I tried John Prices LRP 5.5 in his D4 yesterday at Bury and it was too quick, way too much for what was needed with too much power and top end and near uncontrolable.
Both my self and john agreed a slower motor was needed, I would say after using Johns system a 6.5 in both cars is more than enough, possibly a 5.5 for tracks with a big straight. But for technical tracks such as Bury metro, a 6.5 would of been dialed.
