can you believe it? another torsion bar question?? 1.03" vs 1.08"

Yes. Before you ask, yes, I looked. In fact being autistic.. I've probably spent far too many DAYS total researching this... but just can't come to a solid conclusion. So lets cut to the chase:

'64 valiant with 5.9 360 in it. Planning on tracking/ time attack eventually. Most information I see on here is either regarding drag, autocross, or daily. I feel none of these are EXACTLY what I'll be doing. Will I (unofficially) drag? Maybe a bit. Will I daily? Yes. Track events/ time attacks? Yes. Autocross? No. I've daily'd quite "harsh" cars before so I'm not overly concerned with ride quality, as I'm sure it won't be worse than some of my other more track dedicated cars in the past.

I am TORN between the p-s-t 1.03" and the swayaway 1.08". I've seen all the happy customers swearing by p-s-t, and see that BAC recommends starting at 1.08" for a performance feel. Best I can find, based off swayaway's site information, 1.03" are roughly 242 lb/in while 1.08" are 292lb/in so really not a huge difference there.

So... here's the issue... my brain keeps saying get 1.08"s. Swayaway is local, and would come out to just under $400 after tax. P-S-T offers a 10% discount so those would come out to around $300. Given the larger motor etc, will the 1.03" still cut it or should I increase to the 1.08"s.... or even larger if it's recommended(doubtful)?

Ugh.... please help guide my brain... I know everyone says can't beat p-s-t's price but something is just stabbing my brain saying I should get the 1.08"s instead. Would LOVE some input to put this idiotic mind to rest
