I thought it would be hard to set consistent laps on Grand Canyon but it seems the larger track is, the more room you have for adjusting your pace. It will be interesting to see how the others did here. The current tuning rules simulate low-budget rallying where independet teams would show up with some really wicked combinations. Stock or tuned, both is good as long as restrictions aren't being compromised. The system is set to cover every aspect of rallying in GT4 through few rounds, by gradully increasing abilities of eligible vehicles and offering different courses each time.
