Arp contact info? and quick question

[blackbombshell95]

Does arp have a website. i went to arp-stud.com and it doesn't work

As for the Part #'s off this site

8 - Undercut Long studs (11mm x 1.5 & 7/16" - 20) - ATP5.4LU

8 - Undercut Short studs (11mm x 1.5 & 7/16" - 20) - ATP4.650LU

16 - Hex Nuts (7/16" - 20) - APN58 or 12 point nuts (7/16" - 20) - APN12-1
16 - Washers (7/16" ID 13/16 OD) - APW1316N

Now in the bold there. I have the choice of either one? or do I get both? Since i see the "OR" in there. Or am i just simply confused.

You mean the NUT. Well you wanna use a 6 point socket or a 12 point socket?.. Usually 12 point sockets have more to grab on to the nut while torquing. Yet..most impact sockets I have use a 6 point. Guess its more of if you like the look of a 6 point or 12 point. 12 point looks more high tech....I guess.

It used to be ARPracing.com. But looks like they are going for an update

Oh and you have numbers for 7/16 studs. But unless its something other than a 660 that is not the right stud.

[blackbombshell95]

its for a 02 3400

Uhh yea you had 7/16-20 nuts listed there. That sure isn't right if you using them on the 11mm studs.

I made a mistake before you have the right studs but wrong nuts and washers.

7/16" nuts are the correct ones to use with these studs.
