Are you talking about straight-line only? I know for damn sure if I'm gassing it around a corner that's what I'm in for. I don't understand why you disregard the tires immediately; think about what is making contact between your car and the road.

So I suppose the best answer I have is leave the ASR on then if you have it - but that will only limit it some.

4.10s and street tires, hmmm?

This seems to want a "driver mod", know your (tires')
limits and work the edge. If you want the hardware to
keep you out of trouble, you picked the wrong platform
(too many cylinders, for starts).

Learn how to drive is your best bet. Trade car for a honda would be the next thing you should do if you cant figure how to not spin the tires.

I went from having good street tires to having chepo tires and I've had to relearn the limits of the car all over again. I miss my old GS-D3's .

There isn't any. Fishtailing is an inherent characteristic of a rear wheel drive sports car. Any car with considerable power without the traction capabilities to match it will fishtail when being given full power. Even full power dragsters with the uber slicks still slip at the line when they launch.

Best bet is to learn how to feather the accelerator pedal and learn at what point that traction is lost. There is no quick fix "mod" to help this one. Learn to drive, or, like others have said, buy a Honda.

The right side lifts due to the driveshaft torque
reaction, so the left tire will produce more force
and this makes the thrust vector off center. If
the front tires are resisting it then the rear will
scoot left.

Spinning tires have way less friction force than
stuck ones and no directional preference left/
right. So you can slide the rear against the
inertia of the body, the resistance of the front
tires, etc.

Sounds like you're not worried about it, just curious.

You can also have the 4 wheel alignment of your car checked; they will be able to see if your thrust angle is off. This is uncommon, but if it's off it will exaggerate movement of the rear under high torque. Worse yet, this happens when you hook well with both tires... so you end up pointed (and moving) in an off-center direction. If the car's ever been in an accident, thrust angle alignment should be checked.

Also a good reason to buy adjustable LCAs, so you can dial in the thrust angle

i dont think the car has had alignment in a few years.

thats on the to do list along with the ball joints and front A arm bushings.

is there a write up on how to measure thrust angle?

This is what I figured made the rear end kick out to the side even if you are launching straight. The more power you have, the more twist occurs. Say your wheels were not going to move, what would move instead? Your rear axle would, like a helicopter ( assuming it wasn't attached to anything and nothing was in the way )

Does that make any sense? This slight reaction to the driveshaft causes a downforce on one tire and an upward force on the other.
