Any Swift Spec-R spring experiences?

Firstly, I apologize for posting this in the general space, but the suspension forum gets little traffic.

I just had swift springs installed on my '15 f80.



I'm noticing a lot of "floating", bouncing, the front end feels dipped downward and when I'm driving the car (this is my daily), it now seems like the hood (aka seeing the hood surface while driving) is just moving up and down a ton more than it was at stock. It's stable at 30-70, however at 0-20ish, it reminds me of how my '95 Honda Accord on weapon-r coilovers felt back in the day. Hitting the bumpstops, just bouncing around.

I'm currently on 437 19" wheels, standard tire sizes.

Thank you to any and all for insight!

I have those springs on my M4 and don't notice any of the bouncing motion you mentioned. It's firm and responsive. Do you have the M Adaptive suspension? I generally keep mine in sport mode.

I have them on my M3, haven't felt anything like that-as peeb said they're firm and responsive.

I've had nothing but amazing things to say about the Swift's on my 18' F80 ZCP. Maybe you can dry having the ZCP damper settings coded in or the m3 CS shocks coding done. I absolutely love mine. I switched from Eibach V2 and the ride is night and day better and absolutely perfect ride height!

well the front is has been lowered more than the back now... so of course its going to feel more raked. the stock car sits ok in the back, but the front has a ton of wheelgap to prevent scraping. Front -1 inch, back -0.4 inch.

i did have cs edc, not sure if the dealer reset it back to stock with the spring install. will check tomorrow. i have a little bounciness feeling too in comfort at low speed. sport mode feels good though.

Why did u which from v2? They're supposed to be stock like and modest drop.
Swifts are supposed to be harsher than stock?

The V2's never felt in sync with the ZCP shocks. It rode wonderful for a daily and was great, I just like the stiffer feeling. The Swift's just brought more "M" to the car. It's totally civilized and the drop in the front gives the car a more balanced look. I will admit, I also went back and reviewed spring rates and on paper the Swift's are a better match for the car. So for civility, by all means go for the Eibach, no issues at all. If you want a sporty feel and a nice clean drop, the Swift's bring the car to life.

Sounds like something isn't installed correctly. There shouldn't be any bouncing

500 or 600 on the V2's. 1500 on the swift. Zero noises from either set.

Thank you for the replies! I forgot to note that this is a non zcp, non edc car. It's gotten better over the past few days, I think it was an issue of getting used to it. the suspension is notably more rigid, which I'm fine with, but coffee in the cup holder is completely out of the question anymore because that shit goes flying out of the cup at any bump.

I think another aspect may be because I haven't had it aligned yet. Possibly? Pic below

I hated them on my 16 F80 comp. I went to KW HAS and never looked back. I just installed another set on my 18 CS and love it!

No problems here on same wheel setup. Rides alright more bumpy but itís what I expected. No floating or anything you said tho. You might have got it installed wrong. I did them myself in my garage and made sure it was right. If you do install it improperly I have heard of the similar things you have stated. But idk for sure if thatís your problem.
