I'm under the understanding that These Swift Spec R springs were made to use the Original E92 Bumpstops?

Thanks. I was hoping someone other than a vendor would confirm it. Looks like most people are still putting Other Bumpstops in. I just bought these springs and we're putting them in now - so I hope they're right!

You'll be riding on the bumpstops, not a good thing. Depending on how you drive, you may not notice it. From my experience with lowering springs compared to the wonderful stock suspension, if you cut down your travel, you lose grip and anything over rough pavement is unsettling. It's best to retain oem travel, it'll give you more grip and a better overall ride...hard cornering and power down grip wasn't as good as stock. Keep in mind, BMW designed a great all around suspension, the stock dampers/springs are a beautiful match. Lowering springs change the character of that match. It'll be firmer and initially sharper on turn in but there's more to it than that.

My observation has been the car exhibits increased body roll when you increase mechanical grip from wider tires/stickier tires.

I agree in general the M3s suspension is fine.

I finished the installation earlier tonight. It needs to be aligned, but so far the car rides like stock. It may be modestly firmer but I honestly can't tell right now.

do these really benefit an otherwise stock suspension? Never thought sleeves or springs did anything to gain performance (if anything hinders it).

I installed mine and used e36 m3 bumpstops. Also shaved down guide supports about .2". Still think i need to shave a bit more to get it back to factory travel amount for best ride. I do bottom but only on big bumps or dips. Go to track tomorrow so will see how it does there.

So after reading all of the post its still unclear to me if there is any benefit to using e36 bumpstops with these since it was designed for oem bumpstops?

The only way you can answer this for yourself is to call Swift USA and ask them. That's what I did, and I determined my own preference would be to change the stops to increase travel that I'm losing by lowering the car.

Which bumpstops did you go with. Both front and back? I'm planning on putting eibachs and are they lower than these swifts? Car hasn't come in yet but want to do it all in one step.

No, E36 bump stops aren't required. Swifts designed these springs with proper rates, NOT progressive rate that are too soft for a lowered ride height(reduced bump travel).

Thanks! not required, but will it help increase travel further or it would make no difference?

Anytime you use a shorter bump stop you are increasing compression travel, but it's highly unlikely you will need the additional travel.

Eibachs are not lower than Swifts. I used E36 bumpstops in the front, rears you don't need to touch. I recommend you call up Harold @ HP Autosport as well, I think you should really consider Swifts vs. Eibachs. Eibach drop is basically the same height as the Competition Package.

+1. I went with E36 bump stop anyway (only an extra $40), figured while I was in there, might as well.

Really happy with the ride height.

My opinion is yes, go with the e36 M3 bumpstops. Even though they say they are not required, I went with e36 bumpstops and shaved my guide supports down about .2". The ride is very good and handling at the track is greatly improved. If I could go back I would shave about another .2 to .3" from the guide supports to just to give me a little more travel (currently i only have about .2" of travel up front versus the .5" they have with stock ZCP setup). Only 2 issues I have now are some occasional bottoming out over large bumps or big dips in the road and car does get slightly unsettled when hitting mid-corner bumps due to the fact that it's leaning hard on the front bumpstops when you're really pushing it. My local track is smooth so i had no issues there.... mainly just notice this on the road... off ramps, etc.

Just my 2 cents. I'm very happy with the Swift Springs though. Great product if you want to improve handling while keeping EDC.
