I'm shopping for wheel locks. Pretty much sold on the Gorilla brand. (I've known many people who snapped their McGard - flower pattern - keys... no good IMO.)

So I'm pretty sure on what thread size to get for my tC:

12mmx 1.5" (Please, let me know if this is wrong.)

Now, what kind of lug nut seat style should I get:

Conical Seat
or
Shank

What is the difference???

Also, any opinions on the different models:

Gorilla Guard II Wheel Locks
Gorilla Guard Wheel Locks
Gorilla Wheel Locks

These locks are on the Summit Racing website:

Any opinions or suggestions on a good retailer that sells these?

TIA

I ended up with black chrome gorilla locks - 12x1.5 - with a cone seat.
Purchased them from the local Discount tire center since they are the largest seller of Gorilla here in SoCal. Had to order mine since I wanted black - $25

here is a great site for nuts and locks :eyes: http://www.brandsport.com/manufacturers-gorilla.html
