Standard Z4MC Discs & Shockers

OEM equivalent Bilsteins are not better than stock.

On what metric do you base that statement exactly?

I second that, the Bilstein replacements in question are better

Did you compare Bilstein to old Sachs suspension or brand new though?

OEM equivalent Bilsteins are not better than stock.

Bespoke engineering and testing.

Not to mention it will be easier to move the car on if it’s on OEM suspension.

I suggest you sit in a car with brand new M suspension vs one with OE equivalent Bilstein/aftermarket suspension to discover for yourself.

Oh right, just your opinion then, no actual facts to back up your statement, how surprising. :roll:

This a forum of course it’s my opinion

Bilstein shocks are stiffer than Sachs - fact.

Car will be easier to sell with a refreshed OEM set-up as opposed to an aftermarket - fact.

The only 'fact' I can see here is that stiffer/softer does not equal better/worse. :lol:

All sorted just pushed the button on the following - all prices include VAT & delivery:

OEM discs & pads (front & back) from Harry Fairbairn - £610
BC Coilover kit from Corby Motorsport - £725

I have the best of both worlds in the PSS10/B16 kit.

I can have it rock hard for the track, and soft for the road. Even the hard setting isn’t as fidgety & unbalanced as brand new OEM kit.

 

[Attilio]

Harry Fairbairn prices bring total down to £1,700:

Front Discs EACH: £142.80

Rear Discs EACH: £95.40

Front Struts EACH: £250.00

Rear Struts EACH: £154.50

Front Springs EACH: £105.80

Rear Springs EACH: £106.10

Didn’t even know about these guys!

Cheers!

Enjoy!
Glad we could be of help

Are you doing all the bushes as well ?

Just wanted to come back to you regarding this question now I have purchased the BC Coilover kit - when I spoke to BC racing they indicated there was nothing more I needed to purchase to swap-out the standard set-up.

Should I still be looking to purchase the replacement bushes or are they only required with the Bilstein kit - excuse my ignorance here just want to make sure I have everything required before I book the car in for fitting?

 

[mmm-five]

I’d be putting new spring pads/top mounts on, as they’ll be past their best too.

I’d also be checking the condition of suspension/steering/roll bar bushes whilst I was in there.

Very impressed with the service from Harry Fairbairn in Kirkcaldy - the full set of discs and pads arrived this morning via DPD

Yup exactly. The monotube dampers that Bilstein usually use are much higher spec than most OEM shocks, certainly far superior to the stock Monroes. Whether you like the individual fitment is another issue.

OEM shocks are Sachs...

Shame the Bilsteins are not inox like KW though. :?

This doesn’t really concern the Bilstein B6 as it’s simply a yellow painted non adjustable damper.

Also, having had experience of Bilstein, KW, Ohlins and Nitron adjustable suspension, with regards to corrosion in daily use etc. I’d say the Nitrons were the best and all of them still require a level of user upkeep to maintain correct functionality.

A friend who worked as a senior chassis consultant for BMW (and Lotus, Ford amongst others) and worked on the Z3M, E46 M3 and E39 M5 would beg to differ. Being able to work with such high quality suppliers such as Bilstein was a privilege according to him and very rare in the automotive field.

He was reluctant to work with BMW later on, as he was getting fed up of having to engineer in a 'sporty ride', for no dynamic benefit.

Anyway, it's all opinion, go with what you like.

deligthed to hear that: I am very impressed myself as they delivered to my local indy.

Best of luck!

Coilovers have arrived so now need to book it in for fitting along with the new discs

 

[Monster666]

Are there any drawings of where all the bushes are located? Or are there kits available? I'm thinking of treating my '06 roadster.

I used them for my discs - you should be amazed by the improvement when fitted. The smoothness has returned to my car now that the balance has been returned. The discs are big lumps of metal and mine hadn't worn evenly.
