So Birds kit Vs Adaptive with motech/Birds springs?

When I spoke to Partridge they said i’d Be very lucky to find a used M135i with adaptive as few spec’d It on earlier cars.

Shame the used search on BMW’s site is so sh*t, makes searching for a car such a pig and it’s ruined with the latest update.
For B58 F2x - BMW's MPS is now available for both adaptive [springs/bumpstops] or passive [springs/dampers/struts and bumpstops] as a warranty friendly option.

Can't comment on Eibachs, but H&R and Birds B1S springs work very well with M135i adaptive, even better if you can the VDC re-flashed to latest FW. My car went in for rogue front end rattle - initially they thought it was adaptive dampers so latest FW flashed. Sharpened up damping responses a lot but didn't get rid of the rattle. New ePAS rack was the fix.

Best combination is 1) adaptive M Suspension. 2) then take it to Motech and get them to fit their Hybrid Eibach springs.
The progressive nature of the springs mean the ride feels totally standard on normal road driving... the minute you load the car into a roundabout
it just corners flat.
To follow on from TRL's point above, on my M135i the adaptive damping behaviour changes to suit, when upgrading springs - provided the drop isn't too much else damper stroke would be too short. The Variable damper control (VDC) has learning capabilities to suit load conditions [1 up, low fuel, empty boot --> 5 up, full tank and full boot] and it appears it can cope [within reason] with changes to springs too. Passive dampers wont and also known to be sh!te quality.

With either spring set, my cars initial "brittle" road manners - when cruising or pushing on - on stock springs was gone and this is despite me having Birds / H&R F&R ARB's too !

Top tip - I didn't fit shorter bumpstops on my car [1st with H&R sport springs then with B1S springs] but in hindsight I should of. The oem dampers would have worked better for sure.

My BMW MP springs come with shorter bump stops.

Ironically the rears are more of an issue than fronts.....

I'd suggest getting a pair of rear MPS or rear 5 series e60 bumpstops before Monday....

The MP lowering springs only come with shorter front bumpstops, no rears.

I very rarely travel with people in the rear so not so much of an issue I hope.

Manc,

My understanding is F2x MP suspension bumpstops [OE part # 33502411196 aka "Genuine BMW Auxiliary Damper Kit"] is for F&R as per both table and close up photo below...

Enjoy the new car today knowing, should you need to, retrofitting b/stops on rear dampers is a lot easier than doing same on front struts......

Re rear bump stops, Phil at Cotswolds triple checked for me and the BMW picture is wrong - you only get the front bumpstops in the kit - not rear.

Someone on the FB page who has H&R springs on his M135 has showed the condition of his rear OEM bump stops which shows how much they are being relied on... I would recommend shorter bump stops for the rear if lowering

Paul,

Agree 100% - according to Realoem - MPS b/stops for M140i part # is 31336859768 and clearly states this front only.

Manc

Reads like you have bought the above part # hence why only 2 b/stops. You are going for shorter Motech springs all round, hence the part # I quoted is an older MPS part # but includes all 4 bumpstops.

So if fitting the Motech Eiback springs, what bumpstops are best for both the front and rear? Seems confusing as Mike from Motech said that the standard ones on the M140i were fine.

My car is passive not active. Does this change anything with the bumpstops?

I'm surprised when I hear this from a supplier but I guess it's somebody elses car and the problem doesn't manifest itself immediately..

Here's a pic of the bump stops from a car with Motech Eibachs fitted posted from facebook page

Picture of my rear bump stops with MPS springs and adaptive dampers. Car has done 2600miles so far. Should I take a picture jacked up?

Like the OP I had an Audi A3 Sline Black Edition 2.0L Turbo diesel (albeit not Quattro) on 18" wheels. It's a good car in terms of maximum cabin space for minimum external dimensions. But the suspension! Talk about harsh. And the 2.0L had a very abrupt torque curve (or, rather plateau) - it was easy to stall if you weren't in the right gear. This is the only car I've ever owned where I regularly bottomed-out the suspension. Frankly, any 2 Series will be a better ride. And the 6-cyl engine will be a joy.

I went for stock suspension on the replacement 330d and then opted for Adaptive on my current M235i.

If you do a test drive, make sure it's an adaptive and try out the Sport vs comfort modes. Also make sure that the dealer has set the modes to change suspension and gear shifts, which are user-adjustable.

Hello All,

Firstly - thanks for all of your inputs!

I did as suggested and got out and test drove 3 different M140i's in different specs. One with passive and run flats, one with passive and proper tyres and a final one with adaptive and proper tyres.

Whilst I didn't immediately feel a night and day improvement as some suggested im sure that's down to not being used to the car and not really giving it a big push as it was only a test drive! But I can say I did feel the difference in the M140 that was equipped with adaptive, so much so that I'm now in the final stages of ordering my own M140i WITH adaptive suspension :D

Thanks again guys
