Thread: arp extended studs

well ive done some searches to find what arp extended wheel studs would fit my b14 and i havent found one for the nissan but i also found that the wrx ones will fit. my question is will it work?

There are two commonly considered ARP wheels studs that will fit. The WRX ones are very expensive (Edit: No longer expensive!) but provide the best fit (perfect in my opinion). The other option is a much cheaper stud with a less than ideal knurl diameter and much longer section of knurl that may interfere with your brake rotor (my own conjecture from seeing their pictures). Many of us (myself included) have spent the extra money on the WRX studs and are very satisfied.

Here's a thread that might help you decide:

And here are the two part numbers in question:
ARP Part # 100-7716
ARP Part # 100-7766

The ones I got where designed for some kit car. I got them really cheap though. Mainly wanted the normal 12x1.5 thread pattern lol.

thanks for the help guys

I forgot to say, the WRX studs are also the same thread pitch as OEM at 12x1.25 where as the other option is 12x1.5. You're going to want to buy open lug nuts as it's hard to find closed that are deep enough and some sanctioning bodies (NHRA comes to mind) require open lug nuts with extended studs.

so i wana get some extende studs for my nx and rum a 10mm spacer in front and a 15mm spacer in back....were can i get these longer studs from that will work with my oem rims and lug nuts?

I got mine from www.summitracing.com. Here's the link: ARP 100-7716 - ARP Wheel Studs - summitracing.com

You'll need to buy 4 sets of 5 to get enough for an entire car.

I also bought 4 sets of Gorilla open lug nuts. Here's the link: Gorilla Automotive 30027 - Gorilla Lug Nuts - summitracing.com

If the lug nuts you have already are open, you can re-use them instead.

Edit: Don't buy from Summit. Much better pricing here:

Do you have any of the 4 extra studs left that you might be willing to sell? I would really only need 1, maybe 2 in case I screwed one up.

I sure do. I should have 4 left in a box. I can get ahold of them sometime this week and take pics if you want (they are not at my place at the moment). They are brand new and all that jazz. Let me know if you want 1 or 2 and I'll set up a for sale thread for yah.

thanks
