Just a heads up-
I recently went w/ 20mm bolt ons all the way around and experienced a nasty shake in the wheel due to the OEM studs hitting the back of the front wheels. Some of our Z's were produced with longer studs than others. I have the sport Rays and the space in the back of the wheel still does not allow the studs to sit without any contact. Many advised on cutting my factory studs a few mm but that just sounded like a bad idea. I took a loss and sold them. Went with the stud replacements instead.
If you're looking for a pair of 20mm boltons- Id advise them only to be going on the rear. Don't make the same stupid mistake I did.
I was just banking my Z had the shorter of the studs from the factory lol....
If you are like me, and hate doing shi* twice, don't gamble with boltons on the front...
Just my .02
