Because off-road wheels have the biggest sidewall, they give the biggest benefit. A lesser benefit will be experienced with other wheels depending on the size of the tyre sidewall.
Keep an eye out for the traction bar increasing when upgrading to identify these parts, or use the “Notes” column in the Key Vehicle Info section of the main spreadsheet, linked here, if you see that a car has a spoiler from the “Spoiler” column but no spoiler category in game.Īny car that came before the Casino DLC that has the “Tyres Can Clip” flag in the handling data will be smoother over kerbs and bumps in the road when they have off-road wheels applied, making them much more stable.
An example of this is the spare wheel modification on the Dubsta. For more background on the difference between downforce and spoilers, see here.įor cars that don’t have a spoiler category in Los Santos Customs, it’s possible that they receive an increase in grip from other modifications. After many changes by Rockstar over the years, spoilers are now required for these cars and will still improve cornering speeds, but to a lesser extent than if they were added to a non-downforce car. The higher the car’s downforce value, the better cornering ability it has when travelling at high speed. Some high performance cars have a downforce multiplier. Spoilers also have no effect on top speed as shown here. Some cars like the T20 and Furia have active spoilers which give the increase in grip by default, however if they are broken mid-race the car will experience grip loss until fixed as shown here. All spoilers below the option at the top of the list will give the same increase in grip - larger spoilers aren’t any better than smaller spoilers in this respect. To clarify, “non-stock” means any spoiler that isn’t the top option in the spoilers category list. Not all cars in GTA have a spoiler modification, but those that do will receive an increase in grip when any non-stock spoiler option is chosen, resulting in higher cornering speeds. Those bars should not be trusted, as shown here and here. Turbo - Adding turbo increases engine power, resulting in better acceleration and top speed.Įven if the stat bars are already full in Los Santos Customs you’ll still gain a benefit from maxing out these upgrades. Higher levels reduce the delay between gear shifts. Transmission - All add an extra gear to the car. These apply to all cars that have them and should be upgraded to the maximum level possible.īrakes - Higher levels increase braking force, resulting in better stopping ability.Įngine - Higher levels increase engine power, resulting in better acceleration and top speed. This page aims to document all upgrades to cars in GTA 5 that have a tangible impact on performance and should be used by every player.
