Hello. Just purchased an a-spec and will be changing out the silver lug nuts with black ones/wheel lock. Is it safe to change on lug nut a time...while the wheel is on the car/ground? Also since the a-spec has the 20" wheels, is the torque still at 80? Thank you.

 

Should not be a problem but I would look in the manual and find the torque to verify it after you change them all.

 

I swapped mine out for black lugs with the car on the ground with no problem. And yes, it is 80ft/lb of torque.

 

You can swap them out one at a time, but I would not tighten them to full torque one at a time, just replace one by one and only tighten snug. Then torque them to 80lb-ft in a star pattern going multiple passes

 

Gotcha, thanks guys!
