Pure Engineering - Made in Germany. Speed Engineering thinks new in their ideas, developments, designs and products. Speed Engineering's standard is the extremely high demands in motorsport, which is reflected in every work step, whether in motorsport or off the race track.
PRODUCT INFORMATION
Air Duct Inlet
In order to transport the air to the outlet of the brake ventilation, a suitable inlet is essential. The F8x M3/M4 does not have factory inlet ducts in the front bumper like the M2 Competition. What your car has, however, are 2 coolers on the side behind the bumper! So why not use the existing airflow efficiently?
In order not to let the air swirl around randomly in the wheel arch after the cooler, Speed Engineering have developed a duct that can be installed with minimal effort and leads the air around the wheel and a connection via a 40 cm long hose (per side) to the outlet connects. Tests have shown that this does not create any significant back pressure behind the radiator and in the event of extreme speeds and increasing pressure, the ducts do not present any obstacles to the escaping air behind the radiator.

Important Information
The different models vary slightly in the wheel position, coupled with different chassis geometries and wheel and tyre combinations, it is impossible for all variants to be covered. In the worst case, the wheel could hit the ducting when the steering wheel is fully turned (which should only be the case when parking), which cannot damage the tyre. In this case we would ask you to do without the last ¼ of the steering turns.
The required brake hose diameter is 51mm (not included). The matching brake hose and hose clamps are optionally available to order. A complete front brake cooling kit for the F8x M3/M4 is also available here.
Suitable for F80 M3 Sedan, F82 M4 Coupe and F83 M4 Convertible (incl. Competition, CS and GTS) models.

Inexpensive doesn’t mean cheap.
Color: Black/Orange
After 10 months, zero complaints. Well, I got rid of the horrible NATO strap 🙄. That’s a personal preference. Easy to swap out to whatever you like. Keeps accurate time meaning it’s the same time. I’m not micro analyzing it and the seconds gained/lost. It has a confident look and feel and makes you feel good when wearing it. Sure it’s not high priced but it’s not cheap. Very comfortable, light and not unincumbered. If this is what you’re looking at, you’d be satisfied. Great looking, durable and simple watch. Full confidence.

Budget Seiko Prospex this is not
Color: Black/Orange
Bought this as a cheap work watch, but I guess all the budget went into the solar technology.
No date adjust feature, gotta crank the crown over and over to adjust the date. (Also no screw-down crown, but that's expected at this price)
Fake diver bezel. Lol why? Cringe as heck. Should of just put a compass bezel on there instead tbh.
Cheap plastic crystal, scratches and mars just by looking at it.
Okay NATO strap. Falls apart quickly, but it's easily replaceable with a better quality one.
Decent lume on the hands, but none on the hour markers even though it looks like there is.
Looks cool.

Simplicity
Color: Black/Orange
This watch was received exactly as advertised. First off the watch is economical compared to other watches that advertise the same details. I will say that I have gone through numerous Luminox watches only to be disappointed. This watch fits the bill. It does have solar cells which mean it needs to be exposed to light to keep running, not a problem. Three minutes under my surefire light I am golden. The bezel doesn't rotate actually no big deal for me. I have always required that the bezel moves not anymore after having a bezel that rotates I use it next to never. Here's why, the more I rotate the bezel the more the numbers wear off. The strap on the watch with the catches for the strap are perfect. They actually hold the watch strap in place in lieu of like other big name brands that just flop and slide. As far as everyday use goes this watch is my go to. To be honest I have purchased three. This is the only watch I will wear moving forward, yeah the glass my scratch but even the big names like the Luminox I spoke of earlier scratches too.

Favorite watch / solar
Color: Green/Green
I'm partial... I have bought Timex my intire life, they no doubt make the best watches... They take a licking, but keep on ticking is there old commercials.. True.. Great quality, keeps going after many year's... I never bought a solar watch from them prior I have to mention... It should hold up I'm thinking like their battery watches, I hope so. My favorite watch, I own a handful. Watch looks better in person... Downfall, they are trying a new band out of recycled plastic, I don't like it as much as the older bands it's soft, but feels a little strange...
