I want to get some red lug nuts on my coupe, but not sure what length I need. I've been looking at the HR Autopats thread: https://g35driver.com/forums/wheels-tires-vendor/207277-lug-nuts-muteki-kics-rays-work.html

Not sure what the numbers mean. Are the 20 x 21, 34, 35, 48 in mm's? I'm going to try to get one of my lugs off the car to measure it, because I have no idea what they put on after I got my new wheels, but they are one-piece forged without any fancy reverse mount so not much has changed. The lugs are really deep inside the wheel too, so I am suspecting they are just regular length.

I was also wondering if it is BAD to get longer lugs than necessary; for example if I have normal length and get extended. Last thing, these mostly come with keys. Are these like wheel locks? I'm used to my previous car, where I just had 5 lugs and 1 special wheel lock. Have they changed that to just all lugs having a unique key or something, or do I still need to get a wheel lock pack?

Oh and any brand better than another; Muteki, Rays, Work?

Thanks in advance.

If you don't have aftermarket wheels -
Aftermarket lug nuts are a no go.

they are after market. the stock lug wrench that comes with the car doesn't fit at all (it's too big). The new lug socket size is a 12mm (but uses a key). I'll try to get one out tonight and measure it.

I got some info from HR Autoparts that says that extended lugs will be just fine on normal length studs and would just be for looks. That true? Any abnormal wear or anything weird happens if I put extended lugs on normal sized studs? Just making sure I don't end up causing damage with my dress-up mods.

bump and also:

talked to the guy at les schwab that helps me out all the time today about extended lugs. He said that getting over-extended lugs can lead to moisture build-up inside the unused space and eventually to corrosion. Sound about right? He said the solution would be to get open-ended lugs.

Not true at all. It is only if you have mag-style lug's from the factory (mostly on toyota's)

If the car comes with acorn style lug nuts from the factory then it is perfectly fine to use aftermarket lug nuts on factory wheels.

To the OP... You wont cause any harm by using extended lugs on normal length studs, it's been done a million times.
