Widebody and aero is where a car stops being modified and starts being a statement, but there's real engineering hiding under the aggression. Fitting over-fenders is bodywork; making a splitter, wing and diffuser actually work together is aerodynamics. RoughEdge does both, fitting kits so the panel gaps are tight and the lines flow, and setting up aero so it earns its keep at speed. Whether you want pure presence or genuine downforce, we build it to fit right and function, not just bolt on and hope.
Over-Fenders Fitted, Not Just Bolted On
A widebody kit is only as good as the fitment. We take the time to trim, mount and align over-fenders so the arch flows into the body, the gaps are consistent, and your wheels sit correctly filling the guard. That often means test-fitting with your actual wheel and tyre package so the whole thing works as one. Rushed widebody jobs give the look a bad name with wavy panels and rubbing tyres. Ours are set up properly, prepped for paint, and matched to your fitment so the car sits like the kit was made for it. Then it's ready for colour whenever you are.
Splitters, Wings And Diffusers That Work
Aero parts move air, and moving air makes downforce, but only if the pieces are the right size and mounted at the right angle. A splitter manages the air going under the car, a diffuser controls how it leaves, and a wing works the air over the top. We fit and set these so they complement each other and suit your speeds, mounting splitters with proper support and wings on solid stays that won't flex or crack. Get the balance right front to rear and the car stays planted and predictable as the speed climbs, instead of loading up one end and getting nervous.
Downforce Balanced For Your Build
Downforce is worth nothing if it's all at one end of the car. Too much front and you get snap oversteer; too much rear and the nose goes light and vague. We think about the whole car, balancing front and rear aero so it works with your suspension and alignment rather than against it. For a street build we'll keep it usable and clean; for a track weapon we'll chase real, balanced grip you can lean on through fast corners. Either way the aim is a car that feels more stable and confident the faster it goes, not one that just looks the part standing still.
Finished And Fitted To Last
Aggressive aero takes a beating from road debris, driveways and the odd track kerb, so how it's mounted matters as much as how it looks. We fit brackets and hardware that hold up, reinforce mounting points where the panel needs it, and prep every piece properly for paint so the finish matches the rest of the car. Splitters get support that won't fold on the first speed bump, and wings sit on stays that stay put. Done this way, your widebody and aero package survives being used instead of cracking and sagging after a season, and it keeps looking sharp long after the build is finished.
