Is there any control arm upgrades for a g30?
You're about to give your whole fanbase your retinal scan. I'm calling it now, in 6 months someone is gonna prop up the penultimate anti-b58 channel using AI Kern to talk about how n55 is the superior choice. As always man, keep up the good work.
LOL
Everybody wants the best handling performance for that one apex corner on the way to work 💪
lol caught me :P
Your explanation of Roll Center is probably the best I’ve ever seen on the internet
thanks man. took me a while to understand it and its importance
I've seen a lot of your videos in the past and I love your new intros now. I love the new editing and all your information is amazing. What you do for our community is God's work. No joke. Keep them vids coming.
Thank you, sir.
I used to drive 340i and now I am dirving m2comp. It does not have B58 anymore but I can't not leave the channel because of this kind of topic. What a shot with easy explain ! Thank you very much !
thanks for watching and enjoy the car
So you’ve got all the B58 upgrades and more from the factory?
Are you going to upgrade/tune the S58? Just curious that’s all.
Congrats with a fantastic car!
@@Conservator. It may disappoints you that I am not driving G87 M2 but F87 M2competition which has S55 engine and the sound is worse than B58.
I am planning tune for my engine after support mods(Obviously crankhub). Also I am not gonna be a highway worrier, so, probably target 500~600whp eventually for track. If I drive a vehicle that has S58, I would do same or even little bit more power without support mods. :)
@@1MLE1Thanks! I’m not disappointed, still a great car. 👍
Can you do a vid on front strut bars? I've heard it makes a substantial improvement in handling and how the car feels, and is quite a simple and cheap mod.
If you've already covered I'd happily watch it
For the b58 supra owners go with verkline lower control arms over SPL especially if you run an 18 square set up. There are issues with SPL LCA for the supra even with the bulletin.
This has been the best video to explain all this. Suspension is such a tricky devil for me. So much so that I've been delaying getting a coilover kit for over a year on my xDrive car just because I wana make sure I do it right and get the geometry correct. I just want a flush fitment and xDrive cars always have this terrible reverse rake look. What do you think would be the best course of action if I were to get my front end lowered without putting too much stress on the axles? Do I need to get other components like adjustable control arms to keep the geometry happy and not have too much stress on the axles?
Protect this man at all costs! He is the reason Im taking arguibily financially irresponsible decisions this year :p
Got monoball arms coming tomorrow for my f36
awesome enjoy it
Any thoughts on how to tighten the feel of the steering on the 2017 M240i? It is precise and responsive just feels loose for a sports car.
You just mentioned lca and briefly ts in the video, as you know spl have every arm in stock front and rear as well as tie rod ends is this something you could touch on here or possibly make a video discussing?
Any updates on the DAW turbo 🫣
Changing the roll center sounds good for less roll. But, how much will this effect wheel bearing life? Did you notice much less roll? If so, how many spacers you used or recommend? BTW. I appreciate your videos. Very helpful.
i used all the spacers and immediately noticed the difference. i actually reduced front camber to keep handling more neutral, because it made the car more tail happy and front end grip improved so much. it shouldn't have an effect on wheel bearing life.
VAC Monoball upper control arms are THE best upgrade right with Coilovers for these cars. I have not done tie rods yet or end links, but I would tell everyone lowering at all to get camber plates (I made the mistake of not)
I got VAC upper AND lower control arms and it was wayyyyy too agressive. Like, every bump in the road feels like a landmine agressive. Called VAC and they recommended to keep just the lower in Monoball , like @kern417 has. So I ended up with the opposite of you; just the lower per VAC recommendation.
@@pbasmadj Interesting... my mechanic explained to me that msot road noise is transmitted through the lower but most of the steering response is through the upper...
@@chriskamen2152 interesting makes you think. I have heard the M2 , M3 have the lower as monoball, and upper as rubber, so that was another reason I went with that config. But agree the upper have more role in steering response. I think ultimately both are good and improved, just in different ways. it was the combo of both that was just way too much. I have barely gotten a chance to drive it with the new setup, so will come back with review
Excellent video.
Now if you could hop on a ✈️ over the pond and calculate my roll center there’s a cup of tea in it for you 🧤
me 2
****I actually broke 3 all new suspension bolts once I upgraded to this mod. The bolts are aluminum. Is there an upgrade for the bolts?*** Also FYI, they can still seize up, you’ll need anti-seize…a lot.
Hey Kevin, speaking of suspension, a lot of G42 M240i (2022+) owners are hearing a thumping sound coming from the rear suspension. Colder weather, slower speeds, only on very minor bumps. BMW is replacing the shock absorbers but the noise is still there. Would you have any suggestions on what could be the cause? It sounds like a rubber ball moving around in a wooden box in the trunk...to imagine the noise we are all hearing
F22 has same issue
@@AmazingAsif Any fix or aftermarket replacement part?
@@TJZTechShow stiffer springs . Try ACS
Hey Kern with the SPL Control arm spacing, since you’re adding a spacer to the mounting bolt to raise your roll center, wouldn’t you also have to slightly lengthen the control arm? I feel like geometry wise, if you add a spacer to the stud to lower the control arm you’d also have to slightly lengthen it in order to compensate for the new positioning. Correct me if im wrong. (I know the spl’s are adjustable length)
no you don't. When you lower the car, the roll center goes down without changing the control arm length. This simply brings it back up without changing any other geometry. if you do make it longer then it changes the camber curve and other handling characteristics, so i kept it the same to avoid unintended changes.
I’m a little dense but I have a f30 RWD and want the m3 control arms do I only need the lower ones or should I do both lower and upper control arms
lower ones work but you want the uppers to correct the wheel position
I’m extremely excited about getting a BMW. I need help deciding which one
If it has a B58, you will be Happy.
If it doesn't have a B58, you'll wish you got one with a B58.
Hope this helps ✨
Facts
If space isn't a priority, I would buy the BMW with a Toyota badge. ;)
M240i 💯
Honesty, the supra is what put BMW on my radar. Before then, I was worried about maintenance and longevity. I figured if Toyota trusted them, then I should take a look.
I wanted the smallest B58 powered BMW I could get, so I got a gently used M240i.
Afterwards, I bought a new X6 40i with the M package for my wife.
They've both been great vehicles.
For a street car to maintain comfort and not induce nvh a urethane bushing will be firmer but not as soft as rubber and not as firm as a spherical bearing.
Great vid as always man. About to fit my Lemforder M3 control arms to my M140i. Would you recommend changing the tension struts too?
Yeah it makes a difference to align the wheels properly
@@kern417do you know how much longer F8x tension struts are compared to F3x tension struts ?
can you report back here please if not too much to ask? interested to hear first hand experience. many thanks - fellow 140 owner whose only upgrade so far is black rear subframe inserts
@@nallanw4329 will do mate. It’ll be next Thursday when they’re fitted, along with B8 struts. Got to wait until then to get my EDCs decoded first.
Also had the subframe inserts done, and currently on H&R lowering springs. Diff and ARBs will come eventually… 😅
@@jameslennard4062 no way - my dream spec is B8s with MMR springs (and probably the upgrades LCAs) haha. Bet yours’ll drive proper nice after that’s done 👍
Damn nothing for the G30 platform? That’s crazy
Good evening, I have a question, I did not anything referencing the G12, a 2016 740i. I could not find anything on their site.
Do they make anything for the G12?
not currently
@@kern417 thanks for the response, given your experience, what would you recommend?
for an upgrade? i don't know of any available for a 7 series. most people don't buy a 740i for handling so there's not really a market for these kinds of parts. i'd just enjoy the car for what it is and buy something smaller for a project if you want better handling.
Any opinion on fixing the a90 supra bump steer?
Spl makes a bump steer kit that screws into your steering rack. That and their lower control arm will reduce bumpsteer considerably
@@user-wc2bq2cx6o I'll have to check them out
Hi I have an f21 140i I watched the video but you don't mention steering weight, my main issue with the car is that the steering is uncomfortably light could this help by making it heavier?
It helps with more feel not necessarily more weight. Use sport mode for more weight
@@kern417there is more weight in the steering with F8x due to increased caster with F8x arms,
Ca 1 to 1.5 percent more caster
@@vollcare4076 Like i said we can make our steering heavier with the push of a button. i would argue most of it is electronic steering tuning along with a wider front tire.
Also their control arms don't create the same caster bias that we experience with just f8x arms. They have a wider track so all arms are longer.
@@kern417 not all F30s have adjustable weight. Only those packaged with Servotronic. VSS cars only have a single weight.
Off-centre response is the big improvement with Lemforder LCA’s, extra weight is negligible.
Boom it’s now an M3
that easy
If you install the spacer at the ball joint, technically the geometry says you need to increase its length.
if you mean the control arms, the bolt for the bearing is long enough to use the spacers.
Nothing for the g30 though 😭
I swear there’s nothing for G30s especially 2020. 😭😭😭
F30 gen1 340i has this terrible floaty feeling, like tf is that
my 2020 m240i was like that when I first got it last year. It was floaty and felt like a motorcycle following the grooves of the pavement. it's my first BMW and I was like what is this crap, I thought BMWs were supposed to have superior handling, my old 2015 Challenger handled way better on the road and in the corners.
I was almost ready to take it back to Carmax but decided to change them for the m2/3 control arms and torsion struts. those along with proper tires (had OEM run flats on it) made it feel like a new car, and convinced me to keep it... for now.
😑
