I narrowed my search and I came upon more choices ;

Open end Design ;
No, Yes

Which ones should I choose In these options?

Thanks for the answer Stephen

 

standard and locking gives you 4 regular and one locking lug per wheel. so that is your choice if you want locking lugs on your wheels. tuner style is a odd design i don;t like the look of them. it a special key socket to install and remove them. it looks like a gear or spline design.

no idea on shank size

conical seat

closed design, this is a chrome over top of nut, if you say yes to open you will see stud inside nut. not what you want.

usually you order 12x1.5 mm closed design conical seat. that should get you want you need just decide on locks or not.

Actually, most tuner style lugs have an 8pt star opening which most people don’t seem to know is designed to work with a standard 4 sided 3/8” drive extension. They do make sum that need a separate “key” but they are just 6 sided hexes, just a big allen key like your brake pins use.

As far as what will work for you… the stock studs are fairly sort so pretty much any 12x1.5 lug nut with a 60* tapered seat will work fine. Just choose one you like the looks of.

 

Oh, and there are also “spline drive” tuner lugs that have 7 or 8 splines on the outside (depending on the brand and design) that sorta look like GM locking lug nuts but the splines are evenly spaced where the GM ones are in an odd pattern to match a key
