In the States You can find used Gt4s with low miles for about 120k.

A BMW worthy of it since the F80. Hopefully more driven than parked.

On the road at slow speed it might be negligible, but on a (bouncy) track driving at those levels an experienced driver can feel the difference.

Yup lowering springs increase spring rate and need more rebound damping to control the rate.

And if I'm not mistaken, it seems to have a square set-up, so probably /30 instead of /35 front tires (hence the non-starred PS4S), making the ride even stiffer. Worst decision ever.

He certainly was not fan of the normal PS4S on that M2, he said the car definitely needed more grip.

They are definitely better than standard issue 4S spec

Stiffer sidewall and better rubber compound so it’s definitely the tire choice I’d be running

The electric parking brake function is supplemental to DSCi, though. There is no restriction placed on the number of pistons by DSCi, but the standard design for parking brake activation used by BMW and VAG (including some Porsches) uses a lead screw driven by a motor on the caliper. Using anything other than a single piston with a floating caliper is a lot more complicated and is better replaced by a dual caliper design used by, for example Alfa Romeo, where the parking brake has it’s own dedicated caliper on the same brake rotor.

Kinda annoys me the way he drives on the ring. I know he drives on the ring like every day but he is so so aggressive , it’s pretty dangerous. Would never let him drive my car there. Don’t really get the people who let him thrash their cars. It’s like letting someone take your wife out for a night

I don’t mean this in terms of driving the car hard, more so in terms of how aggressive he is passing people with no space or when it’s unclear they actually see him or not. He is often upset in videos about people not getting out of his way but some of those situations he has put himself into by riding up their persons butt when they don’t really have much room to get over.

How many laps at the ring do you have?

I haven’t checked the G87, does it still use that? Or is it using the new DSCi 4 wheel parking brake?

It certainly has motors on the calipers, you can hear them activate. This is the parking brake actuator used directly on the M2 calipers: https://shop.bmw.ca/p/BMW_2023_M2-Co...216870567.html

I drove the Ring right after the Spa F1 race last year. It was incredible experience.

I do not see excessive aggressiveness from Misha's videos. I do see other drivers not doing a good job of checking their mirrors though.

From a redundancy perspective with a manual transmission, it likely is needed in case of DSCi failure in a parked car, as failsafe mode for the motor driven parking brake is "brake-on". From an i-series car or potentially auto-only ICE & hybrid vehicles with transmission pawls/locks, perhaps it is not needed. Bear in mind that outside of North America there are still quite a few manual versions of different BMW cars being produced, once the manuals have disappeared from all model lines, then the motor driven parking brake will probably be retired.

I don't think he drives aggressively at all. And he waits when he needs to and even thanks/compliments the drivers who signal intentions.

The thing is, when the speed differential is high, you *know* you can pass a car before they can change directions and block your path. I think that is what you think is aggressive from the videos. But in fact, it is safer to blow by a slower car, than to try to pass with a lower speed differential. With a lower speed differential it takes a lot longer to pass a car - during that time they can veer into your line or not be able to hold the line as you are passing in a corner.

Just my 2 cents.

After market springs do one thing!! Lowers the car for street use. That’s why when you start pushing hard the car becomes unstable. The MP Has kit is the one is made to work with your stock dampers. Yes the KW looks the same but the springs have different tuning. The people who want the slammer look will also avoid the MP and buy some jank junk. If your going to track your car all the time..: just stay with the stock springs or buy a full coilover suspension.

[Lappy]

You guys are blaming the springs and saying the bmw adjustable springs are better? The problem arises when you remove travel and end up on the bumps tops. Doesn't matter what springs you are on really as non of them are all that stiff to begin with. What's the first thing mhas owners do? Slam the car as low as it goes and complain its too high lol.

Yeah screw that

Very close to being out of warranty as well

[baron95]

I specced MP HAS on my build for port install - but I'll be honest, I'm a bit nervous about it, as there is virtually no before/after track reviews or lap times. The best I was able to find is a G80 guy who did some laps on 3 tracks stock, then came back with more camber and KW/MP HAS and did laps and was ˜1.5 sec/lap faster.

Problem is that it was his first time on the tracks stock, then second time with MP HAS, then you have the camber addition. Hardly an apples to apples. He does like how the car handles on track with KW/MP HAS, specially on transitions, though.

So I'm rolling the dice, and none of the tracks I run is nearly as bumpy as some of the N-ring sections.

As to KW vs MP HAS, I see no indication that there is any difference other than the color of the springs. Just like they didn't bother to tune for the G87, they probably didn't change a thing for the G80/82 either. They didn't even have different versions for a G80 xDrive to a G87, two very different versions of the platform.

I think they just slapped an MP label and called it a day. Which is OK - KW is a competent company.

But who knows how well it will work.

Surely there has to be a vendor out there with both kits that can actually compare.

I would also like to know what springs this car had on it. Personally I will never get as much out of a car on a track as this guy, but I am interested in a slight drop for ascetics. I am wary of making the ride too harsh though, as the ride in the F87 I test drove was quite harsh so I went with the G87 for the adaptive dampers.

The factory g87 setup is very good.

If interested in not making it handle worse and wanting to lower you’ll probably have to wait for proper coil overs, at which point the ride will be far more firm than factory.

Just getting around to reading this thread. Lots of conjecture around lowering a car. In this instance the car does not have star spec MP4S tires which will alter the cars handling and dampening. Also, they mention springs but not what type. If they are not properly matched to the dampers it will handle like shit. Furthermore, if they didn't also install shorter bump stops the car was likely riding them and again it will perform like shit. Installing springs is not the same as using a quality HAS kit that comes with shorter bump stops.

You can still get full suspension travel with a high quality HAS kit with the added benefit of lowering the entire cars center of gravity and will outhandle an OEM setup.

I was at the Ring on the 20th and 21st.

I rented a track prepped F87 DCT and it was great.

I also saw this car rolling around the area.

Personally, I do believe black is the best color for the entire BMW lineup at the moment.

Also they all sound atrocious.

BMW was hosting an M Driving Event and my god I had to rev the M850i I had as a rental to stop the pain LOL.

That is my "hope", so I specced the MP HAS on my build.

But I have seen no data to back this up. I hope you are right.

Do you have any experience driving a G8X car before and after a MP or KW HAS install on track?

But he is no longer racing professionaly, so I guess he also doesnt fit your criteria. I dont know a professional race car driver who is also a youtuber. May be there is one out there of course but your criteria is pretty harsh.

Misha is a professional, but not a professional to a degree you perhaps expect. But he is pretty good I think in terms of feedback, works with sherman bmw, worked for Rimac, worked with the Mantey Racing. His CV is ok I think, better than, say, most of Youtube car reviewers from Chris Harris (good) to just good car reviewers like Harry's Garage. Wouldn not dismiss. You probably can get a wide variety of these dudes reviewing the car - from Doug Demuro to Misha to CarMagazine to Camisa to whatever and get some kind of picture. This comparison to M3-M4 is pretty good. They ran that car as a taxi on the ring, have a decent thought of what M2 would "feel like".
