Last week the car was pretty fast, but not winning fast. We feel like we need to make a slight adjustment to move to the front. Street stock style car. The two issues may be connected. Slight push in and loose off. Jacking bolts in the front only. Springs-225LR/175RR/1100LF/1200RF Shocks-4/4LR,3/5RR,4/4LF,5/3Rf. Offsets RR4, RF2, LR21/2, LF3. %s- L53.9, R50.3, C53.2. Total weight w/driver and fuel 3287, must weigh 3200. Driver complains mostly about loose off. Track is 5/8 medium bank high speed.

I would think soften the front springs to fix entry and that should help exit

It's hard enough trying to give me some good advice, but I gave the wrong information. The LR and LF shocks are both 4/4 valving. Thanks for trying.

soften LF spring by 50lb. that should loosen entry and tighten exit.

when the driver says slight push on entry, is this on or off throttle?
you could do as I stated above and soften LF spring rate if push is off throttle
you can also increase LR spring rate, that will loosen off throttle handling as well

both should help your exit.

also, you are not mentioning tire type, or stagger

You could get rid of the 4 off on the right rear and try a 3 or 2. That could help your push, and probably fix the exit in the process.

Fix the push on entry and your exit will be better. There is not near enough information to tell you what you need to do. Spring or shock change, maybe? Might be as simple as taking the anti dive out of the RF and increasing your caster split to get it to turn in better. Spring change is a big adjustment, I would make sure the smaller things are working for you not against you before I go for that. Just my .02
