An older guy did a ride-along with me and gave me a tip to keep you planted tight in your seat. With the seat controls right by our leg, this is easy to do.

-Turn off VDC (always a good reminder! and you won't be able to reach it after you lock your seatbelt )
-Adjust seat to your driving position and buckle seatbelt.
-move the seat back about 3-4 inches
-Pull up on the upper belt to make the lap belt tight against your body.
-Quickly jerk the upper belt downwards to make it lock
-Move the seat forward while keeping hold of the belt so it stays locked. As you move forward, the upper belt will tighten up against your body and it will stay locked there.

This helps you stay locked in your seat and you don't have to be pulling on the steering wheel when going through corners.

 

Nice! I would have never thought of that.

 

Used that this past Saturday. Doesn't do a whole lot, but better than the normal looseness...

 

I use it all the time, I think that it's a must. Keeps you firmly planted in your seat. You can also get a CG lock it basically does the same thing without having to move your seat. Eventually I'll get around to picking up a harness.
