You could always increase left side percentage and remove lf spring.

I can't help but think something is bound up, front end settings are out of whack, or a brake issue such as larger pistons on right side of car. Those rear bar angles shouldn't work at all.

Rf brake is shut off calipers are free and retract and are same size as lefts steering rack seems very firm maybe bad pump or rack thanks for any and all suggestions any one have a good set up

[Fireracer18]

Thanks masters built racer for the suggestion's

I would put a softer l/f spring in also.Might then soften both front springs

[Fireracer18]

Rcj would you go to let's say the 500 lf and a 450 to even a 425 rf

[RCJ]

It would depend on how much of a change I thought I needed.But want you have suggested sounds good.

[Fireracer18]

What if I were to put the 500 on rf and 450 on the lf and does any one have any set ups besides cj for a banked 3/8 track thanks in advance

If I remember right, Eldora's hot set up was 400 pound springs on all corners.

If I remember right, Eldora's hot set up was 400 pound springs on all corners.

That would be correct, thinking the year was around 97 or 98 but should have been long rear arms and long right side panhard bar also.

[Fireracer18]

I've herd of the 400# springs all the way around also know a guy running a 900# RR spring on a Rayburn and he was fast

Raise LR bar & lower RR Bar it will be very tight with the bars where you have them now.

[Fireracer18]

Thanks mlr19 I will change that should I add any rear steer or leave it

[MLR19]

We always started square and just use bar adjustments to tighten. If all mounts are original I would do the following on spring rates:

LF 500 RF 525 (or 500 if you dont have a 525)
LR 275 RR 275 on Birdcage or 500 on swingarm
240 lbs LR
54.5% LS
56 - 57% rear
3.5" to 4" of stagger

Start LR bar 2 holes up from bottom
Start RR 1 hole up from bottom

If its tight on entry go down on LF spring rate at least 50 lbs
to tighten off the corner raise rr bar1 hole at a time, if car is coming off the corner straight & you just need more drive, start softening LR spring 200 usually works well on slick. Make sure to put wedge back to 240 when changing springs.

MLR19,
When you say bar, I assume your referring to trailing arms. If so, what were your Swing Arm angles? Thank you for posting this info!
