Spa Tub Install

I'm installing a Spa tub in an alcove. The tub (an American Standard Cadet Spa) has four feet that you level with shims. I have to put Leveling Stringers on that should contact the tub but not support any weight. I shimmed the four feet with Cedar shims and my question is how much will the tub settle down when it is filled with water (around 800 lbs)? Should I place the Leveling Stringers tight to the tub or not? Is there a different type of shim I should use?
Thank You for any guidance you can give me.

Thanks but maybe a little more info...

My question was not should I use stringers, my question was and is will the cedar shims compress with the weight of the tub? Should I leave a gap between the stringers and tub to compensate for the cedar shims compressing? Or place the stringers tight to the tub?
