Hey Greg, you can always get a soft top! They are fun to drive. I just wouldn't track it.
If I recall correctly the 289 cars CSX2000 had better F/R weight distribution(51/49 but don't quote that). I believe what made them ill handling was the power and the antiquated suspension design. The 427 cars CSX3000 had SLA suspension design which was better but not great with that heavy 427 side oiler in it. Bob Bondurant, Phil Hill, and Dan Gurney all raced the 289 cars. Daytona coupes were based off the 289 chassis. The 289 FIA cars are my favorite.
