I have no issues with my Megabusa both on the track or in the city. Some people complain of the clutch and how it is difficult to drive at slow speeds in traffic. I don't have a problem with my clutch at all because I have the SBD motorsports dry sump oiling system with the upgraded clutch slave cylinder. Many complain of stalling the engine in traffic jams with the stock clutch slave cylinder. Also, the fiberglass seats are not that forgiving, so if you want to drive more than 25 miles I suggest some sort of padding. I don't need any, but I'm in my early 30s.
