Yes i agree the DJI is better in terms of video recording, video exporting and so on and so on. EU/Germany, have the tendency to make stupid rules/regulations, hence why the EU versions of the camera is equipted witht the 48deg "safety". If its allowed in the US to blow up your camera i dont see why we arent in EU :-D Ive now had my DJI 4, for nearly 2 years running that script.. Warranty or not - i havent personlly needed that. Ive put the camera into a 50 degree hot enviroment through last years summer- and it took it like a champ. Without the script, the camera didnt even last 10 minutes in a car with aircondition on

There are literally a script you type into the SD card - making it not shutdown. User error is not DJI's fault lol..

For everyday use and some track use, i can recommend the Quaife LSD. But it has a few drawbacks - one being if you have one wheel in the air, it doesnt give you any traction until both wheels are on the ground again - this makes you lose a bit of time around the track, if you are coming out of the Karusell on NOS fx. Is having a wierd feeling until you get the hang of it og know that its how it supposed to feel. Upside - it has no wearing parts that needs servicing, it doesnt lock with a clutch, so it will provide the traction to the wheel that needs it the most using helical gearing transfering the power back and forth. So in corners, it can feel to some extend, having rear wheel stering, because the power gets mostly send to the outside wheel, and the car wants to move further into the apex, instead of having understeer tendency with the plated diff Mperformance fx. The Mperformance vs the Quaife is not a matter of which one is the best - its a matter of what you ideally want and how often you want to maintain the unit. Both are great.

Aah okay.. I wonder how the tüv inspector finds out how the products work number wise, not by how he feels the car drives, but with how much downforce are actually generated.. Do Speed give that info when you buy a wing fx? Or do Tüv makes these tests, with suspension potentiometers? if a company could say, 50kg downforce at 100kmh, 150kg at 250kmh etc etc.. I mean, thats a valid point to a product, that the sole purpose of that, is that it produces x amount of downforce. Thing is, if you produce too much Downforce in the rear vs the front or vice versa, you want to balance this out. But how do you do that, if you don't know how much out of balance you are, if you dont have anything based on numbers, but only a feel? This is the part that i mean, if you dont get the specific performance numbers of a certain aerodynamic part, its just hot air sold in a gold wrap. What i want to say with this, is the parts you buy, maybe do work. But you dont know as a buyer, how effective that is, because you don't have anything to hold it up against. Lap times and corner speeds are not always a good measurement, because both should be better everytime you go there ( in theory) until youve mastered it 100%.

I wasnt asking for the Tüv part :-D Just asking for the validation of the parts working for downforce, ideally with numbers of KG or something force related. I get the Tüv needs calculations too, which makes sense.

But when is it truly valid? Cfd test or real world test with load cells on the car? Me personal, i want to see the real world level of downforce. CFD doesnt say much, because you can alter things in cfd so it goves you the result that you want and that doesnt automatically means it works on the racetrack. Only in perfect conditions where you have the laminar flow going one direction. Fx a front splitter have peak downforce level at ca. 75 mm above ground. Does your suspension go deeper down than this and puts your front splitter closer to the ground, due to the x downforce made at 75mm clearance, you actually induce less downforce, because now you will induce washout and the suspension raises again back and forth. Now you have a condition called porpoising on the front axle. The only company im 100% sure do this measurements are manthey

If S.E or any one who is claiming that their products are really working and are serious about their products. They would road+track test their parts with load cells or ride height cells on the suspension. Then at any given condition, they can measure actual downforce level. I havent seen any proof of any "sub 7" BTG chasing company do this in the tuning scene at or around the Nürburgring.. Most of them just sells a wet fart in a box claiming this and that.

Unfortunately Federal FZ-201 never came in a big size. Definately a super cheap tire that was enjoyed by our group members on the F2x platform.

I ones got an email in return, then never heard from the "shop" again when i laid in the order.

Did you make these yourself? These are very cool.

1 free lap - then catching up with the back markers and a lot of traffic.

I always hesistate when im about to overtake a slower car, id rather lose 5 seconds than losing the car. It is very clear on my videos, especially in corners, that i don't drive like i own the tarmac. I wait till the corner is finished to overtake, only when its very clear that both drivers have seen each other and room is made i overtake. It doesnt matter which colour the number plate are, every nations have idiots behind the wheel.. Even germany has a loooot of them too.. Ive driven on tracks in multiply countries and the worst are the Italians somehow. Closely followed by some UK and German drivers. (Ive driven with a lot of sensible german drivers, so there are no ate towards germans) If a driver have the mentality of he has the "right of way" he is the issue.. Everyone on the road needs to make room for everyone. I have a very fast car, im not the slowest driver, but i don't just push my 1 series up your 100bhp ass and start shoveling you around the track - like i see a lot of others do.. So everyone should self reflect on how their driving standarts are. Staying in the "left lane" even on public road, is a clear sign that you suffer from SDS. It is possible to drive fast in both lanes just like on the public days on NOS.

code brown code brown..

I didnt tell you to go there, i just said if they can register it - somebody else can too.. And tbh.. My cage from them was one of the cheaper things I know what you say and i don't disagree with you. But even people with expensive cars gets that kind of treatment. You can ask yourself, why 90% of their close customers went to the others and why not a single Mechanic is there anymore, from 2023 to 2024.. They just laugh at everyone who doesnt agree with them.. It doesnt matter if you spend 1k eur there or 20k euro.

I mean if 247perf can supply and register them - others should be able to do the same..
