VRC PRO - .VRC and .VRH

[squidiskool]

I'm trying to extract (...or convert?) the data for the files in VRC Pro. I don't even know if it's a model, or an archive. It's unknown what engine this game runs on. Is this a ripping project that's gonna be iRacing levels of impossibility? I hope not. The game has such a small community though, and it's the only RC game with detailed models.
Samples:
VRC file (Unknown chassis file? Probably a buggy chassis.): 8_bu_1 (mediafire.com)
VRH file (Unknown chassis file? Probably a buggy chassis.): 8_bu_1 (mediafire.com)
They both have the same MAGIC of VRC. I think it's an archive because there's data.vrc in the game's main directory. I've tried the VRC quickbms (surprisingly there is one) but I think it's actually meant for Virtual RC Racing, a game that predates VRC Pro.
I've also posted the problem on XeNTaX and ZenHAX, in which nobody has responded to (excluding me).
