I finaly share my idea of improving Pro level BMX tracks as they have demand for higher and constant speed with less loss of energy/momentum especialy in turns. General idea is to "plunge" lower inside part of turn and start incline and curve course's surface before turn itself. It makes turns more flowing, and less sharp at any posible path. It means - less crashes, less resistance, less unpredictable loss of tire friction. Idea also related with growing speeds, esp. at SX races, where speeds after first turn decrease nocieably and spoils all idea of fast racing.
I'd be very glad if some of track builders could try this idea on next track. Most of all these shapes could work at slightly downhill tracks as it could be easier to provide water drainage form center of turn. Otherwise there must be proper preparatory work done.
