Making A Custom Front Splitter For My Myvi G3

In this video, I try my best to explain the purpose of a front splitter and what are the issues I wish to resolve by having it installed to my car.
My suspension setup was far from perfect and there is only so much tweaking that can be done before I hit a wall and have to look out to other options. After a long time of researching and drafting it, I have decided to get myself a custom front splitter to settle some issues I was facing.
Please note that this design is based on my personal driving style and car setup. It does NOT guarantee an increase in performance to your Perodua Myvi G3 (or any other car). Messing around with you aero CAN disrupt your airflow and make it worse if not done correctly or thoughtfully. Kindly do a lot of study, testing or consult a professional.
Disclaimer: I apologize if I got some facts wrong, I genuinely tried my best to deliver this content as informative and as entertaining as possible. I am still fairly new to this and will try my best to educate myself and grow as a driving enthusiast.
Stay tuned for the next episode where I test out the new aero before my track day!

Content best hariz. We need more! 💯

[@MeorHariz]

Thank you so much Pie! More to come, definitely!! 😆✨

[@SyafiqAyob]

Very informative vlog bro, didn't know that small mods like front splitter can give huge improvement on handling 😮 Besides, your "Spirit" looks more aggresive now tho! 👌🔥

[@MeorHariz]

Thanks man! I aim to make more educative content such as this that are science and data driven. It helped my handling tremendously but I really would like to highlight that messing with the aero is more of a way to fine tune the handling rather than thinking of it as a way to upgrade a car's performance. This splitter that I made was effective for my suspension setup but it brought in a little bit too much downforce that my front suspension bottoms out during hard cornering. If someone were to use a splitter as big as mine, they'd need a suspension setup as firm as mine or even stiffer!

[@mg3hub]

Nice information dan satu ilmu yang baru. Baru tau kedai yang boleh buat betul2 aerodynamic function. Video pun makin improve. Keep it up 👍🏻

[@MeorHariz]

Yup, Flow SI Aerodynamics memang terkenal dengan kaki track dan touge. Dari MSF, drag racing dan drift cars - semua dia pernah buat! Still nervous and blank sikit kalau cakap depan camera, will try to improve diri hehe. 🙆‍♂️✨ Thank you Raziq!

[@Apos19]

custom mod that actually serves it's function and compliment owners driving style. that's badass man. haha

[@MeorHariz]

Thanks a bunch man! I really prefer not to have non-functional mods that will just add unnecessary weight or drag to the car. Took me a long time of studying and drafting it out but so glad it worked. Just released a video of me testing it out on track too!

[@awokdew]

Nice splitter depan 👍 nampak lebih agresif

[@MeorHariz]

Thank you Awok. Ada la juga update dari segi rupa kan hahah. Yang penting dapat function seperti yang diinginkan 😋

[@MeorHariz]

Alhamdulillah, thank you! InsyaAllah if you do well in your studies and get a well-paying job, you can own your own Myvi or something even better too! Don’t stop chasing your dreams and once you’ve reached it, create a bigger dream to continue the chase! 🤲✨

[@WayzerDude]

That transition to the intro montage is just *chefs kiss* -on point! Never knew that such a simple addition to the front bumper in the form of what is essentially a carved piece of aluminium can do wonders for downforce/aero improvement. Out of curiosity, have you experienced any scraping yet? That slight extension must've made you more conscious of your front splitter I believe XD

[@MeorHariz]

Big thanks to Irfan Najz for shooting that first clip and showing me around Putrajaya to get that slick and interesting shot as well. Also, shout out to him too for the second last frame of this video where the all-new Spirit rest idly by a lake, amazing cinematic. As for the aero improvement, I'd say there are pros and cons to it. What I gain somewhere also led me to lose some of the old handling characteristics. Also, to run a splitter as big as mine you will DEFINITELY need a stiffer suspension than what I have (and I consider mine as relatively stiff already). This will be highlighted in the next video but the front splitter caused my front suspension to bottom out plenty of times throughout hard turns. Had to tweak my suspension to make it work. And yes, I've scraped the bottom a few times and there's barely any scratch marks (Aluminium Composite panels are that good). Had the front edge touch the road a few times when I descend a particular ramp but I had the edge protected with a rubber seal that I remove every time I destroy them (it's like RM3 for 5 meter).

Sorry if I was rambling through my sentences. Still not used to this whole vlogging / recording videos in public thing. When I shot this video, my knowledge was less than what I know of aerodynamics now. Hit that thumbs up button if you want to see a touge and track reaction of my new aero + Yokohama AD09 tires!

[@MeorHariz]

@@WayzerDude Thanks for the support man. Hopefully I'm able to vlog like you do someday. Very casual and effortlessly hahaha. Until then, do expect more awkward speeches by me HAHAHA 😂

[@adibz959]

That's very interesting. What if you make the front splitter to cover your whole engine area at the bottom, instead only at the front. It may improve the downforce even more.

[@MeorHariz]

This is a very good design that I would've gone for but it will be a hassle to service the car and it will also take more time as I will need to do a custom bracket to attach the splitter to the chassis. Ideally, I would want a flat floor all the way to the rear but this is still a daily driven car hahah. Maybe for my next project car perhaps! Also, unfortunately chassis mounting the splitter (of any size) for the Myvi G3 is almost impossible due to the lack of real estate within our engine bay, bumper and chassis. What I did to mine was as much as I can go for without leaving the car for days or a week. Hopefully this video was useful in some way!

[@adibz959]

@@MeorHariz I do agree. Servicing would be hard for the mechanic. Maybe this is the best setup for the dailys. Im sorry but can I have a request? I've heard a lot about lightweight pulley for myvi Gen 3. Can you try that product on your car? If not, its totally fine. I've heard it can improve responsiveness, gas mileage and add little bit of horsepower, but Im afraid to install it on my car

[@MeorHariz]

@@adibz959 That's a really interesting mod and I've heard mixed reviews on that which has led me to be a bit cautious in whether I want to install it or not. Perhaps if there is a shop that is interested in sponsoring me the part, install and provide a warranty for it - I might just do it!

[@christophercmlee]

Hi Hariz, wondering instead of Orsen shield vs splitter which one will give a better performance? Seems like both are the similar if that's the case. Please advise 🙏🙏🙏 thanks

[@MeorHariz]

Good question! Both of them are different in terms of purpose and how they work. A front splitter performs in a way where they increase the downforce on the front end. The Orsen undertray performs in a way where it smoothens out the undercarriage of a car - making a smooth air flow (no air bouncing around / get trapped by the bends and gaps under our car). For a proper front splitter, you’ll need a suspension that is stiff enough to match it before it performs the way it’s meant to be (I highlighted this in the video after this if you’d like to check that out). Otherwise, people may risk bottoming out their suspension at high speed or even worse - unpredictable steering as the suspension struggles to keep up with the amount of weight being presented to the front. The undertray smoothens out under the car, flowing air faster and lowering the pressure underneath the car. Some downforce will occur as high pressure from above the car will try to head downwards but this is very minimal. They also protect your engine components. I don’t have the undertray shield installed btw (maybe if they’d sponsor me I’d give it a try).

​@@christophercmlee Thank you so much! More track day content coming soon (specifically after this upcoming weekend).

[@christophercmlee]

@@MeorHariz just to be clear is that any particular information need to let Achik know to do something similar like your on the splitter with my toyota vios 2021 to have better speed n cornering like yours? 😅🙏🙏🙏 Please advise

[@MeorHariz]

@@christophercmlee Achik prefers you to come with a good idea of what you want in mind. He can recommend some but you should know better on what you ultimately want in-terms of design and size. I usually sketch things out with measurements ready. If you wish to have a splitter that's functional, it should be at least 1.5" and above before it start to do something. Anything more than 3" will require a splitter rod to hold it so it does not wobble or bend on itself upon impact. If you wish to have a splitter like mine, I highly suggest to make sure you have adjustable suspension with stiff enough absorbers to withstand the strong downforce - otherwise you might risk fighting for the car's control during turns as your suspension bottoms out. But if it's for daily driving and you don't go over 140km/h as much.. any size should be fine.

[@kennylee2860]

How much does it cost ?

[@MeorHariz]

It's been a while but it was in between RM300 to RM400 I believe.

[@nithyananthanpannir5914]

pakai adjustable or sport spring boss

[@MeorHariz]

F Tuned Racing, GT Series adjustable coilovers. Better to finalize the suspension setup before you touch anything aero related because you can always fine tune your suspension but the aero designs should be based on your car's general characteristics.

[@dikiddikid9587]

abang ni racer ke?

[@MeorHariz]

Saya pun tak tahu macam mana nak jawab ni. 20 tahun experience dalam go kart racing level grassroot dan a few years dalam time attack driving. Door-to-door racing pakai kereta masih belum lagi, tunggu ada sponsor atau team yang mencari driver. ☺️

[@farhanhani2271]

Hrga dia kira mcm mna? Nk buat untuk almera turbo

[@MeorHariz]

Harga dia kira ikut the amount of material used. Design semua boleh custom sendiri macam mana nak buat rupa dia. Nak tambah winglet ke, nak buat ada tajam ke, tambah rod ke apa semua boleh. Boleh WhatsApp Achik (nombor di dalam video atau description), hantar gambar contoh dan minta quotation. Jangan lupa cakap jumpa kedai dia dari video ni tau! Nak buat demi rupa tak perlu besar sangat, 1" atau 1.5" boleh lagi. Tapi kalau nak buat untuk performance & handling, better untuk setup suspension betul-betul dahulu. Suspension saya agak firm sebab memang khas untuk main track dan touge. Itu pun still bottom-out (dia compress sampai habis) during high-speed cornering sebab downforce pada splitter yang saya design ni tinggi sangat. Saya terpaksa keraskan lagi suspension depan saya supaya dia tak fully compress during cornering.

[@norazrulll1435]

Boleh kongsi kat mana setup adjustable yg betul² sedap dan berapa harga kos untuk handling yang mantap tak hariz,sy dah buat@servis 2 kedai berbeza,tapi lepas 3 bulan dah macam naik sampan..sy guna bc v1 tapi macam pakai s.spring murah je rasa..

[@MeorHariz]

@@norazrulll1435 Hi, first thing first saya pakai F Tuned Racing Suspension, GT Series. Installed di HQ mereka tapi ride height dan soft hard adjustments semua buat sendiri di rumah sahaja. Makan masa sedikit tapi selepas berbulan afau bertahun baru dapat the perfect comfort and handling yang saya cari. Saya tak pasti BC Racing V1 belakang dia pakai spring dan dampers asing (seperti torsion beam biasa) atau di jadikan coilovers (Chapman strut). Kalau asing lebih bagus dari digabungkan sebab kereta Myvi ni memang di design untuk menggunakan spring dan absorbers asing di sebabkan torsion beam di belakang. Tapi kalau dah pernah bocor, agak susah nak dapat handling yang baik. Wajib service all 4 sides to get a balanced feel. Otherwise, saya suggest beli baru je (sama ada brand sama atau lain).

[@norazrulll1435]

@@MeorHariz sy beli baru dan lepas 5 bulan pakai kiri kanan depan adjustable jem, hantar clim kedai taknak ganti 1:1 last dia antar servis,lepas pakai 3 bulan jem lagi sy terus hantar servis kedai lain sebab dah kena tipu walaupun masih dalam warranty, tapi lepas servis 3 bulan dah tak sedap juga.sy punya belakang spring asing tapi tak reti nak setup ukuran tinggi rendah absorber dengan spring tu n now langgar bum terus terentak keras, bodyroll pun sgt teruk.

[@MeorHariz]

@@norazrulll1435 5 bulan tapi dah rosak tu teruk sangat tu. Memang sepatutnya kena di ganti baru. Nampaknya kedai yang awak beli tu memang teruk sangat dari segi service dan juga etika sebagai penjual. Kalau selepas service pun tak sedap, kemungkinan besar product yang awak dapat tu memang faulty atau pun selepas di buka dia tak seal balik properly. Dari habiskan duit nak repair lagi saya sarankan beli baru sahaja sebab kalau service suspension tu lagi sekali pun mungkin akan jadi benda sama dalam masa beberapa bulan. Lagi pun, setahu saya BC Racing official tak ada mengeluarkan model untuk Perodua Myvi. Warna set suspension yang original pun berbeza dengan yang di jual di market Malaysia.
