I dont really know. There is an HKS inter-cooler system and it's currently getting new shock absorbers, a full set of brake disks and pads and new steering rod. the gauges are for oil pressure and boost pressure but were not re-connected after the crash but i'm gonna try and do that (may need new sensors). there is also an amazing raptor exhaust system that really opens up the noise. I also need to get some foglights.
