Grassroots Motorsports 110 For example, we plan to employ some über-trick electronic suspension on the Miata, but we can always go back to basics if it doesn't pan out. Likewise, the CRX will be kept running while we develop the Miata so we can keep our driving skills fresh, do recon days at new tracks, and test new parts. Testing opportunities do not always synchronize with your development plans. Step 11: Have Development Parts as Well as Race Parts and Spares for Wear Items Iterative development relies on track time. That means you go through con- sumables and need to be prepared for that maintenance. Brakes, fuid changes and so on are all important to maintain. Save some time in the plan for that, or you'll pay a bigger price later. There will also be unexpected wear and damage that should be considered in your schedule. More time in the seat means more possibility of a missed shift, an "off " or a parts failure. Building up the spares stash early on will help reduce the impact on your schedule. Fully loaded uprights, axles, fresh calipers, engine sensors and a splitter blade are just some of the items that could save your valuable testing weekend should an issue arise. Taking that one step further, keep your fresh race engine and transmission out of the car during the development cycle, especially if you have had these profession- ally built. You'll want something making similar power levels to get good testing numbers, but when competition starts you really don't want to have to rely on a drive- train with tons of track miles being able to provide its best power and reliability. For the Miata's transmission, we've already set aside a low-mileage, six-speed Mazdaspeed Miata box while we abuse a garden-variety six-speed removed from a friend's wrecked 2000 Miata SE. Initially we're going to swap in a bone-stock Honda K24 engine, while later we'll move to a 280-horsepower version built from junkyard cores. For One Lap itself, the car will get a pro-built 300-horsepower unit. Like we said, success comes from a series of steps. FEATURE: BUILDING A WINNER
