And now Springs. Normal ride height please. I'm guessing m sport is more expensive as well as lowered
I'm guessing I can use b6 with standard Springs on m sport specd car

Zeds? I got two of them... :o
I'm sure you have your reasons..

As for the 16" thing, I agree with lots of what he said, I just wanted to see how far he would go to explain his " get a z3" comment, and I was waiting for the 2.0 folk to join in as many started on 16" and some still are probably, certainly my 2.0 is at this moment.
It's perfect case of style over substance, and I agree 18" look better than 16", but do they work better? Absolutely not. :D

The issue you have is the knackered shocks, to demonstrate before I replaced all mine my car (M Sport suspenders!) would catch on road humps. I swapped out all the shocks for B4 and initially had Eibachs on (so lowering 15mm). Apart from the improvements to ride etc the car would catch on road humps far less. I put this down to the fact the knackered original shocks had next to no resistance in them when I took them off so with the new ones the car compresses less at the front when you hit a hump hence less catching. Ride wise a switch to SE springs from Eibachs (which are supposed to be more comfy than the M Sport ) definitely improves things as does running M Spec tyre sizes.

B4 is really want you want shock wise, its what Euro etc sell too (although they may be branded slightly different). they are all a twin tube design gas shocker like 99% of road cars come with from the factory these days. The B6 and B8 are mono tube and give a much harder ride, harder than standard, they're up rated 25-30% over M Sport. Ultimately mono tube shockers are a better design but twin tube is more than adequate for road use. plenty of info on the net to demonstrate the differences between the two.

im sure my springs are shot as it soo low at the front. the shocks stiffen up if you bounce on them a couple of times
so its springs and shocks together at the front im sure i need.
im seeing bilstein @ carparts4 less for 106 each and sach springs for 68.66 that seems reasonable.

am i right in thinking they will just bolt on my m sports specd car and replace the m sport shocks and spring job done ?

Be interested to know as technically the fronts shouldn't fit & were never offered as a option for 3.0 Z4s.

when you say the front shouldnt fit, do you mean the 16" WHEELS wont fit on the front of thr car ?
i think i saw somewhere that 300mm disks were ok which i think i have, but like you im only curious because of my soggy bottom, and not because i prefer 16" - now im aware i have suspension problems i will address those first.

Thats correct.
The 16s were intended for the less powerful models that needed smaller brakes.
Daresay a spacer might aid your quest. Rears probably fine without.

Less power requires smaller brakes therefore smaller wheels
All the answers are there.
Thats not to say more power equals more pleasure , I've had good times in both my 2.5s

my mechanic has raised a couple of questions,
1 will i need to get new posts/turrets if i fit standard springs on ?
2 whats is the cost differance if i fit the factory m sport suspension as opposed to standard fit at the front. ?

In relation to 2 - you shouldn’t pair M Sport suspension on the front with SE at the rear.

Either go SE on all four corners, or go M-Sport all round.

I presume M-Sport will be more expensive.
