The Nittos are a great street and highway tire. I've found they don't stick too well to a rubber coated surfaces. I go to the track so rarely that it would be hard for me to justify shelling out $ for a set of dedicated slicks. They've closed nearly all the local tracks around here. It's over a 2 hour ride to the closest ones.
Those are some very good times for a heavy car with those gears and limited traction. Nice build.
Down here what the people with street tires do is to launch from the side where it is plain asphalt, rather than the treated area, seems to work well in that situation.
