits on the market today, you must unload the spring tension to adjust the rear ride height or use spanner wrenches, but not ours!

This kit will work with oem or aftermarket rear dampers.

What is in the kit:

HPA Rear Ride Height Adjusters(Hard anodized)
BMW Sealed Radial Thrust Bearings(used on the top of the main spring)
Swift Main(your choice of rates) and Helper springs(with couplers)
Swift Thrust Sheets(use at the lower portion of the spring, between the helper and the control arm)

$579.95

Order here:

AST 4200 with Swift main and helper springs

These are properly stacked with the tallest main spring possible to provide the most stroke. Some spring rate spiking is also reduced with this setup.

BMW radial thrust bearings(top) and Swift thrust sheets(bottom) are used so corner balancing is possible even with the full weight of the vehicle on the tires.

This is exclusively from HP Autowerks, Inc. No other rear coilover spring setup offers you this function. Period! I am sure others will copy this soon...Some have tried and failed(you know who you are!).

Interesting. Is there not a full front and rear kit? Seems odd to just offer the rear setup.

The front spring is mounted on the damper... So there is no way to offer this for the front.

That may be true, but I've never heard of offering half a coilover kit. It doesn't have to be quick change but you would think they would have a full front and rear setup that goes together.

I don't understand.. This thread is for a quick spring change kit, not for a coilover set...

Yes, it is not a coilover, my bad with the phrasing, but they are providing new rear springs. One would think they would offer some sort of spring set for the front along with it.

We could simply offer a front kit, but it's not going to fit just any strut, this set up here will fit any rear damper.

Front setup would have way too many variations. AST, Bilstein, JRZ, Koni, KW, Moton, Ohlins....60 or 65 mm springs, stock or camber plates, spring lengths and etc.

This is for the track or even street guys who likes to tinker with spring rates and already own a coilover kit. The front is easy swap already with a coilover and there has never been easy solution for the rear until we developed this.

I'm assuming you have a preferred spring length - if you want a ride height adjustment range of ~0.5-1.5" below stock (zcp) what spring length is required? I don't remember the exact length of the rear spring that I have but I can measure its length. Thanks.

No, this kit is full kit only, I don't break it up. What size 60mm springs do you have?

I'd have to measure the length tomorrow. However, if you don't separate the kit then there's really no point because I don't want to buy another set of springs.

Height adjusters are available if that helps.

This kit was developed by HP Autowerks to allow quick and easy track side rear spring changes when HP competed in Redline Time Attack. Your rear alignment will not change as long as you keep the ride height the same.

Harold,

Is the rubber perch located in the lower control arm resused with main and or helper spring? See item 8 in photo?

Harold no worries we spoke via email earlier this week. I was referring to the lower spring pad. You confirmed that it needs to be removed. It doesnt have the right profile to accomodate the swift spring like it does an oem style spring.

Thanks all for the interest in our quick change spring kit. We are currently waiting for a new batch of our height adjusters to be finished(hopefully at a lower price so we can pass the saving on to you). As soon as that is done orders will be shopped right away.
