Lifting

• Lifting is the default option for off-roaders and most dub enthusiasts. Lifts come in two basic varieties: body lifts and suspension lifts. Body lift kits utilize spacers that fit in between a vehicle's frame and the body; they're the simplest, and fairly consequence-free if you don't mind a slightly higher center of gravity. Suspension lifts utilizing longer springs and replacement suspension components will give you more off-road versatility by increasing suspension articulation. Lift blocks that fit in between a truck's springs and axles will net you a bit more clearance, but aren't as safe and may cause the springs to twist under load.
  
  

Tubbing

• "Tubbing" or "mini-tubbing" is popular among hot rodders and customizers, and involves replacing the stock wheel tubs -- or recesses -- with tubs of a larger circumference. You're still limited by the size of the exterior wheel arches, but only if the tires protrude out far enough to contact them. Tubbing involves some major cutting and welding, and not a small amount of fabrication skill, but can offer massive tire clearance without altering the vehicle's ride height or appearance. This facet makes it popular amongst customizers, who need the clearance not for larger tires but to drop the body to the ground with hydraulics or airbags.
  
  

Radiusing

• Radiusing begins where tubbing ends, and it's the go-to option for those pragmatists who're looking for massive tire clearance on the cheap. Radiusing involves cutting the fenders or quarter panels around the wheel well all the way up to the tops of the wheel tubs. Radiusing may be used in conjunction with tubbing, but may offer enough clearance on its own if the the tire naturally protrudes past the fender. Radiused wheel wells aren't for everyone; they drastically change the look of the vehicle, and not always for the better. But they will allow you to run a wider track width and lower ride height for optimal handling, and they're definitely the cool way to show your commitment to going fast for cheap,
  
  

New Panels

• If you don't want to lift the vehicle, tubs alone will make your track width too narrow and radiusing will leave your vehicle looking like a dirt-track rat trap, then new fenders and quarters are the only way to go. Aftermarket or reworked fenders come in three basic varieties: those with larger wheel openings, wider fenders with a flared opening to fit the tires completely inside, and stock fenders subtly flared for more clearance. Many companies offer fiberglass fenders for popular chassis like the Ford Bronco and Chevrolet C/K series, and you might find a wide-body kit for your car if it's fairly modern and popular. Other than that, you're stuck with paying to have a very talented body-man rework your stock sheet metal to yield the appropriate clearance without making your car look like a freshman auto-shop project.
