need harder springs for my coilovers????

[Foxy-jim]

I'm talking more about the polybushes in them. I know the wishbones won't do anything but the stiffer bushes will!

But Jim, the point is they WONT make a difference!!! The polybushes wont affect the rate at which the spring compresses/rebounds, therefore wont affect how soft the spring set-up is, and therefore how much the car rolls/if it hits the bump-stops/dampers!!




Look at the picture above...


Polybushed wishbones have a stiffer rubber in effect where the wishbone mounts to the bottom of the hub, and the two points where it mounts to the car. It is mounted to the car by bolting THROUGH the rubber bushing. It is mounted to the hub by a ball-joint, which is set into a rubber bushing. Therefore, by having uprated bushes, you only restrict the movement of the hub in relation to its lateral motion, rather than the stiffness as it moves up and down, as it will be pivoting about the bolts which locate it to the chassis.

So in short, as I said, polybushed wishbones will improve the handling in terms of sharpness of turn-in, and will also last longer, but they will do NOTHING to improve the roll or pitch of the car. This can be done by changing spring rates/lengths/dampers.

Fair enough, I stand corrected!

I'm not digging I was just displaying my understanding at the time. Which was wrong. I just didn't appreciate the s**tty comment in reply!
