I plan on participating in some events on a road racing course. What are the advantages of having a Smooth Line Hardtop?
Most courses will require a roll bar in a convertible for any event while a hardtop is exempt. Check your local rules. For the serious competitor a Hardtop will help stiffen the chassis, aerodynamically cleanup the car for a higher top end, while quieting down the wind noise allowing for more concentration on driving, all resulting in lower lap times..
