I live in a fairly populated, busy suburban city. No places really, to practice Line Lock, Torque Reserve, Launch Control. For the most part, I would need to practice with that stuff on a Wednesday night grudge race where I can only get in about 3-4 practice runs. However, the starters are always rushing everybody up to the line to keep it moving, moving, moving. I don't have a big problem with launching off the brake. However, I'd much rather do my burn outs with the line lock. That would be a much cleaner, effective burn out without the wear and tear on the Brembos. I'm committed to practicing with the buttons for the line lock before my next trip to the track. I'm at about 10.67 and want to get down to at least 10.50 before the end of the season. That would be sweet!
