Some autocrossers take off the front on the RSXs. The pros an cons:

Pros:
1) More traction up front. Since understeer = front losing traction first, it counteracts dastardly understeer

Cons:
1) Too much body roll can distribute too much weight to one side, to a point where the tires can't handle the extra work. Not sure if that'd happen with your car
2) Steering responsiveness will be reduced. You'll probably need to have a slightly earlier apex to compensate.
3) Increased transitional oversteer can make your car less stable in hard turns, possibly making your car prone to spinning out (kinda doubt this would happen just from taking off the front sway though)

As an alternative, you could also get the Si rear sways and counteract the understeer too. The stiffer you go though the more you car can get antsy in hard turns, but Si rears are a modest upgrade. Also, sways that are too big can cause you inside wheel to lift in hard cornering.

if the spring rate was increased in the front could that improve responsiveness ? after removing sway bar

To a point. The higher spring rate you use, when you hit a bump (even a small one) the spring compresses less and uncompresses faster which can launch the car, tire included, off the ground. This is called suspension frequency. A tire that isn't touching the ground, isn't increasing traction.

Although the frequency is faster, the uncompressing is dictated more by the rebound dampening, afaik. The launching happens when the spring doesn't compress enough and launches into the air instead. It also happens with excessive rebound dampening on consecutive bumps, where the uncompressing resistance is so high that it just jumps on the next bump.

i noticed a lot of japan tuner cars are like that the first that comes to mind is the mines skyline i seen a vid of Keiichi Tsuchiya driving it and the car seemed really bouncy or jumpy over every little bump on the track or is that something different ?
