FOR SALE BMW Z4 M Brake Cooling Kit

For Sale
This kit replaces the non functional OEM brake cooling ducts and it uses the same mounting points. Horn relocation/rotation is needed to fit this kit and some cutting in the inner part of the wheel arches for the hose routing. The front backing plates replaces the OEM ones and in the rear you have to modify the OEM backing plates.
The kit includes brake cooling ducts for the front bumper, backing plates, funnels for the backing plates and brackets. All metal parts come painted and hardware such as bolts/nuts/washers are included in the kit, the backing plates come pre-assembled and ready for install. 3" fittings up front and 2" in the rear. Hose and hose clamps are NOT included in this kit.

"MOTK made me aware that there's an OE block off cover for the wheel arches (From the 3.0 Z4) you can buy for cheap. The OE one in plastic cost around 5-6$ each side.

I have 2 kits ready to be shipped right away. 15 kits sold already without any complaints so there's no doubt this kit works and fits nicely. :thumbsup:
 
I have backing plates fitting BMW Z4 now as well (1 hole needs a slight modification), I can make something for the front bumper if anyone is interested.
 
I think there was something in the news that might impact the track season this year, can't exactly remember the details.... :?

Don’t think it’ll be too bad. Can imagine it’ll be one of the activities that’ll carry on before too long due to the minimal social contact. Hopefully anyway!
 
Amateurs tracking their cars will be pretty high on the risk list, so it'll surely be one of the last things to get approved.
 
Not so sure about that, I doubt there will be guidance on what specific events can and can't run when the lock down is relaxed. It'll be more generic such as large open air gatherings etc and down to the TDO's to decide whether they can safely run, which I'm sure they'll push for as they will want the revenue as will tracks. There's rarely any major incidents, certainly less than on the roads on a daily basis so can't see that being an issue.

They seemed to be sensible with how they were run just before the lock down with briefings etc. so hopefully that'll carry on and they'll be back in business but we'll see of course.

Hi,

Any chance you make this kit for E85 to replace the front fog lights?

Cheers

I have backing plates that fit the standard Z4 but I have no fog light replacements right now, I'm willing to make some if you want to take some pictures and measurements.
 
Hi,

Thanks for the offer, that’s great. What price are you wanting for the whole kit vs just the backing plates?

The backing plates will be the same price as for the Z4 M.

"- Backing plates and funnels is 1000 SEK which is about 82£."

Since the fog lights on the standard Z4 are smaller than the intakes on the Z4 M I'm estimating the front bumper ducts will be 1000 SEK/82 £ as well. So that'll be a total of 164 £, shipping and fees not included.
