I'll try to simplify what should be the order of things for the TBO class. The RB4 should be approximately 0.5 second faster per minute on average than the FXO. It should dominate the rallycross to accurately depict 4WD superiority for rally events.
The XRT should be approximately 0.3-0.4 second faster per lap than RB4 on average, with slightly graeter advantage for the higher speed tracks to accurately show the suitability of RWD for high speed circuits. Its lower weight and lesser drivetrain losses should be displayed with its dominance of high speed tracks. However, for shorter and more technical circuits, the RB4 should have a slight edge (0.2-0.3 seconds faster as a rough guide). This showcases the differing advantages and disadvantages of both layouts.
The FXO is already unusually devoid of typical FWD problems such as excessive front tire wear, so its not too disfranchised. The relative ease to drive it consistantly fast should make up for its slightly slower ultimate performance, especially for endurance races.
Please post some valid comments and opinions about this. I thank anyone who posts a serious and reasonable opinion on this.

Being an excellent sim that LFS strives to be, realism should always be the first priority, so cars of the same class but radically different drivetrains should NEVER be too equal. Its LFS, not NASCAR after all. The same arguments I lend to the turbo road cars apply here. To be realistically fair, XRT shuld have a SLIGHT overall edge on tarmac whilst the FF should have the edge on mixed surfaces (Rallycross) to show the stability benefits of FWD.
). The XR will be the slightly more difficult choice, but the reward will be ultimate speed. If races grow long, the FWD XF has its consistancy and ease of driving trump card as well(it just takes less concentration to drive and is a bit more forgiving). So overall, both have a hope to win.
So much for 4WD advantages. Well, there's always the next patch.
