S2000 Front Wind Splitter “Backyard Aero”

S2000 front view

The Honda S2000, ranked #1  in the BBC Top Gear Survey in 2004, 2005, and 2006. They said ” Again it shows that a highly-tuned car doesn’t have to be a headache to live with, even one with an engine capable of rev’s right around 8,900rpm.”  Highly tuned? But don’t we all want that? Okay then, the S2000 was rated Best track car under $10,000 by Modified Magazine in their January 2012 issue, now that’s more like it! Here at Project Import we are S2000 admirers to the say the least, and there are many steps to get the S2000 to be a well bread track machine.

IMG_4529Aside from the brakes, drivetrain, engine and suspension(tires are part of the suspension people), you have aerodynamics. Now there are plenty of well made adjustable wings out on the market for S2000’s that were made using technical data from wind tunnels tests or a fluid dynamics analysis. So that area is covered. But what about the front wind splitter? There are options out there integrated into front bumpers, but the amount of money you have to spend after one off course adventure can be very expensive. Coming up with a cost effective alternative for a front wind splitter by imploring the basic knowledge we have of high and low pressure zones we come up with “Backyard Aero”. Basically, the reason for a front wind splitter, plus air dam in our case, is too increase downforce and helping the tires to have more grip as well as reducing understeer. This is done by “splitting” the air creating an area of stagnate or tumbling air above the splitter causing the high pressure area you see above. The air directed under the splitter is then moving faster which causes the low pressure area. In turn high pressure is drawn to low pressure areas, Bernoulli’s principle (thanks Wikipedia).

Mocking up the s2000 front splitter

So now that we get the idea we start construction. The main component we use is a sheet of alumalite, alumalite is a strong, aluminum composite panel with a high-density corrugated polyallomer plastic. Its light weight and strong but won’t rip your whole front end off if you snag it.

Outlining the splitter shape

Next now that we have it place in front of the front wheels we mark it out, 5″ around the bumper (being that most rules unless competing in an unlimited category say that the splitter can not protrude more than 5″ past the bumper).

5″, as you can see we incorporate the stock fender plastics and match the splitter to it.

After we mark it we CUT!!!!

Always have to make sure it fits.

Choice of good mounting points is important, because depending on what track you are going to you may be hitting 150mph and don’t want that thing coming off.

“PI splitter support rods” are important, keep the point of highest strain in check. We always tie them into the bumper beam or make a solid support. Our test is always to hang on them. Our front air dam is made of aluminum tightly attached not to allow air to pass between the bumper and the splitter.

In the end you can see that the splitter goes back to the front subframe. You should always make sure that you allow some air to flow into the fender wells, or duct to the brakes. In this S2000’s case

In the end a well rounded front splitter. We have also attached pictures of other S2000 aero we have had the privilege of taking pictures of. For different designs and more ideas check out http://www.mulsannescorner.com/     Driver Kevin Courtney’s personal design, he incorporated APR front canards, front air dam is made of thick plastic. Incorporated brake ducting into his vehicle.

His rear diffuser is also made from alumalite and thick plastic.

Cars and Coffee Irvine December 13, 2011

If you live in So Cal you have the opportunity to see beautiful cars as you drive down PCH. But every Saturday if you are willing to skip the morning cartoons you can see them up close and personal. Starting at 6am in Irvine, at the Mazda North American Operations building we are privileged to have Cars and Coffee. You are able to view European exotics, classics, some beautiful American muscle, and in our case some well rounded Japanese track cars. We brought out one the track ready S2000’s we had just finished fabricating a front wind splitter on. So you can imagine driving on the 5 freeway at 6am with no windows and no heater. Praise the Lord for beanies and thermal underwear. It was a smaller show out this day, only around 200 cars. Normally the place is completely packed, every parking space taken. None the less it was a fun time after we got the Starbucks coffee in us.

Special thanks to our sponsors Eibach Springs, Church Automotive Testing, A’PEXi, Sparco, WHITELINE, Spec Clutch and Motul Competition Clutch.
