It's a very abrasive surface, so expect a LOT of tire wear. It's not real tough on brakes. In a 5-speed NSX, you can do the entire track except for the straight in 3rd gear, and get up to 4th on the straight. So basically 2 shifts per lap. Its a great track for low power mementum cars like Miatas. Plenty o' run-off room, so it's very novice friendly.
There is no tunnel under the track, so you have to wait for them to shut the track down to cross it and leave the premesis, which they try to do hourly in a Chin event.
