Im about to paint my calipers.. and was wondering if I must have a torque wrench to make sure my lugs are put back on right?

or can i just use the wrench that comes with the car and just tighten them as much as possible?

 

You typically want to re-torque your lugs after 50 miles with alloy wheels. It will be just fine to use the wrench included with the Lexus.
