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
