Sway input needed?

[BMW_TUNER]

I am currently running a vert front bar and IX rear bar with m3 links up front. My new springs are phenomenal 550 front 950 rear but the rear springs easily overpower the rear bar. What sways would work best for this setup for auto-x and aggressive street use? Any input appreciated. Also I have a ton of tire on the car 255 if that matters to determine which bar is best.

What do you mean by rear springs overpower the rear bar? Typically when people get higher up in the rear spring rates like say above 750 they say the car gets tail happy or can't put down power on corner exit. Disconnecting the rear sway bar is what a lot of people seem to do to remedy that problem.

First off I would go with a less agressive rear spring (something short [2.25"ID springs are plentiful in useful rear spring rates]).

Then a mild rear bar and a big front bar.

Agreed on above. I notice a lot of people just disconnect to rear sway bar or 650-750 rear spring seems to be the norm

The rear spring rate is perfect to stop the heavy rear squat with the big rear tires and s50. What I am noticing is my front bar is strong and controls roll but my rear bar can not handle when the weight transfers from left to right in corners. In hard cornering I can feel the inside tire tucking and the outside tire dropping. I have disconnected the bar and I can feel very little difference. I would like to limit the rear roll more significantly. The front is so strong that when I jack the car up the tire comes off the ground almost instantly due to the bar not allowing much travel. I think my front is stiff and the rear is just to soft.
