Yeah I hear you. Actually these wheels and center hub have a key which is required to remove the rim from the hub..here is apicture of the wheel. I dont have a pic of the locking center hub but it looks like a regular key, but is lasercut to prevent copying so easily....
here are the wheels I am thinking of buying....
They are made by a company called ATS. Thery are extremely strong and lightweight. I am told these are extremely rare wheels and only come in 19" and 20"...I am obviously looking for the 19"
