Are their any tech related disadvantages of getting Coilover springs? Maybe the Bilsteins from... Bavauto? Has anyone had these?

The largest disadvantages of coilovers are a decreased ride quality and they require an alignment everytime the height is adjusted.

they are great for a track car, but really not as practical for a street car.

I have the Bilstien PSS. They actually ride pretty well, the spring rates aren't that bad for street use, around 400lbs/in. The improvement in handling is incredible though.

Also, Skawful, if you're bottoming out a lot, why not trim the bottom out bumpers a little to give you more travel?

I also have the bilstein PSS coilover kit. I LOVE IT! Obviously it is a drastic change in ride quality but, it really isnt that bad. And for me to say that, someone who lives in MA, one of the worst states for roads i think, is pretty good. And the only time i have bottomed out, was when i first was driving with the kit after i installed it, and i bottomed out on a speed bump, cause i was going too fast, but that was my own stupidity.

Anyways, this kit is great, and when combined with the Turner Motorsport sway bar kit, or any kit, it is amazing how the car will handle after. I am amazed at how fast i can take turns now with little to no body roll. It is great and this is my everday driver also. So this kit would not be bad for street use. The PSS9 is more of the track use setup with the adjustable shocks. Anyways, MY OPINION is get it if you can!!

this was a big thing for me, i wanted to get coilovers and wasnt worried about ride stiffness, however since ive gone to a shock spring combo, all i can say is id hate to drive with coilovers, the current set up i have is very tight and rough, but hey i wanted it that way. mechanically, you stress all the suspension components much greater, and things internally seem to get loose. i never really noticed that i had to tighten certain things up untill a week after the new suspension

Yes, but one thing I've noticed with all products regardless of application, is...you get what you pay for. When I had Koni adjustables on my last car, it was stiff, but never loosened or induced premature failure on any undercarage components.

My experience with coilovers was a firm ride but never overly harsh. Due to their supperior construction and build quality, they are a cost effective improvement.

But there is an alingment re-adjustment required whenever the height is changed?

Personally, I don't think that coilovers aren't any different compared to a spring and sturt combo, aside from the height adjustability thing.

I'm pretty sure that if I went to H&R race springs with Bilstein Sport struts, it'd actually ride harsher then the Bilstein PSS coilovers.

If you look at the rear setup of of a e36 coilover kit, it looks identical to a non-coilover kit, minus the adjustable spring perch.

Also, regarding coilovers, certain wheel sized require spacers to clear the front spring perches/adjusters.

I don't know how you can say the ride is worse.....where are you guys driving? Plus you're driving BMW's, not Cadillacs :P

If you were to get the Bilstein PSS setup and slap in on a 325 for example, and get a set of 400lbs springs and Bilstein Sports and put them on another 325, drive each car without knowing which car has what setup, you wouldn't be able to tell the difference.

i totally agree, my ride is just as stiff if not stiffer than the PSS series of coilovers.

ummm Nelson i drive downtown, nothing is worse than downtown toronto when construction is everywhere. :lol:

but seriously the ride is by no mean "worse" ....... i love the feeling of taking the corners hard, but its un-nerving when the corner has huge potholes or undulations in the road. the car hops and can get kinda scary at a decent speed.

Be able to tell the difference in handling or ride or both?
