- more rear droop
- decrease front roll center
- decrease rear toe in
- decrease the front track width (the distance between 2 of the front tyres)
- decrease caster (more intial turn in but less mid corner steering)
- increase slightly the front camber angle.
- and running a softer front end.

And flatten the roll bar

TRY:- Laying down the front shocks.
- Use lighter front shock oil.
- A softer front spring.
- Softer front tires.
- RAISING the roll-center by increasing the height of the front hinge pin mounts.
- Moving the caster clips to the front of the upper arm (when using a front diff or spool).
- Use the #12 servo saver / ackerman(SP?) mount.

Any one, or combination, of these changes should definitely increase your steering.

*Note: Changes made to the rear end will result in "freeing" up the rear, which allows the car to rotate thru the corner better, but will not have enough effect on the front end.

This will lower the roll centre. If you want to raise the roll centre you have to lower the hinge pins and this will give you less steering response

Just the opposite. The higher and or the more level the camber link, the more traction you'll have.

What I say and what you say are the same thing. The more level the camber link the higher the insert and so the lower the roll centre and more traction but less stability over bumps.

I said, "and or" for reason. Depending on the vehicle - Take our RRR for example: the natural(designed) position of the rear camber link has an angle (angled upward). To increase the roll center, you would need to make the link more level (horizontal) by lowering lower the link's outer position - because the inner position only moves further inward, toward the center of the car (you can also increase traction by lengthening the link - depending on the suspension design). On a car with vertical inner camber link mounts (say a TC4, for example) you would have the ability to raise the inner link horizontally, which would also raise the roll-center and increase traction. On our Triple R's rear end, the camber link already has an angle to it. If, you make the link higher, by increasing the outer position, you'll increase the angle and lower the roll-center - thus, reducing traction. The same applies to the front end, which has a natural angle to the upper arm. If, you lower the hinge pin / mount, you will increase the angle, lower the roll-center and reduce traction. The angled link does not allow the car's weight to go to the tire, at that corner of the car, when cornering. The more horizontal OR higher AND horizontal link will allow the car's weight to shift to the wheel in a more linear fashion.

To put it simple, the direction you move the link depends on the links' natural position.

I think both of you are thinking of the same thing just stating it in different manners.

Also, I don't think you can call it increasing or decreasing roll center because the "roll center" is an actual point or points on the car, not a quatitative value .

This is my easy way to figure out roll center. The farther apart the upper and lower arms are from each other, the lower the roll center and the more traction you get at that end of the car.

Sorry cant let this go!

Your arse about face. Lowering the hinge pin at the front as you mention will RAISE the roll centre

If you make the link at the rear horizontal you will LOWER the roll centre

I will PM you the geometry that will prove this

Cheers
