Ford GT Setup Guide

From the release notes :

– The Ford GT is a tough car to get the handling balance right on. This is really based on the fact that it is a flat bottomed car, that’s forced to run a high ride hight. 55mm is the minimum ride height per the ACO Rulebook. Now with the front and rear at minimum, you’d lose a lot of front downforce, so you really want to have the car running close to 10mm of rake as a starting point with all setups. One thing to remember when driving and setting up this car is that to get front downforce (DF), you REALLY need to close up the distance between the splitter and the ground. With a min ride height of 55, the only way to do this is to get weight transfer from braking, whether it’s from lifting off the gas, or actively applying the brakes. Both will cause a downforce shift towards the front! HOWEVER, bottoming the splitter WILL cause the front DF to spike and then rebound will and cause all kinds of handling issues. Try to set the car up so that the splitter comes close to the ground, but doesn’t actually HIT the ground under braking. We have found a front bumpstop gap of 13-19mm works fairly well, though running stiffer springs, you may not need them that close.

– This is an AERO car first and foremost, so the low speed handling may be compromised by the choice of springs that will hold it up at high speed and high downforce settings! Depending on the nature of the circuit, you may want the car to trim itself out at high speed, so you’d run stiffer front springs, and softer rears. But if it’s a high downforce circuit, you may want to reverse that balance so you can get the nose down on the ground in the braking zones, to help move the aero balance forward so the car turns-in well. Using damper rebound to help hold the nose down may work, but can reduce suspension compiance. It’s a tough car to make work well, and will reward a patient driver with good speed and decent handling. Those that expect it to turn well without altering the aero balance may find it to drive like a truck!
