130i suspension overhaul - Er...

Post by ChesterUK » Sun Mar 11, 2018 8:45 am

Hi all!

Bless eLliE, now she's 10 years old and ith 6 digits on the clock, the shocks are spent. I've been reading THETYRANT's thread on http://www.babybmw.net/viewtopic.php?f=20&t=80208 with intrigue but also a bit bewildered with all the options. The set-up I'm looking for would be for comfortable road use only, and often to lug around technical equipment so it can't be too stiff. I did think about going for Bird's B1 but take note about the 'bump stops' needing to be replaced as well, and I really don't want the cost of all this to go north of £1K if I can help it (including fitting which I can get a local garage on to).

If I read the thread right, I'd need to get:

Front and rear BMWP bump-stops

A set of M-Sport stock springs (I'm happy with the standard ride height). I'm thinking this is a good idea to get fresh ones, is that right?

A set of Koni sport dampers

Would I need anything else to complete the parts list? Am I on the right lines here?


Thanks for your help in advance... :)

My 130i has 51,000 on the clock, but the ride is crashy and hoppy by comparison to my recently sold 135i. I can't go any lower than standard MSport as there are several large sleeping Policemen on my commute and I am already touching the front spoiler on two of them...unless I choose to bump over them with one side.

THETYRANT suggested that Koni Sport shocks are superior to the Birds set he tried. Consequently, I'm going for standard MSport springs, Koni Sports and Koni bump stops, M3 LCAs (already fitted) and a pair of THETYRANT's moderate camber plates (that I bought for the 135i before I decided to sell it).

If it's undersprung, I'll revisit and go for a set of Eibach Pros that will only drop the car a few mm over the original ride height, so I think they are likely to provide a similar ride heaight to my 9.5 year old OE springs. The camber plates will also lift the front by a few mm.

I have said car now with Koni dampers and Eibach pro springs. It's a really good balance, and I can stiffen the front dampers up if needed.

I've just replaced the rear shocks on mine for Bilstein B8s and I wish I'd done it sooner. Mine only has 62k on the clock but the shocks I took off were well and truly past it. They were covered in oil and didn't return at all once compressed and the bump stops were falling apart.

I've replaced the lower shock mounts that the bottom of the shock sits in with oem replacements but the upper mounts with Powerflex versions. To be fair neither needed replacing as they were in decent condition but I didn't know that until I swapped the shock over and I didn't want to have to do it twice if they were past it.

The back end now is definitely stiffer but it's much more controlled and seems to soak up the bumps much better but considering the state of the shocks they replaced I'm not surprised.

I've got the rest of the B12 kit to fit so I'm hoping once I get around to doing the rear springs, front shocks, springs and top mounts I'll have suspension that actually works again :lol:
E82 135i N54 - MHD stage 1+, Forge FMIC, Turbosmart Plumback diverter valves, VRSF charge pipe. M3 LCAs + TS, THETYRANT camber plates, Bilstein B12, Whiteline bush inserts, resonator delete, Dare DR X2 alloys, MB Quart QM-200.3 + Pioneer D8604 amp.

Thanks guys. I feel like I've really let eLliE down now. Pogo no more! It's time to sort it out.

So am I just as well getting the BMW bits from the stealer, or is there a better place to go? How about the Koni dampers? Sorry if all this is a bit obvious, but I'm not all there at the moment. Too many stressed out brain cells and not enough beer. Mmm beer.

I bought my Konis and bump stops from Larkspeed - good prices, careful and courteous service and quick delivery. The M3 LCAs came from Amazon...

Thanks for that. I think the part numbers are:

Left front: 857L87411484LSPORT (8741-1484LSPORT)
Right front: 851L87411484RSPORT (8741-1484RSPORT)
2 x rear: 43L82401231SPORT (8240-1231SPORT)

Does that look right? Only reason I'm double checking is they seem to be different part numbers to those listed on the other thread.

Sounds like your on the right track, my current setup is as below and very good balance of road manners/comfort and handling, still sporty feel but more compliant than stock so while you feel bumps they are much better damped out, camber plates or M3 LCA make a nice difference to handling and reduce tyre outer scubbing you get as stock.

Koni sport dampers front and rear (set on soft) - bought from Larkspeed
BMWP front bumpstop - bought from Cotswolds
Koni rear bumpstops - bought from Larkspeed
Stock Msport springs - came on car and in good order
Stage2 camber plates - my creation

If you wanted to keep spend down you could uses Bilstein B4 dampers in place of Konis, these are just direct replacement for stock but much better price.

That's correct numbers, I had some E90 3series ones fitted which are different part number on rears, front same for both.

Thanks Ian, really appreciate it. I'm taking some time to evaluate my position before going ahead with this. There's a distinct chance my annual mileage is going to increase significantly, in which case the 130i is not going to be suitable due to running costs. I'll keep you posted as to what's happening...

I wouldn't you know it, I hesitate for a moment because the smell changed, and indeed it has! I can't justify the suspension upgrade now, and some lucky person will have the opportunity to do exactly as they wish. I'm kinda gutted! What a road going weapon this would be!

So you know the thread that's coming up. Keep your eyes peeled. Thank you so much for the information, and I hope that it's useful to either the next owner or other 130i drivers.

Chaps when doing a refresh like this are there any specific bolts which should also be replaced?

I was happy to re-use all of mine, save for the new top nuts that came with the new shocks and the countersunk bolt set that Ian supplies with the camber plates.
