OK everytime I see an exit ramp I seem to press the gas pedal rather then the brakes.

Now it always seems everyone wants there car lower and with stiffer springs. I'm thinking maybe this isn't such a good thing after all. Well to a point. It seems I kept adjusting my ride height until before I knew it...it was almost at stock height to get the right travel for hard cornering and not letting off on rough pavement.

So right now I have ground controls 450f/550 rear with konis. The front sinks into the corner alot more then the rear. Which at first made me think the front needed to be stiffer. Now I'm thinking I got it wrong. The rear I think needs to be softer.

No matter what your settings the weight shifts to the outside in a corner. With harder springs the the body doesn't drop(or roll) as much. With softer springs the body will drop into the corner and ultimately lower the center of gravity increasing the speed you can attempt I would think.

Also would mean you wouldn't have to run much negative camber since as you drop more the camber increases.

So anyways I will try out this theory by changing out the rear springs for 450s. I think it will help in the corners but also make for a better quality ride. 550 and bumps can be a bit much. Then I will test the tires with a temp gauge and see if in fact I can decrease the negative camber a bit. Set at -1.7 right now in back.

 

There are too many false assumptions in your post. The biggest one is where you ignored the effect of body roll on the inside tires. When you unload them they can't provide much traction.

It's true that if the suspension is too stuff, pavement irregularities will upset the handling of the car. However, if it's too soft, you might as well be cornering with two tires instead of four.

Do some internet searching on the "traction circle".

Have fun!

No problem. Just saying in this instance maybe it's to stiff. I don't see how the body roll is really effecting how the weight shifts around corners. Like I said the more they body rolls down the more it is lowering the center of gravity. But in all honesty I don't think there is much weight on the inside going around corners. I can say without a doubt there is no weight on the rear inside tire since it is usualy off the ground.

Again the traction circle is great to bring up. Softer suspension would mean more roll therefore less negative camber in order to keep your traction circle on the ground. So in fact with less camber you would have your traction circle earlier into the turn. With my current -1.7 in the rear you can almost feel the rear tire tilt into and grip the ground as the weight transfers.

But yeah I ordered rear 450s to see how it will work out today. put the theory to the test

I think it is gonna make it a better all around car but I could be wrong.

 

What Size Sway bars do you have?

 

stock up front and none in back

you could soften the rear and get a stiff bar (ITR maybe) and that would give you a better ride, along with less understeer.

If you just xfer all the weight to one side (and mostly the front) there's only so much lateral force you can dish out to the outside front tire before it gives up traction. 4 wheels grip better than 2 afterall.
