ASM TechTalk: DIY SPLITTER, Track Tested & Proven With Results | ASMotorsports

In this TechTalk, we go through every step of making your own hardware store-spec splitter or undertray. It's easy to overpower the aero balance of a street car with just about any wing, making a car understeer too quickly; offset that aero balance with a relatively simple and easy-to-make splitter or undertray.

They key is finding a mounting solution that works for your chassis, then paying attention to details in air flow, like airdam and tire spats, to achieve maximum efficiency. We've run this style splitter or undertray on our track S2000s and more, leading to dozens of wins and records.
