Running Xray t2 009 indoor and having major oversteer problems going through chicanes. The car handles great everywhere else but I get to the chicane and it's so loose I have to slow down and crawl through. Settings : - Downstops : 6 Front , 5 Rear 1.5 Camber all around 0.5 degree toe front 2 degree toe rear 1.6 roll bar front , 1.4 rear 6mm ride height all around I'm not so sure on the track width, on the front there are small shims used but on the rear no shims used. Could this be the problem ? |

Try a bit more rear toe first... 2 degrees!!! Step up too 2.5 then if better but still not amazing 3 degrees J |

If the car is great everywhere, may you turn more that you really need. Also you can try 3º rear toe as they say, car more estable, little less rear traction. |

Widen your front track width. Try a softer front anti-roll bar for less turn-in. Decrease your ride height. |

Hello robabela. Try a harder rear anti roll bars, for get less rear grip. This is very good in harpains corners. Check your maximum radio of steering 25º. |

You calculate your FDR by spur/pinon * 1.9 (internal gear ratio of T3-T4). Increase your rear uptravel (downstop) to 4. This will allow more weight to be transferred to the front wheels under braking, which makes the car turn in better particularly in hairpin corners. |

XRAY and a lot of people in RC refer to it as droop and lot of other people refer to it as uplift. It is affected by ride height and by your downstop screws |
