Why new cars may start using drum brakes again - And not only because hybrids/EVs can recuperate

Hi guys,

I think it is interesting how the new Audi Q4 is using drum brakes again - like a 1950a Mercedes 300SLR. And it only seems to be a trend in the car industry, for obvious cost cutting and EV reasons. But actually, there is new regulation that very soon will be implemented, that car companies/supplier are already bracing for. I made a little video unpacking why drum brakes aren't necessarily worse than discs, and what the new regulation will mean for cars starting MY 2027.

Hope this is entertaining and clears up the reasons why a lot of us think "new-cars-are-getting-worse".

For trackday beginners and the technically curious: how anti-roll-bars affect handing

Hi guys,

I made a little video explaining how anti-roll-bars change the dynamic behaviour of a car for track use. If you're new to tuning cars for track use or are curious, this 6 minute video hopefully helps explain in a technical but understandable way.

Cheers!

Why a GT3 RS Cup 2 is not the same as an "ordinary" Michelin Cup 2

Some people drive the Michelin Cup 2 on a GT3 RS and immediately recommend the tire to all their friends with different cars. But the Cup 2's made for the GT3 RS are "only" made for the GT3 RS, and is absolutely not the same as a standard Cup 2 you get at your independent tire fitters.

I made a little YouTube video explaining how modern tires are developed with manufacturers, and the video goes into chemical compounds a bit as well.

(GT3) Explanation of 991 MacPherson vs 992 Double Wishbone advantage geometrically

I made a little YouTube video explaining the "geometric" design difference between the MacPherson construction and the Double Wishbones (DWB).

The video is a little technical but very easy to understand and explains the geometric advantage the DWBs have which the Mac doesn't, namely: softer effective wheel rate but with the same controllability.

It'll talk about: Centre of gravity, front roll centre, and my personal experience/opinions with/on the 991 GT3 RS and the 992.1 GT3.

Hope this helps.

991 GT3 RS Rear Axle 'Bumpsteer'

Hi everyone,

I used to set up cars for the Nordschleife and many owners of 991 (especially Mk1) GT3 RSs complain about bumpsteer or having the feeling that the car would be very unstable at the rear. I made a little youtube video explaining how exactly the rear wheel steering works, and how to set up the 991 3RSs for track use to fix the 'Bumpsteer' - it is a bit technical but kept quite simple and straightforward for everyone to underatand.

Hope the explanation helps.

Trackdayers: How much would you value OEM engineer/development driver advice and tips?

Hi guys, I'm from the Nürburgring and we have noticed that a lot of people specifically around the Ring value advice from OEM engineers/development drivers. We wanted to ask whether you guys, the trackday crowd, would use a QnA platform where verified engineers and development/race drivers answer your questions.

Would you guys use this platform and what kinds of questions would you ask us? Just collecting thoughts at this point.

Thanks

EDIT: sorry that this sounds salesy (not helping that englisch is my third language), I'm not selling anything and just wanted the trackday crowd's 2 cent on whether we value these expert's thoughts.

How likely is an Iran-Deal while Trump is still in office?

Someone on Polibear said this following an article from CNN: https://polibear.com/post/6a0602b851dfbd4ddc2c98ca

Since Iran may not even have a centralised government capable of peace-talks on a national level (Trump killed some Iranian leaders US diplomats were in contact with - smh), how likely will the Iranians just wait it out and not touch Trump's peace advances? Game theoretically, it makes perfect sense not to deal with the western evil that is in their eyes Donald Trump, delay the process, and get a better deal with the goal of forcing all US forces out of the middle east. Iran must be thinking about that long term.

Edit: I think the majority of comments don't have a positive outlook for this. Btw. here is a word cloud for how people think of the US (& Israel) attack on Iran: https://polibear.com/wordcloud
