Re: Which shocks
B6 & B8 Sports Dampers - Bilstein High Gas Pressure Monotube Shock Absorbers. Uprated by around 10-15% on standard damping the biggest difference between these units and their twin tube rivals is their ability to combine a smooth ride with excellent spring control.
B4 Standard Spec dampers
Made to exceed OE spec where a twintube damper was originally specified these high quality units make an excellent upgrade for a road car and also work well with moderately uprated suspension springs.

Re: Which shocks
I can't find my email, but give bilsten UK an email. Explain what you want and the details of the car. See what they come back with.

Re: Which shocks
I don't really see the need, are the answers not here?
B4 - their standard spec equivalent. No worse than OE and at a much more reasonable rate.
B6 - uprated shock
B8 - uprated and shortened to suit lower springs
B12 - B8 shocks with matching Eibach springs.
I think the real question for the OP is how much he wants to spend.

Which shocks
Evening all. Reading the above I think I may have fitted the wrong rear shocks to my Z4MC. Bought a full set of B6’s from Germany and fitted the other day. I got the part numbers from demon tweeks and cross checked before ordering but now I’ve discovered the UK bilstein website I’m confused. I’ve now contacted Bilstein UK for some advice as I’m getting annoying knocking noises from the rear now, thought it was a loose bolt but I’ve rechecked the torques. I’ve got standard BMW springs (its an M so I’m guessing they’re lower than non M??).
Strange though that from their website http://www.bilsteinsuspensionstore.co.uk the part number I’ve fitted 24-141680 should be ok, but also part number 24-104906 would also fit?
Are B6’s the wrong choice for my z4mc?

They don’t do a Bilstein B8 for the M cars annoyingly so you have got the most updated shock bilstein make for your car without going the coil over route so you should be fineNev wrote: ↑Sat Jan 20, 2018 10:33 pmEvening all.

Bear in mind the above discussion is for non M cars which have different suspension, regardless of M sport or not.Nev wrote: ↑Sat Jan 20, 2018 10:33 pm I’ve got standard BMW springs (its an M so I’m guessing they’re lower than non M??).

B6 is correct for the M, as hops says there is no b8 option. Correct part number for the rear is as you have fitted.

Cheers for the replies guys. It certainly puts my mind at ease.
I’ve got Powerflex rear too mounts (the purple road spec ones). I took my rear shocks off today and checked them over again and refitted. I discovered the rattling noise I’m getting when driving is actually the Powerflex top mounts that are rattling against the car body despite being torqued up correctly. Thinking about replacing with new OEM mounts unless I can find a fix for it.

I have turner rebuildable mounts on the back of mine.
Highly recommend them

Do you get any rattling with those turner top mounts? The Powerflex ones I’ve got have a extra reinforcement plate between the body and the top nuts and wondering whether that could be the cause. I’ll have another mess with them tomorrow.
I’ve ordered new Powerflex RTAB’s and hoping they don’t give me any bother...

I had these Turner mounts and they were terrible. Knocked from outset and when I took them off one side had an oval inner metal sleeve. You can see in the picture that it's too short compared to the thickness of the rubber and despite being torqued down it doesn't hold together well as the rubber is too stiff to compress that much.

I'd stick with OEM as they were fine on removal at over 60k miles and didn't make a sound. I replaced the Turner with Meyle HD and they were still a bit clunky.

There are 2 types of turner top mounts for the rear the ones above and the more expensive re buildable ones. The re buildable ones are the ones to get, I also had the ones above and they knocked like mad!
I have only ever heard good things of the re buildable ones
