How many Lbs do I tighten these wheels to? One book says 90, the next says100 and anouther says 80. What do you GTA owner's use?

i use 87 ft/lbs for all wheels unless the wheel maker says otherwise, like my welds only get 60 ft/lbs

I use 87 also. I have heard ~107 is what the manual says. My manual for a 90 bird says 87 so that's what I use.
