ECS tuning posted a sale on lug bolts in the 986 section. It's an upgrade on my list so I plan to purchase. Question relates to lug bolt and running square set up. Do I need a 70mm bolt for the front and rear in order to run square? Other option is to change to 56mm up front and 70mm rear. Not sure if I'll ever switch to a square set up but if I give it a try I don't want to be stuck swapping out lug bolts multiple times.
Thanks for the help

 

The hub area of the rear wheel is thicker than the front. Also, you may find you need to run small (2-5mm) spacers on the front for clearance with the square setup. With that in mind, it would probably be a good idea to run the same size front and rear if you plan to try square.

 

+1 Put the longer ones in, no need to switch.

 

Thanks, I'll order the 70mm length studs. Already have the spacers.

 

order a couple of spares. I always seem to cross thread them just when I am putting my qualifying tires on.
