What I'm describing is oversteer. I go diving into the corner and the car spins around almost facing the direction I came from instead of just turning and sliding in a straight line.

Add another sway bar in the front, keep both 25mm bars.

Stiff front = add understeer

Stiffer rear = add oversteer

I have a 25mm/25mm front/rear bars on the car right now and I guess because of my oversteer I'm looking to decrease the rear bar size or go without a rear bar. Do you guys know if anyone makes/made a rear bar that had dual exhaust cutouts aside from the ipd 25mm unit?
The stock 21mm 240 turbo bar or the 23mm 79Gt rear bar have a fit and finish second to none.

IPD will sell you a 22mm rear with the dual kick up for exhaust on either/both sides. I went up to 28mm in front and down to 22mm in the rear to help make throttle-on oversteer surprises with V8 torque a bit less exciting.

And your 740 is how old? Hey, if you want to spend hundreds of dollars instead of $20 to $30 and couple hours of time, go for it.

IF everything is right with the car.....

Learn to drive the car!

Practice-practice-practice-practice

Many 'issues' with how a car handles are due to a ham-fisted driver being a savage in his car with mis-matched tires and worn out shocks.

Practice how the car responds to inputs of steering with throttle at the same place.... Under acceleration.... Under braking... Sharp steering inputs... Gentle steering inputs...

Anyone who believes he is 'Dialed in' with our old junk isn't. We just don't have enough time behind the wheel sliding around to be there.

Keep in mind that manufacturers go to considerable effort at making sure their products do not make the evening news due to pirouetting off the road.

Driver mod is always the answer.

A really good driver will go around turns faster in a poorly done car then the savage with no talent in a capable car. Getting to where you have a feel for the car... This comes from seat time while sliding around in many situations... Different surfaces... Bumps... Off-camber turns.. Turns cambered such that you can blow through the turn at seemingly impossible speeds... . Knowing how it behaves when you are hard on the brakes and add a steering input.

Practice-practice-practice-practice

Be safe about it.

Interesting topic.

No legitimate dry "track" (or 240) experience here, but once I moved my 945 from stock front/rear bars to both 25mm IPD bars, it was much more difficult to handle in 3-6" of snow. Snap oversteer is a shocking concept once you experience it for the first time in the wrong place unexpectedly. I will be going back to stock or no rear bar before the snow flies this year, for sure. Hands down, stock springs and bars handle stability in snow/ice better.

I'd imagine this is an extrapolation or exaggeration that also applies to dry track, but don't have any real evidence.

All things being equal, more front bar will help the car transition left/right, more rear bar helps the car turn in steady-state corners. Oversimplification, but accurate.
