a 1/2" size torque wrench allowing you to torque to 100 lb-ft for normal stuff, and up to 140 lb-ft for heavy duty like 3/4 and 1-ton trucks having larger lugs.
Deep well 1/2" sockets sized: 3/4", 13/16", 7/8", and 19, 21, 22 millimeter.
and not more than two 1/2" extensions of appropriate length, maybe 1.5" and 3" long, don't think you'd ever need longer than 4.5" extension. and better to have a dedicated 1/2" ratchet with a piece of ~16" black pipe that fits over the handle for removing lugs, don't want to use a torque wrench for that.
It's said impact sockets are softer which prevents them for breaking when using an impact gun, but it results (or can result) in inaccurate torque readings when tightening. how true that is and if it matters for lugnut tq accuracy around 100 lb-ft i don't know.
