unless you are running a swingarm on the LR then that spring is probably a little too big. drop to a 225 or 200 like u said. That'll loosen exit and you can try it, it may fix the whole problem due to that spring being that far off.

Here are some of my ideas. I agree with 17 drop that spring rate on the lr.
then you could lower rear % that will help to free it up all over.
you could also clamp the rr spring in front, that will free up entry and exit.

I agree, lower that LR spring to a 225, also make sure the rearend is not trailing the LR.

I would think you could move the whole rear tracking over to the right some. Push out the RR and bring in the LR with different offsets. You'd want to redo your scale numbers after the change though.

what kind of tires are you running, if your on the imca tires 1 inch stagger is probably right for tacky tracks but on hoosiers you seem to need more than that.

why would it matter what tire you run? you still need the stagger to help the car turn. 1" in front and shoot for 2" in the rear. Think of stagger like rolling a styrofoam cup on the floor. What happens when you roll it? It turns!!

If it were me, I'd go down to a 250 on the arm LR, I'd also move the rearend to the right 1/2 inch. This should loosen you up enough. Stagger will only help if everything else is in working order.

the hoosier tires have a lot more bite then the mccrearys so we have to run more stagger with them to make the car turn.
with the imca tires we usually never ran more than 1" or so, and sometimes 0, where with the hoosiers we never usually go under 1" and sometimes up to 3"

I have the same set up as you and had the same problem. I had a 250 in the LR with the spring in front and a 175 on top of housing on RR with a short pan hard bar. I put a 200 spring in the LR and moved the pan hard bar up 11/2 inches on both sides. This help the car alot and it was just a little tight but I put more rear brake in the car and threw it in harder. I could run below any body that night on the bottom. It was a little too loose for the top dry stuff. If you are still a little tight put a round or so in the LF. Hope this helps

Maybe a dumb question, but have the checked the wheelbase, since you're tight in and out? I worked on a car for two nights, throwing everything at it, to discover it was long on the right, because I left it to someone else to CHECK THE WHEELBASE, before we scaled the car.

We were down to 46% cross and 53% rear at the track and still not turning..... I think it was 3/4 long on the right.

I don't think it is possible to overcome too much length with springs and angles and jack bolts.

Better safe than sorry. Disregard if necessary.

Good luck.
