Even Bilstein B4’s with lowering springs are a HUGE difference. Actually takes on bumps and isn’t jittering everywhere. The brace I didn’t even notice a change.

[@oceandrive7283]

Yes, I used to have a Z4 Coupe and most owners eould do the Bilstein B12 upgrade- this was B8 dampers and Eibach springs. This worked better on track but, for fast road use B4 dampers along with Suplex springs worked better on the road- you had some compliance that wasn't there either the B8.

[@wobs5]

Nice one Reg. Agree with all you said and have done all these mods. Rear x brace will fit all F20/21 I believe. I've got a 4 door (F20) which didn't come with one and I thought it was the 2 door LCI2 that got them but I could be wrong. Res delete on a PPF car shouldn't cause any problems. I put a Milltek non res on my PPF car with no CEL issues but although some improvements in sound, not a patch on the pre PPF cars. . Agree with what you say about B8s and Eibachs. Good improvement. But having tried several suspension variants, best for me by far is Birds Bilsteins and springs but cost a few £££s more.

[@kenflaherty9106]

I got the bilstien b8 dampers and mmr springs £799 Also the underbody brace £169 from performance m. My mate who is a mechanic fitted everything for £400 So £1368 in total but the car maybe twice as good as it was before so money well spent. Thanks

[@roadreg1820]

That's an absolute steal for the transformation.

[@SebHUK]

Love this video! The side by side comparison of you bouncing in the seat to show the difference in the suspension was surprisingly affective :D Now to save £700... Maybe I shouldn't have gone Stage 2+ first haha

[@roadreg1820]

There’s still time Seb! 😁

[@slashed4548]

hey what do you need for stage 2 m140i ? is it just a downpipe and air intake?

[@SebHUK]

@@slashed4548 No intake needed for any stage, stock is great. For stage 2 it's just a decat or a sports cat. For stage 2+ its decat/sports cat & high pressure fuel pump. Both easy DIY jobs

[@slashed4548]

@@SebHUK Thanks mate i recently got a remus non resonated cat back system and wow what a difference to the sound do you think a sports cat down pipe will make much more noise or is it more for air flow?

[@SebHUK]

@@slashed4548 when I bought mine it already had a rouble res deleted, but i wanted to go stage 2+ so put a sports cat on it. It's a LOT louder now with the sports cat. IMO it's a bit too loud for me so I'm going to look at having a resonator put back in haha

[@ChrisBrown-]

Hi Reg, I’ve finally but the bullet and bought b8 dampers as I already have springs. Going to get underbody brace and get them fitted at the same time. And your videos and comments convinced me😃. Did you get xhp gearbox map…?

[@roadreg1820]

Hey Chris - wow great news!! Glad my video helped you. I haven’t got XHP. Engine and gearbox are stock other than air filter and exhaust!

[@NickthaGeek]

For anyone watching this vid. Ignore the suspension recommendations here. Performance M are selling the b14 coilover kit for £899 on sale. Use EVILGT10 and you get them for £810 or there abouts. Absolute bargain. Got them recently for mine which was a game changer. Also, whilst you are there, buy their powerflex handling package for the rear subframe and diff inserts. Go with the track black ones. Although they are hard, they give pretty much zero nvh. Also whilst there... get the scorpion res delete. With the same code you get it for £338 Removes both res. Not too loud. In comfort its almost stock.

[@roadreg1820]

Hi bud, thank you for watching. This was filmed a while ago and prices have changed. Just a heads up. Thank you 🤩

[@roadreg1820]

Also, I’ve had the B14’s on my old E46 330ci. They’re very good! I had to replace them after 3 years tho! :(

[@roadreg1820]

@@NickthaGeekmany track days. They wore out.

[@NickthaGeek]

@@roadreg1820 ah. Ok. Fair enough. Their not really considered ideal for track so that sort of makes sense. For a daily they feel perfect. Maybe a little firm..... but not too harsh. They atleast do their job not rather than the terrible oem stuff.

[@aforandi]

White is the best colour. The black M Performance decals beneath the doors look excellent on white, obviating that side profile blankness [similarly a light grey M2 yesterday looked rather like a picture frame without a picture]. The wheels: any colour but black -- keep these for winter tyres -- so 436M Ferric Grey. Red leather & a sunroof would have bin nice. The point of the three-door, apart from having more usable doors than the five-door, is instant convertible status at any speed, with the sunroof, because the windows are large. And such a [fully-loaded] M140i is rarer than most Lamborghinis. I've only ever seen one. Tending to complete conversion to gentleman driver, maybe *unlined* leather gloves, no perforations, elastic, straps, studs, just plain thin leather. Chester Jefferies used to do them but went out of business, because people who should have bought from them didn't.

[@craiga3277]

Great video, I’ve been considering getting Bilsteins and a brace for my stock M140i, but I use my car as a daily driver so still worth doing? Or will it be too firm ie best used on track? 🤔

[@roadreg1820]

Definitely worth doing - it improves the ride comfort of the M140i tbh. The quality of damping is so much nicer on the Bilsteins.

[@craiga3277]

Good to know - thanks!

[@stevenpragassen5601]

How do these compare to KW Sport dampers for comfort? I use mine as daily driver too. Thanks.

[@nallanw4329]

Hi Reg Great video and points. I thought the PPF cars had just one resonator and obviously the PPF itself?

[@vollcare4076]

Powerflex rear subframe inserts also cheap and worth the install

[@roadreg1820]

Good shout

[@coenwag]

I had a OEM under body brace, upgraded it with the Ultraracing brace. Difference is huge. :)

[@dauwg99]

Really?! I'm so glad I went straight for the UR bracing. It's rigid as hell.

[@NickthaGeek]

I doubt it.... with that l bracket lounting points on that ultrabrace. Lol Made to look strong then has a worse design mounting points.

[@coenwag]

@@NickthaGeek wel I really feel a big difference.. I didn’t feel anything from the OEM one..

[@NickthaGeek]

@@coenwag fair enough. Sometimes placebo is a thing. I can tell you though I definitely noticed the difference from none to the oem one. Each to their own.

[@darkblueturbo]

Is that off the self bilsteins or the Birds specific ones? I had some juicy Bilstein on my classic Impreza back in the day with Eiback springs and they were amazing.

[@roadreg1820]

Off the shelf B8 Dampers with Motech spec Eibach’s. They’re slight lower then standard Eibachs that come with the B8 kit. Very nice! They make a big difference.

[@101TheKMan]

Awesome video Reg. The underbody brace made such a big difference! Thoughts on the rear subframe inserts? Any plans to give them a go?

[@roadreg1820]

Probably not for me, as I’m happy with the balance between comfort and sportiness. If I was doing more track days, then I would consider

[@vollcare4076]

@@roadreg1820the yellow rear subframe inserts don’t really have much negative NVH impact

[@andrxito]

I really liked how the car felt after fitting a strut bar as well! Give it a try, it's cheap. I've already done coilovers, underbody brace, strut bar amd lighter wheels. It's simply a different car now

[@coenwag]

Guys, I have full powerflex black bushings in the subframe and purple in the diff. Difference is huge. The noise is hardly noticeable, it’s just same kind of increase if you put cheap tyres or if you drive on really rough tarmac, sort of the sensations that’s is, totally something to live with. I also hear 0,0 diff whine. Car feels soo much tighter!

[@andrxito]

@@coenwag How hard is it to swap the bushings? I feel like I will only change them when I get an LSD in there

[@davidhaygarth648]

Does the brace fit other 1 series such as the 120i ? Looking for a decent quality hatch spoiler as I reckon it really needs one to beef up the rear. Just looks plain at the back. Any ideas ?

[@roadreg1820]

I think it does. Can’t see why it wouldn’t. I’d go Maxton for the rear spoiler. It’s a nice size and not too in your face.

[@LynxEng]

good but... 2 series isn't above the 1, it's the saloon version of the 1. 1 is hatchback, 2 is saloon. The 4 series is the coupe version of the 3 series, and therefore not above the 3. 6 series coupe of the 5. 8 series coupe of the 7

[@ianapriliatuono]

Nice one great advice

[@ian.M440]

Great vid 👍

[@thomashazell9944]

Have you noticed more road noise since fitting b8’s?

[@roadreg1820]

Not really no 😃

[@veikovrklv]

Thanks for that info :)

[@bruhbruh2290]

i have adaptive suspension, would it still be worth fitting dampers?

[@roadreg1820]

Bilstien do an adaptive version. Those would work and be much better than what you have now. Allot better!

[@chrisball3337]

As a former owner, I modded mine with the bilstein damptronics. They are costly and the car sits a little high after even on lowering springs. I'd suggest saving cash, going with non adaptive and coding out the adaptive function

[@tyronelul2687]

Currently have rear b8s with mmr springs all round. Was night and day after fitting. Would you say its worth doing the fronts too?

[@roadreg1820]

Hi Tyrone! I’d definitely recommend doing the fronts too.
