increase down hill nagle of upper bars, or raise uphill angle of lower bars.

This may sound really stupid but use longer springs and a small diameter sway bar. this seems to work well on stock applications.

what may seem dumb to some may sound great to others im looking for any and all ideas that people have felt helped their car on forward bite. personally we have increased the angle of the upper bars but still seeking some more hook.maybe we have gotten all we are going to get with the tire that is availible to us to use

what is the degree of your upper control arms? just for reference my lowers are about level and uppers are 25 degrees downhill. i run 205/ 70/ 15 tires and my car hooks up real good.

I agree with zero, that either way (lowers
running up or upper running downhill) will
help forward bite. So, having your upper
running downhill towards the front of the
car is good for forward bite. I would guess the uppers would react quicker because they
are considerably shorter than the lowers on
a metric frame car. But I can promise you
through personal experience that you can get
plenty of forward bite on the very slickest
of race tracks with the lowers ran uphill.
As for tweaking the uppers, there would be
several different ways to do this, but all
the ways I can think of would be cheating in
our class Maxwell.

p.s. there is a lot more to getting forward
bite out of a race car than just the rear
trailing arms. They are important of course,
but don't forget the other 2400 pounds of
stuff you can work with.

Add weight behind the rear wheels in the trunk. Just not too much, That will give too much forward bite and push. Our car has to weigh 3400 lb. We weighed 3600 lb (Clean w/ no mud) with the excess wieght but were not spinning the wheels. Shot like a rocket out of the turns. But we pushed. Removed 140 lbs from the trunk before the hot laps and were slightly loose and spinning the tires. Added 30 lbs on the right side and 15 lb on the left. The car was hooked then. Even though we were heavy, It was on the rear wheels for traction. Won the feature Last Friday, with the mud we weight 3700 lb at tech. Worked last week for me.

for gould we are running 25plus degrees downward angle to the chassis.the thing im noticing is when you get your ride height where we need it for rearsteer on the slick tracks we lose forward bite. it looks to me like our lower bar angle is fighting the upper bar angle and not allowing lift im considering floating the lower mounts on the housing to allow more rear end rotation. what do you think???
