    • The controversial Mercedes Formula 1 DRS rear wing design legality being re-assessed by the FIA

      Teams are in a huge fuss this year over how Mercedes designed their rear wing believing it is not legal and giving Mercedes-Petronas an unfair advantage. The results do not show a big advantage for Mercedes thus far but the FIA is being pressured into assessing the design and ruling on whether it is fair or foul. Now, Mercedes built the wing system with approval from the FIA to begin with so where is the beef? We think Mercedes should be applauded for their ingenuity and if other teams have an issue with it they should start working on their own design.

      We will keep you updated on what happens but for now the system is legal. The other teams will likely continue protesting in hopes of a ruling that outlaws the DRS wing.

        Erm, "work well" and "fade" don't go together in one sentence when talking about brakes Click here to enlarge

        Pretty much every M3 which is driven on a racetrack has been upgraded with a proper BBK. Which is just a statement of how bad the stock brakes are. Dwell in P-car forums, and you *may* eventually find people talking about swapping brake pads, and that's about it!

        I don't see why not. The brakes stop incredibly well. The problem is with doing this over and over and over. The issue isn't the stopping power, it's fade.

        New lines, pads, and rotors are all that are necessary to get the M3 track ready. BBK's are trendy.

        You're better off replacing the caliper as well, while you're at it lol. The floating piston design is crap and not suitable for a proper sports car. I would venture that even M3 buyers prefered to spend the $7k on something else than a "trendy" BBK.

        With BMW now entering the DTM, some kind of techology transfer to production models would be nice. Like the "Cecotto" E30 M3. But current DTM racecars are very far from street car specs. Hmm, there still is the Z4 GT3 programme or the M3 GT2 ALMS cars to get inspiration from Click here to enlarge

        Well then you get a BBK. But the cost is huge versus doing what is necessary to get what you have track ready which can be done.

        Smart ones. That is likely why I am going all out with my motor and everything else and the brakes are more than enough for me.

        I feel Porsche customers get the best transfer of racing technology to production models. BMW doesn't do this very well and definitely not as well as Porsche.

        Yeah, I tried other pads and rotors on the stock braking system. Two trackdays later I was in the market for a BBK Click here to enlarge

        And the M3 brakes aren't much better on a track. Better pads may be ok for occasionnal track duty, but not enough for hardcore users.

        Anyway, I hope you'll treat your car to more than 1/4 mile passes. Would be a shame if you didn't track it properly. Isn't the M3 all about the handling? Click here to enlarge

        I'm trying to find it but there is an upgrade out there that uses the stock rotors I believe and adds race pads, new lines, and calipers that eliminates the need for a BBK many of which won't even let you run 18's which any hardcore track guy should be doing.

        Mine will hit the track probably. I need to do drag racing first but after that I'll probably want to take the BMW Nurburgring record just because.

        This drawing shows Mercedes clever 'double DRS' system in its entirety. Air is sucked into holes in the rear wing endplates (left inset) which are exposed when the DRS system is activated. Using similar channelling (highlighted in yellow on car profile) - but in reverse - to that utilised two seasons ago for the now-illegal F-duct, the airflow is routed into the beam wing, across the top of the deformable rear crash structure, along the side of the engine and then through the chassis (centre inset) before it exits through the front-wing pillars to blow onto the front-wing flaps (right inset), stalling the wing, cutting drag and boosting top speed

        Pretty awesome design!! I hope Schumi can grab a few victories this year!

        If Rosberg outperforms Schumacher all year I think Michael knows its time to hang em up.
