Nice Nuts
These nuts fit the sport/compact cars like you would expect. Just make sure to only use these with racing wheels, as using them with stock wheels will cause the wheel to crack (especially if over-tightened).

I like these but my use for them was for installing wheel studs and I chose them because of the large flat surface, theses with a hard flat washer and a little grease worked better than anything I used before they are tough and made installation a breeze! 👍👍👍
