i ordered these from http://www.summitracing.com . i know a lot of people have hard-on's for light lugnuts, but they break (kyokugen) or they pay silly $ (rays). these mcgard's are not light, but they are very strong and durable; same manufacturer as oem lugnuts. summit has them for $11.39/4 nuts. it's just another option.

versus oem, big nutz y0!

lugnut 101. note the spherical mating surface of the oem nut - very specific to wheels with spherical mating surface. the new mcgard nut has a conical mating surface - most aftermarket wheels can only use the conical nuts.
don't mix your spherical with your conical!

 

you can't use these with oem wheels tho...

 

Those are some mighty big nutz

Are they open ended? Looks like it....

 

"tough nuts"

 

...I would buy the wheels first and then look for the right lugs.

 

*Insert dirty joke here*

 

these work perfectly with millenia wheels and i'm going to order new wheels soon. the conical lugnuts will work with any wheel using conical lug holes.

 

nope, but they are much longer than oem so you could potentially get longer studs.
