Manage to get only the back ones in today. It was an absolute nightmare! I managed to strip the buttom nut on the passenger side. Luckily I got a mate who has a garage to take off the lower rubber bushing as he had some female Torx bits. With the shock now off he tried using some vice grips but the nut was having none of it. At the end he had to remove the nut using a grinder.

I rear end definitely feels alot more tighter. No more crashing over bumps. Less body roll and less squatting. I'll hopefully get the fronts on next week.

Glad you got them on in the end, was it lower nuts on stock dampers or the Koni you had problem with ? thread is coarse on stock dampers so usually not a problem but is a fine thread on the Koni so do need to be careful fitting the new bottom nuts.

The stock dampers. The nut and threads were completely rusted as was the lower part of the shock. The konis were very easy to fit on.

BTW is it worth getting the front top mounts changed at the same time I replace the shocks or any other parts while I'm there?

Ah ok at least you got them off eventually, fronts wise yes worth doing the topmount while its apart and then its done as does get worn, not that pricey for good quality Febi etc from ebay, or get geniune bmw for about twice the price.

Drove car into work today the long way around (so about 10miles), car does feel a little more compliant and so to me there is a difference between the damper valving on 3series and 1series rear Koni Sports :)... its only subtle difference and will wait till ive got some more miles on various roads etc to confirm but i did same trip yesterday to work on 3series dampers and i would say it definitely feels different today, weather is a touch warmer today but only a couple of degrees so doubt thats a factor.

Not sure anyone else would notice the difference but having tried so many things i like to think im good at picking up small differences, maybe its in my head but will get more miles on them and then i will be able to tell better :D

Need to get my E93 M3 front ARB fitted next :)

Are you going to do anything with the rear end with regards to the arb/lsd? I remember reading somewhere that a stiffer front sway bar and the standard rear makes the rear feel a bit wallowy!

Yes there will be an LSD going in soon and possibly experiment with a thicker rear ARB at some point, its such a bugger to change rear one i want to be 100% on it before i do!, all that said on my last 130i at pretty much identical spec suspension wise but E90 M3 front ARB (little softer than E93 i have for this car) with stock rear ARB and it felt fine, no doubt the Koni dampers help but wasnt wallowy at all, will see how this feels once fitted though.

Last minute unplanned Trackday at croft today so will get to test current setup on track :)

Yesterday i swapped summer wheels on with mpss tyres so will see how it goes, never got chance to fit m3 Arb but as it's very wet at track this morning I'm sure stock will be fine.

Sounds like fun! Looking forward to getting mine on track in a couple of months too - just spent the rest of this weekend fitting BMWP brakes & goodridge hoses :)

A quick one which I hope is relevant to this thread - After fitting my Bilstein B12 kit to my E82, I have a strange clunk/rattle coming from the front when the suspension is compressed, usually when cornering over rough tarmac. I wondered if this is something any of you have come across after changing the struts? I have checked top bolt torque and all arms / bushes etc on the suspension are tight and no play. I noticed one spring seat was slightly skew whiff so I re-seated this properly at the weekend but it didn't help the clunking unfortunately. The sway bar links were replaced with new OEM and also made no difference. I have a feeling it's the Sway bar its self interfering with something due to the increased strain it's under due to sitting lower in the travel - Im going to try disconnecting it when i get chance to test but in the meantime wondered if anyone has any advice and or recommendations for adjustable/shorter sway bar links?

On another note: if anybody wants some brand new Z4 Bumpstops (front and rear), let me know as ill send them for half price. I got them from Cotswold but turns out I didn't need any for the Bilstein shocks!

Part numbers for the bumps are:
Front
2off 31336778545-E85 Z4 bump stop
Rear
2off 33536770350-E85 Z4 bump stop and boot

Cheers, Andy

Clunk sounds odd, ive known bilsteins to sometimes get noisy/clunky with age as top bush wears but yours being new they should be ok, try disconnecting the ARB like you say then you can rule that out fully, misaligned springs plates is common one but if you've done that then rules that out as well.

I never had an issue with needing shorter drop links on any setup on these cars and ive had the Eibach pro springs on same as you, ive seen on some coilovers people have issues when very low but shouldn't be a problem with your setup, but worth checking with them removed to make sure all is good.
