Coilover Recommendation

[Epsilon]

The Eibach Pro-Street is currently on sale at Tirerack for $1373. Haven't really heard too many bad things about them. If anything, some of the track folks changed out the springs and mentioned they were on the soft side. They also come with new endlinks.

Nah I don't think that's correct. You can see here they're "progressive wound" and not "linear". Also it even states they are. Having mixed "progressive rate" and "linear rate" isn't really advised.

I'd post a photo but it keeps showing errors and won't allow.

I mixed it up, it’s the front that’s linear (340 lbs), rear is “up to” 565.

Price has also gone up considerably. They’re not worth $2k imo.

I'll have to vote for Eibach prostreets. They're super comofrtable compared to my previous forunate auto, and also in comparison to BC racing and SGT as well as as a couple other coilovers ive experienced in the E46 M3s. theyre very affordable and you can even drop the car low enough to tuck tires.

Yes, and the varying diameter of the wound coils are a good clue to a progressive (non-linear) spring.

Another data point: I went with KW v2 and its an OK setup. I'm not impressed with it nor do I hate it. I really like stainless construction but that's not normally at the top of list of priorities for suspension. In my research on old M3F, I saw more comments suggesting look at the other options than recommending the v2's and this turned out to be a fair presentation in my view.

PSS10 rear springs are linear for whatever it's worth. Not that I'd consider them forgiving in any sense of the word.

So he was the original purchaser with receipts and you're saying Bilstein would not warranty his leaking shock?
Was it leaking from being in an accident/damage or normal wear and tear.

Yes, lifetime does not usually mean lifetime on most things. The part that had an issue was not a part the make for rebuilds, buy the whole set again was the only option.

With "linear rate" springs and camber plates it's not going to be as forgiving as the Bilstein PSS10 kit. The Dinan springs and "Dinan" Koni Sports he has now are one of the best Street-Sport combo out.
Not saying he would hate this kit you linked. Just from where he's coming from and wanting mostly the height adjustment it doesn't seem as good a fit as another.

^LOL, i like how you started off the first sentence.

Just to roll around town and get groceries, I'd go with MCS, at least 2-way.

If mostly what you care about are aesthetics (sounds like) i.e. you want a more slammed look than what you have now, why not just heat/bend/cut the coil to appropriate static height to make sure you can fit and not rub your preferred wheel/tire combo or get a shorter spring (damper piston travel will accommodate and by the time they blow you will replace them). I think people jump to coilovers way prematurely because this one dude and this other dude got them and they like them. Coilovers in most cases are synonymous to people wanting power seats when they buy the cars because they are going to adjust them.....maybe once in the lifetime of the car on day 1.

Just my rattle.

Sure was. No way I would go with them after that experience.

BILSTEIN are Lifetime Warranty (to original buyer). They'll either replace or rebuild. Have not ever heard before about them not rebuilding. Pretty sure the place that rebuilds them in NA is in San Diego(maybe used for Koni also). Bilstein and Koni have had the best warranty in the industry.
But good to know about your friend's experience. Was this claim of his under the Lifetime Warranty to OP?

Comes with camber plates and everything else.

Ground Control single adjustable and TCKline SA are your starting points price-wise. Next step up is GC/TCK double adjustables or Ohlins R&T. Do you have a budget?

Also, out of curiosity, what makes you say your ST kit is shot?

Budget: $1-2k

Thanks for the input, I'll start browsing the net for prices and reviews based on your recommendation.

As for the ST's, driving under uneven surfaces, bumps, or potholes produces a thump/compression noise from the shocks that I have been able to reproduce by standing on the door sills and rocking the car back and forth. I have really enjoyed the ST suspension up to this point, exact replacement is an option.

My initial plan was to send the kit to KW for a rebuild, but the prices are nearly the same as purchasing a brand new kit, which includes end-links/springs...

N00b tryingto work out my next suspension setup.
My car had pre-installed ST Suspension kit, https://www.turnermotorsport.com/p-2...it-bmw-e46-m3/

Needless to say its shot. I want to replace my suspension during my rear end refresh.
Street use only, but I do plan on doing light track duty.
ECS is running a 20% discount on the Konis right now @ $650; https://www.ecstuning.com/b-koni-par...kit/e46m3koni/

Any recommendations for springs? Ground control has a nice eibosch kit paired with the Konis, drop in ready.
Should I replace the end lnks and or the camber plates? Ground control has plates for $400 but I doubt it fits my application.
Front and rear Hotchkis sway bars installed.

I'd like to retain the height and street friendly ride.
Anyone open for a call? I'll quickpay you enough for a decent twelve pack, need input from someone more knowledgeable

Here's my current setup:
