Race cars are defined as go-fast machines, an end which may be more difficult to achieve with a narrow and tippy wheelbase hence prodding you to ask, "How can I widen my stance of my race car?" You can widen the stance on your race car pretty easily with the right parts, which may include a new set of wheels if that's the tack you choose to take. A wider wheelbase on your race car can help increase straight-line stability, braking stability and cornering prowess in one fell swoop.
To widen the stance of your race car, you will need:
- A set of high-quality wheel spacers
- New hardware to mount the wheel to the spacers
- A jack
- A lug wrench sized to your lug nuts
- Anti-seize compound
- Torque wrench
Wheel spacers move the wheel hub further away from the axle, effectively increasing the wheelbase without affecting tire width or suspension geometry. High quality wheel spacers made of alloy steel can safely relocate the tires up to two inches outboard, and take only a few minutes to install.
Park on a level spot. You don't need concrete below you to raise the car, but it helps keep your knees clean.
Raise the car. Do yourself a favor and raise one axle at a time completely off the ground. Raising all four and removing the tires is asking for serious brake rotor and chassis damage if one of the jackstands slip.
Remove the tires. Nothing fancy here; just remove the tires and set them off to the side.
Put a dab of anti-seize compound on the stud threads. This will make it easier to remove the spacers at the track if you want to change them out.
Install the wheel spacers. Slip the spacers over the studs, and secure them with the replacement lug nuts provided with your kit. Torque the nuts to about 100 foot-pounds, depending on your vehicle specifications. Tighten in a "star" pattern.
Reinstall the wheels. Apply some anti-seize to the spacer threads, and install the wheel. Tighten starting from the bottom lug nut.
Torque the wheels. Wait until the car is on the ground to set the final torque, and then double check it. A little bit of time spent double-checking your wheel torque here will save you a lot of time spent in the emergency room.
