E46 M3 Suspension

Recommended Posts

What up!

Looking at a refresh of my suspension / dampers as I am assuming they are toast after 180km, (hard to know how bad they really are right?)

I've read a lot of international forum suspension posts, but interested in the 'local road' feedback and what everyone is running?

I'm trying to keep it affordable, simple and comfortable for a daily. Options that seem to be be most popular I am considering:

  • Sachs OEM replacements (comfortable, but am I missing the opportunity to 'upgrade')
  • Sachs with Eibach or Dinan springs (lowered car compromises?)
  • Bilstein B12 kit AKA B6 dampers with Eibachs - apparently the B6 alone will raise the ride height - I don't want that. 
  • Koni  (with maybe with Eibachs or Dinan Springs) - getting dearer 

Keen to hear anyones NZ experience / opinion. 

Cheers

I think its worth the money to upgrade the shocks konis or bilstiens, as the stock shocks are not renowned for their longevity.

To save money have a look at importing from demontweeks in Wales as its usually the cheapest source even after taxes and shipping.

Good tip - I'll check them out thanks!

I'm not too worried about longevity - what is it, like 5 years until they would need to be done again? (It's probably been 17 to this point!)

I currently run the Eibach Pro Kit on my M3 with stock shocks - it's a mild drop and not impractical at all in terms of ride height. My stock shocks only have +/- 70k on them and still feel as if they're in reasonable order hence I haven't upgraded those yet. If my M3 saw more use and spirited driving I would be upgrading the shocks sooner rather than later however. 

I did purchase a set of Koni Yellows through George Stocks for my E46 Touring and that made a big improvement to the ride. I recommend them if you want to avoid the cost and hassle associated with the coilover option. The only problem with those is that rear rebound adjustability is a nightmare if you intend on playing around with the settings. 

Unfortunately in NZ there aren't many options for locally supplied coilovers other than BC's. As mentioned above, Demontweeks, Schmiedmann etc would likely be your best bet if you're after a decent set of coilovers.

I went Koni Yellows with stock springs, didn't want to really lower the car given NZ's roads. The Koni Yellow's at full soft are equivalent to OE. I've firmed mine up slightly and am very happy with the setup.

Eibach springs for the E46 M3 are (IIRC) a 20-25mm drop in height. The springs themselves are firmer than stock, and ride better. I supplied a couple of sets of Eibachs to people a few years ago.
I wonder if the Koni adjustment is something they expect you to do before fitting - the rears in particular are a bit of a pig to get to/hold correctly to adjust once fitted.
If you want a 'budget' coilover, look at the Bilstein B16 (PS10) kit. Sooo much better than BC Golds or anything similar.

👍

I love the Koni yellows on my Mercedes. Given the choice between those and Bilstein B8s, there is no competition - Konis every time. I've used yeloows on several cars and always been very, very pleased with them.

This is the set up I think I am going to go with. Koni + OEM springs. 

$760+$140 USD shipping form ECS tuning. 

It's annoying FCP Euro don't stock them as I have never been pinged on import with them. 

I've emailed George Stocks twice with no reply - if anyone knows a better place to source, please let me know.

Cheers

George Stocks is overpriced and not good with warranty claims in my experience.

They have (had) good engineers but the guys I knew who worked there have left.

Had a bad experience where the engineer rebuilt some shocks only to have them leak, and then they tried to charge to fix them.

Thanks again. Didn't get pinged for import duty or GST. 

I've noticed some places seem to fly under the radar. ECS Tuning is not one of them, been charged every time.
