i have heard from some drag racers that turning directional wheels backwards means more grip in the straight line. the con of this would be no traction turning, but for a straight line use only would this work? im curious for the next time i go to the track. anything for free that will get me into the 12's ill take. what is your input

thats new to me but, you have to lower the tire pressure and a good burnout for a street tire to grab. Why not just buy the real sticky tires.

car weight reduction? driver? just kidding. how about a female driver. They usually weight less than the males?

If you turn your directional wheels backwards your brakes will heat up. The wheels are designed to pull air thru the wheel, if you turn them backwards they will hold the hot air in, and depending on how hard and long you are braking you will eventualy have brake fade. This is due to the brake fluid heating up so much that it almost boils.
Now, I am talking about wheels, not tires.

Ok. I *Think* he's talking about the tires, not the wheels. More traction from the wheels being on the wrong side of the car makes no sense.
This premis would certainly depend on the tire and it's tread pattern.
It's unlikely to make any big difference and you'd have to be a REALLY good drag racer to notice the improvement if there is any.
Just get some drag radials and be done with it.

Drag tires kinda develope a grain for lack of a better term after several runs. Turn them around for better traction. It was either Moss or Colleti that said it's like petting a dog against the grain of his hair.

And no burnouts on street tires. It doesn't do anything but waste rubber. Do a small dry hop to clean 'em off and go.

maybe he's talking about victoracers? they only make right tires now so they are all one direction. for the other side you flip em' so you have the same tread block on the inside or outside of the tire as the other side. also they recommend flipping the tires again to get more life out of them.

Turning directional tires backwards won't gain you traction differences. It will make you lose any wet traction ability that the tires previously had. The only reason I can see for anything like that is to prolong the life the tires due to some aggressive alignment settings.

As far as wheels, I haven't seen a directional wheel ...

Sure you have, S4 GXL wheels were directional. I think the early TII wheels were directional as well. They were to be mounted on a particular side of the vehicle.

actually it will...but the only tire ive seen it done on are nitto nt555 DR's....they make a big difference when turned backwards...alot of fwd guys do it
