The difference in handling, comfort and stability is night and day over oem/h&r .Taking sharp turns before the upgrade was unstable and the rear end felt very loose. Now I can make turns with extreme confidence and the overall feel of the road has increased dramatically. I've been in kw equipped 335i and the drive is far superior in comparison. I'm sure the swift springs are part of the reason. I highly recommend anyone making the switch as I am more in love with this car than ever before. The height is ever so slightly higher which in my opinion is perfect!

Thank you so much to Harold from HP Autosport for his excellent customer service and answering all my questions. He is a true gentleman with high level of knowledge in this industry.

Big track guy hater troll and you ran H&R on stock shocks? Pfffft. Lmao.

As I mentioned the height it perfect, the fender is almost perfectly aligned with the top of the sidewall.

KW V1 is just for looks and you can't adjust the rebound. I've been in V2s and these feel better overall. The car feels the way it should feel.
I am curious how this setup has worked out for you after a few ears now? Any regrets?

Linear rate is want you want for more accurate and consistent response.
Hi Harold,

I am looking to add these Swift Spec-R spr Me to my new Koni Yellow's.

Can I just the rear a little hirer using the e30 rear spring pads that come in various thicknesses? 5, 7.5 and 10mm

What do you recommend for dampening settings?

I don't think the E30 spring pads will work, but all you need is some spacers between the upper spring seat and the metal cup/spring retainer.

50% will get you damping that is a little stiffer than stock, some like 70-80% for a firmer ride. Front is easier to get to so you can start at 50% and go from there.

What spacers do you recommend to raise the rear end then?

I was planning on dialling in the Koni's to 1.75 turns from stiff on the front and 1.5 turns from stiff for the rear. How does this sound?

Thanks,

You need spacers that are no more than 3.75" in diameter and less than 1/2" thick. Too large in diameter they won't fit inside the metal cup and too small the spring may become unstable. 1/2" spacer at the location will mean nearly 1" increase in ride height so you shouldn't need anything taller than that. Keeping it under 1/2" will also ensure that the spring does not come out of the metal cup.

This is what I recently did to raise the back end. Is this not a good idea based on your comments? A number of people on here have done this modification to raise the back end slightly. I used the 5mm e90 spring pads.

5mm should be okay as it is less than 1/2", the springs will still be contained.
