Using this ACT Prolite flywheel is great for your racing needs. First, make sure your vehicle is the right model - 2004 - 2021 Subaru STI or 2007 - 2009 Legacy GT Spec B with 240mm, 6 - speed applications. When installing, follow the standard procedures for flywheel installation. Since it's designed for racing, expect a bit of gear rattle, but that's normal and comes with the improved engine response and acceleration. For maintenance, you're in luck! This flywheel is serviceable. If it needs resurfacing, you don't have to buy additional parts. Just take it to a professional mechanic. Also, keep an eye on the high - RPM performance. Thanks to its forging, CNC machining, and dynamic computer balancing, it should run smoothly at high speeds, but regular checks are always a good idea. Remember, this flywheel is best for race use, so if you're mainly using your car on the street, you might notice a slight reduction in drivability.
