Had a look and to be honest prefer Stuartinzg's Z.
I was thinking of black grills too but after seeing yours I have changed my mind.
I like how the rear wheels sit but not in black.
 
I thought about Quads but for me it didn't fit the style - that's why I got these X6 tips made to fit. Although when I get the eisenmann race I may even weld off the eisenmann ones and put my X6 ones back on because I think they just work so well, and still bmw !

Can't work out if those V1's are lower than my Eibach

Liking those tips and diffuser combo - looks sweet. I'll take full and propper pics and shove it all in the pending write up. My current set up isn't on the lowest settings, the KW's can go quite a bit further on both front and back but I'll need to be careful with the front wheel grazing the suspension, so I left it a little higher for the time being. I will probably drop it a touch more after I get everything else done.

Just had a closer look and your front gap looks to be a finger and a bit, mine is just under a finger. KW1's I would highly recommend. Handling is great, zero boat rolls and tighter steering.
 
I'm on EDC so I don't want to swap that out to get KW's, I have different settings, stiffness etc on a button. Softest setting is very nice, Sport+ is rock hard. I'll be swapping the front struts for M3, they bolt on apparently.

Have a look at this thread

I also did the mirror caps and few other things - you can see here. This was before the eibach

Gret stuff. Nice 360 there paint looks clean. I was going to mention the KW3's having various adjustable bits for the EDC but I could be talking out of my ass.

Here are a couple of pics of the car on Install day with the guys moving it around at the garage so you can see the lowering at a more normal angle. You can see what I mean about the front needing to come down a touch, slightly more then the rears to get that supper sporty aggressive stance. It's close, but soon it'll be bang on after i've bedded the springs in and can try the extra clicks. Sorry about the filters, trying to mask how filthy the car was in attempt to avoid getting flamed :P

I had a 5 day paint correction and ceramic protection done so it was better than new.

kW just delete edc, the edc is the adjustable shocks so if you put kW on then obviously it doesn't exist anymore... and they made a kW for later cars which plugs into the button but not for the z4 only the 4 series I think

Just wanted to clarify something on th exhaust.


Though the Eisenmann Quad isn't advertised as a Cat Back exhaust, the actual parts seem to suggest it is. It is described as "Complete with connecting pipe, Intermediate Silencer"

http://www.eisenmann-sportauspuff.d...ntermediate-and-Rear-Muffler_B526900764_2.php

From the other forum, after installing the exhaust the following was removed from the car:

The image looks to be removing what looks like a intermediate resonator or a secondary cat box. I checked this on real OEM.

So, from the above, can I deduce that the 3.0i came a mid pipe silencer and not with secondary cats and that the Eisenmann will replace this with a resonator? OR is the Eisenmann "Silencer" another word for cats?

I thought all modern cars came with two sets of cats.

Picture of the system of which looks Identical to the 35i.

Thanks very much for the help! Hope it was clear.
