How to Race a 4-Speed Car

Newb here when comes to racing as well. NOT that I'll be doing much of it. Mostly for fun. Could someone explain what "take the slack out of the driveline by releasing the clutch just prior to the point of forward motion" means.

Just that. With the brake engaged, let the clutch out almost to the point of foward motion of the vehicle. It helps to tighten that little bit of movement in the driveshaft just before you drop the clutch. I had 92,000 miles on a set of stock U-Joints in my 5 Speed Dakota, launching on a 150 shot and slicks. Never dropped a driveshaft. And that was almost every weekend for about 3 years.
