How good of a driver am I really? Let's call me intermediate. However, entering turn 1 at BIR at 120-125 mph and turn 2 at 100+, balance and stability are a big deal no matter how good you are - you are at steady state from a suspension standpoint for a while during those corners. Sounds like the strut brace is a must have. We don't have black or red run groups but in any case my car is silver

Flash - Are you referring to the Brey-Krause lower brace? - that is the only one I've seen, it looks well designed but is not an inexpensive upgrade.
