trying to cure a tight on entry problem and need some suggestions.
car is a pierce car and with 750lf 650 rf 200 across rear with rr on top
lr top bar is a around 20* up and bottom is level
rr top is 5 down and lower is level.
zero lead in rearend
52.8 left side 49 cross and 57 rear
53 bite
2 inches front and back staggers.
tried a 700 spring in rf on a flat high speed track and driver didnt like it along with moving rr spring in front housing
going to run a tight banked 1/4 mile track Friday night Gas City Speedway
Question should i put the 700 back in or what??
This is track where we really have the tight in problem

Have you tried more cross?

Clamped up LR? 4 bar?

We run a Pierce and had the same problem
On a wet track we run a 1" wheel spacer in the lf to lower the spring rate to free it up on entry, and we lowered our shock #s in the front and it helped a lot.
Are your link lengths in the back at the right lengths.
every thing else you got there sounds right
we run less bite than you too.

thanks i was thinking of adding some cross
yes its clamped in front.
I have a few quarter inch spacers but not a one inch, our darn studs are not real long either
what shock numbers did u run up front?
maybe u could email me ur numbers Don and compare to what I have, do u run BP shocks?

You might also consider trying a SLIGHTLY stiffer RR spring before changing everything else and possibly creating another problem somewhere else, its quick and easy and might be all you really need to do, just a thought, good luck!

I had the same problem with a 4 bar lr and 3 link rr. LR is floated and RR is clamped. I put the rr on (3link) swingarm and dropped my cross weight and it helped tremendously. If I remember correct, from what I read more cross % tightens it up.

more cross weight frees up when going into corner,when letting off
also a higher spring on rr will tighten it more adding more side bite to car,
i think we have her figured out
