Default Lowering bolt thread size?

Does anyone happen to know what size threads (diameter and pitch) the lowering bolts that pass through the transverse leaf springs are on a C6? A 10mm wrench fits on the adjustment head, so I assume they are metric threads. Is this correct? Thanks in advance, Matt

PLEASE HELP!

I own a c6 coupe that needs to be raised higher than the stock lowering bolts allow (no more threads) I recently installed a supercharger and the additional weight is causing the bumper to drag! Ouch! My driveway is too steep entering the garage... Please advise on where I can purchase longer thread bolts. I've tried all the parts houses...nothing!?

I will try to find out today or tomorrow, I have a set of Hardbar lowering bolts I haven't installed yet, I will try to find out what size nut fits the threads here at my works mechanic shop.

Just found an old thread where a guy said it was definitely 14x2.
