my z4m rear custom diffuser

[jrainlay]

Nice enhancement to an already incredible looking coupe! But you might want to consider painting it orange to improve visibility. oke:

There is a black plastic undertray that fits between the silencers and which is attached to the OEM rear diffuser section of the rear bumper. If you attach some vortex generators such as these http://www.ebay.co.uk/itm/VORTEX-GE...arParts_SM&hash=item35a81d8535#ht_1932wt_1165 to the black undertray, you would achieve a similar subtle visual effect. They would also have an effect on flow of air passing under the car. The cost would be £22

Or you could buy this http://www.ebay.co.uk/itm/New-Suzuk...arParts_SM&hash=item2a059782df#ht_2185wt_1165 and cut it to size and attach it to the black undertray. Cost £36.50

I like your creative thinking

Or an even cheaper solution: http://www.ebay.co.uk/itm/4-Colors-...es_CV&var=&hash=item460402cbe2#ht_6302wt_1141

Only £1.73 each including postage. Spray them matt black and it would look like a proper diffuser.

What are the blanks on the sides of the front and rear bumper for?

 

[daz05]

They house reflecters that are fitted on the North American cars. Dubs has colour coded his.

Car looks awesome, well done.

What are the blanks on the sides of the front and rear bumper for?

I think the American Market cars have round indicators in the bumpers, sure someone will confirm

There are also circular running lights in the rear bumper. Both detract from the car's appearance. Best solution is to "delete" them which means substituting color matched replacements. Just ordered front and rear sets for my car from IND Distribution. Cost = $150.

Absolutely stunning. Any chance of some clearer pics of the diffuser.

Your car is gorgeous 8)

 

[dubsesd]

here is one that isnt taken against a dark ground

 

[ga41]

Not feeling it to be perfectly honest. I don't think it actually looks bad but i also don't think it looks particularly nice. Rest of the car looks ace though. Now you need to get a big brake kit to round it all off.

 

[exdos]

Although those aftermarket cills are called "aero" cills, because the lower part is angled inwards, IMO they look more likely to let more air under the car, causing lift, than the OEM cills.

 

[dubsesd]

The aero sills are oem. The small rear diffuser is purely aesthetic and doesn't let any less or more air under the car. I never removed the oem undertray, just installed the diffuser.

 

[007MCoupe]

so this is purely cosmetic?

 

[dubsesd]

Yes. Just a small aesthetic part.

i likey, very nice

 

[Swiftly]

Very, very nice, fantastic looking car and love it all

 

[Aliv6]
