Seeking sway bar advice

Was your 240 the black car that used to run at PCA events? Yes bigger front bar definitely helps with getting more power down in rear. Biggest stickiest rear tire

A good adjustable shock will help too. That stock LSD sucks but if you are running stock that's the one you have to run.

The black car is a good friend of mine, however my car is yellow with silver/grey BRE stripes #101. I also used to run it at the PCA events when ESCA members were allowed to run PCA events since we share the same surface on the backside of the Sonoma County Airport. Unfortunately PCA doesn't allow this anymore.
Thanks for the replies so far. SCCA now allows you to change either front or rear bar in stock class. It seems that for an otherwise stock car perhaps the stiffest might not be best so as to not totally unbalance the car. It seems like i could end up with lots of understeer. I have seen "crash bolts" for front camber adjustment (tire rack) which seems like perhaps a good match with the front bar change, but i'm not sure the legality of this in stock. I have talked to people about this, but never seem to get a clear answer.

As long as you get big tires under the front and give the car an AX alignment you won't have an issue with understeer. Just put small amount of toe out upfront and car will turn. I may be mistaken but don't think those bolts would do anything for our suspension. You need to do something with upper arm which would be against rules in stock. In stock class if rule doesn't say you can do something you can't do it. No gray area.

Currently running rs3's on stock Rays wheels, 245/40/19 front and 275/35/19 rear. Has anyone tried the any of the various bars available? Hotchkis seems to stiff at "205%" stiffer. If I remember correctly (looked at so many now I'm hallucinating) Stillen is 25-48% stiffer. I'm somewhat confused about why so much variance. Not real clear on wall thickness, etc. Wish i could find an adjustable bar where softest setting started at about stock and went up from there.
I have considered disconnecting the rear bar, but i think stiffening the front will have a better affect by allowing the car to shift weight faster and have better rear grip. Thanks.
