By lowering the forward link(swing arm)to its lowest hole in the bracket, will this increase forward bite and side bite and cause the car to roll over more? Also,will increasing the downward angle of the rear link increase roll steer? Thanks, for the help, I've believe I've this somewhere on this forum. We need the car to have more rr forward bite.

Moving the lower link up at the frame mount creates more forward bite and rear steer.Leaving the rear link alone.Moving the rear link down also will increase forward bite but will not increase rear steer as much as just raising the forward link if the front link is shorter than the rear.If both links are the same length (and the mounts on the birdcage are the same distance from the rear end tube centerline) there is no rear steer if the links are at the same angles or parallel to each other. The shorter link is always more reactive. It's all about thrust.
Thrust me.

Thanks Dman, I wonder if you lowered the front link and increased the downward angle of the rear link would this lessen rear steer and keep the same forward bite?

That would depend on the length of the rear bar compared to the front bar.Like I said the shorter the link the more reactive to a change in its angle. The shorter link travels in a sharper arc over the same travel. Get out the tape measure and take off the springs with the car (on stands of course!). Put the rear end through it's travel range from it's normal ride height and see what you get. The more you know, the faster you go!

Thanks Dman, we've lowered the front link, to see what that does and then we are going to increase angle to the rear link after we make some laps to see what that does. Thanks again.
