Does the aero works one come with the oem tabs?

I'd be tempted by the slimmbones one. Good thread with pictures over on m5board from memory

Not sure. Folk go on about having to trim the tabs and use double sided tape which is not acceptable.
Don't know if that's still the case.

Just fitted rear carbon diffuser, roof spoiler and lip spoiler to my M5 from Schiedmann

Parts are good quality finish but the rear diffuser needs a little filling on the screw tabs in order to fit flush. The tabs will click in across the centre alright.

CA dont do any E39 diffusers

If you don't know it's best to keep it buttoned.....plus Black asked for diffusers etc that's why I quoted him.If he had asked specifically for a carbon finned one I would have said no and to get one from Slim like I did!!!!

I think you should learn how to speak to people with some respect instead of telling folk to "keep it buttoned" like you would to a young child!

I had a look on CA website and could not find any under

Front Spoilers, Rear & Roof Spoilers, Bonnets, Splitters, Diffusers etc section and they did not have any listed.

What's the difference between the aerowerkz & slimbones, they both look very similar to me?

Also where can I buy a front lip from, similar to the exotic tuning one?

Hi,

 

Aerowerks is/are their own company and Slimmbones is his own entity as he's well known on the M5board as an enthusiast who makes his items to order. 

 

There's nowhere in the UK that sells a front lip spoiler that similar to the ExoticsTuning item. There is one available from another US specialist though, and I'm able to source one if you wish from them. Have a quick read on this thread for ballpark/approximate pricing

Hi Dennis, thanks for the above link. Very helpful

Unfortunately I've mistaken another lip for exotic tunings, the lip i was referring to is this one.

Do u know anything above the above lip!

As for aerowerkz vs slimbones, what's the fitment like on both and any ideas what it would cost for a rear diffuser shipped and duty paid to my door in edinburgh, Scotland

Many thanks

Dennis your lip looks amazing especially with the black highlight or is it carbon?

Anyway not sure it will look as stunning on a darker car. I like it but my car is black and £600 is a lot for me to spend on a lip.

Looks much improved on stock tho and not bad moneys as well. Only thing that's questionable for me would be fitment and quality

Hi,

 

Mazi - The lip spoiler I have is of very high quality, the first 30/40% of the items were snapped up very very quickly by a lot of the USA guys running M5's and also those with other E39's who abolsutley demanded as best quality for fitment and materials as possible. I think my one is numbered like 68 out of 100 and when it arrived I was very impressed with it. The 'tip' is genuine carbon fibre. There's a number of dark colour E39's with this item fitted :)

 

Black9 - the one you refer to is the Hamann replica/copy that's been available for ages and from many places etc. Way too common for me ! but it's the one many who do want a lip spoiler choose as it's a cheapy! As there's been many different manufacturers of them and none are branded as such, you might get one that fits quite well or one that doesn't and will need some time fiddling around to make fit nicely.

 

Cheers, Dennis!

Mazi, How did you get on with choosing a rear diffuser? Do you know if the ones from M Style are any good, they seem cheap, but maybe that's for a reason.

Not seen them. Link?

Not chosen one yet.

Quality of fit seems to be suspect on many.

Could easily spend over a grand on front lip and rear diffuser. Can't really stomach that.
