More camber in both tires. Soften LF spring more than 30pds. Try a 500. Do you run spoilers? If so they seem to really tighten entry.

Never heard of anyone running a straight valve rf shock on a modified under any conditions any circumstances.
call up bob harris and gets some modified shocks from him.
His jri package is incredible, they are all bv. When I bolted them on my car it was like a new car. 6-7 would cover all track conditions.
rr base
rf base to run on lf
rf dry
lr base
rr heavy
lr dry afco
rf heavy
would be 3 adjustment shocks and cover every condition
he doesnt call them this he has rates on them but hell know what Im talking aboutComment

I can agree with ya the shocks are important but when the car isn't even close yet the shocks will not take me from mid pack to the front. I already have a shock guy and he is very good. When I have some consistent handling I'll reevaluate my current shock package.
Today I took the springs out and smashed em. Now here's the thing on my missing set up notes. Both spring in the front rated at 580lbs and not what's marked. Now that this has come to light I do remember having these tested before and since then the tag is no longer there.
For this coming week I'm putting in a 620RF and 580LF and reducing LRB to 40-60lbs. I would have left the RF alone but I don't have anything lower than a 580 at the moment. I'm also taking out some LRU and RRU bar angle by going down one hole and the RRL I'll start 1 hole up from level. Hopefully entry and the middle will get better and the less forward drive will be needed.Comment

Personally, I'd change the RF shock first before I did anything. I don't see a point in adjusting the car to neutral and then changing the shock package and having to relearn/adjust the set-up. I only say this cause your so far off a typical RF shock valving, that getting just semi close there will make a huge difference.Originally posted by Lizardracing View PostComment

What do you recommend?Comment

Get some rebound in the RF. While the old numbering system don't really tell you squat about a shock today, get something in the rebound range of a 10. With something in the range of a 4 rebound, the RF has to be coming completely back up at the end of the straight and so when you let off getting into the corner I'd bet the RF dives pretty hard. This in it's self will cause you consistency problems and just getting some rebound in the RF will likely get rid of a ton of your tight issues.Originally posted by Lizardracing View PostComment

I'll talk to my shock guy today. Thanks!Comment

You need to get some low-speed rebound in the shock. Somewhere around 250lbs at 3" and 350 at 6" should be in the ball park. That'd be close to a generic 4 compression 8 rebound. Ideally, you'd get some zero point in the shock - somewhere around 100-150lbs would make a world of difference.Comment

If you HAVE a shock guy and he supposedly advised you to run the 4 you listed you need a new shock guy.
450 each will get you some great shocksComment

Digging this up from the graveyard of posts.
I got some good shocks. My shock guy found me a good deal and now I'm on:
RF: 4-8
LF: 6-3
RR: 4-6
LR: 8-2
It's helped. The car doesn't push on the throttle anymore but it's not enough.
The next week broke a pushrod.
The next week a hole showed up in the oil pan.
Then another hole showed up in the oil pan.
Then the ignition switch went bad.
The following week the Pull Bar broke and I sat out for 6 weeks fixing all that and going over everything on the car trying to shake the monkey.
We have three weeks left now.
Last week the car was decent. Still a little tight on entry in hotlaps.
I moved the J Bar up on the pinion to 3.5 rake. That makes the straight part of the Jbar level.
The car was much better in hotlaps. Still a little snug on entry but turned well on the throttle and forward bite was good when pointed in the right direction.
Just trying something I put 4lbs of air in the RF and 4lbs in the LR to loosen entry more.
Car was okay but not great. Entry was a bit freer but still needed a little brake on entry but it still rotated well on the throttle and forward bite was good.
We left it alone for the feature hoping the track would come to me but it didn't. Car was free enough on entry but lacked side bite in the middle. Forward bite was good once pointed straight but the lack of side bite in the middle was frustrating. When I could get the LF up on the inside burm the RR would stick better but someone hit the tire and I couldn't do that for the last half of the race. We finished 10th but I want more.
Someone tell me what to do here.
More RF spring?
More LRB?
More Jbar angle in the slick?
All three?
Sincerely frustrated.....Comment

I would switch to 200# springs across the back. Raise the lr ride height 1/2 inch.Comment
