The Beginners Guide to Aero Modifications for your Car

Today we cover off all the basics of aero modifications, from road use through to autocross, track and straight line racing. We're just covering the basics, but after this video you should have a decent idea of a development path for your car in the way you want to go.

This video was requested by one of my patreon supporters! Support me through the link below:

The first thing you do should be put a huge spoiler on your honda civic

[harrisonsiegel]

Each vtec sticker you have adds 2000 lbs of downforce

[gamingmadesimple]

Note1. Big wing to make my civic turn harder

Note2. Vent exhaust straight up through hood to provide down force without drag when I'm pushing my civic to 100+ kmph

Gotcha I'm ready for the drag strip

You should do more on high speed aero designs, not many people talk about it, but in my opinion it is hard to get low drag and enough downforce to get stable around corners at very high speeds (200 kph minimum and upwards of 350 kph)

I bet you would be surprised at how many of us real racing engineers watch and learn from your vids!!! Thanks😂🏁

0:50 another instance for street use is the Mazda MX5, at motorway speeds of 120-150kph the car is effected a lot by crosswinds from trucks and environment. There are many front splitters on the market which have been known to increase stability considerably.

Having fit one on my own I can vouch for the fact that the wheel feels much more stable and the car becomes much more planted at high speed.

I'm proud of you!! I asked for drag stuff and you put the actual car I work on in the video. "YOU CAN NEVER HAVE TOO MUCH HORSE POWER OR AMMUNITION!! Bill Miller is king

i'd love to see more videos like this, but have them slowly step up in complexity and in-depthness. So for example you could begin to get more into individual parts and how the different shapes and designs have different effects. I know that you have done similar videos already, but if these ones were a bit more DIY focused as this video somewhat is, i think that would be pretty neat. Anyways love the videos! Keep it up! Cheers mate.

I don't know what I'm doing here I don't even own a car

[DasParedes]

the amount of info concentrated in this video is incredible, I feel like I saw 6 videos about aero in 1/10 of the time, congrats!

[mlcollingwood]

That is a very old photo of my MX5, it was also the first time I met the maker of this video! Thanks Kyle!

I added a high rise spoiler to my Honda Prelude just for looks. Although I got a spoiler I knew was functional on the car it was designed for, I didn't expect it to do much other than add some stability to the rear of the car at high speeds. I was pretty surprised when my rear tires stopped squealing while taking certain turns that I would frequently drive in the valley. It seems that the spoiler I have on the car actually helped at speeds as low as about 50mph. Regardless, I only really put it on for looks and will be going to a chassis mount spoiler once the car is closer to being ready for the track.

Hello Kyle, I was wondering if you could do a short video on blown diffusers?

[SilverScarletSpider]

Do you think that bolting a box fan onto the rear of a Honda Civic would noticeably increase aero performance?

[kevingram]

This was the best YouTube video I have seen in a very very long time

[LPdeLP]

3:23 that is one Biggass wing.
It probably could drive upside down at like 26 mph

[xWORLDxCHAMPIONx]

Oval sprint racing is an incredible example of complex huge aero working beautifully!

[LogieTK]

Yeet bout to wak a big mcwing on my hyundai getz

I kind of chuckled that you mentioned dragsters at the end... They really play by their own rules. A single top fuel dragster makes more power than the first 5 ROWS of the Indy 500! They accelerate faster from 200mph to 300mph than most race cars can accelerate from 0 to 100mph. At the starting line, the clutch is intentionally slipped to allow traction. This slippage burns off over 1000hp AT THE STARTING LINE. The engine isn't even at full throttle at that point, and certainly nowhere near peak power rpm.

Dragster aero doesn't follow the rules of anyone else. If you told a crew chief that you could give him an extra 300hp worth of traction at the starting line, but that it would cost him 3000hp of drag at the top of the track, he'd take it in a heartbeat.

Awesome, gives me encouragement to go sick on the khanacross car!
