How to Install ARP Extended Wheel Studs on GR86 (And Why 20mm Spacers Still Won't Fit)

This video is a quick how to video of installing extended studs, and things to consider when choosing slip on spacers. Did I waste my time on this mod? I don’t think so. I definitely learned a lot and got really acquainted with the suspension of the car.

Thanks for this video! Going to try installing my 15mm spacer with 2.5 arp studs this weekend

[@LEEMWEEZY]

Nice! Yeah 15mm is probably the way to go with the 2.5 inch studs. I also heard some people have had luck squeezing in 3 inch studs on without removing the axle nut. Something I may experiment with in the future.

Great video man - thanks for taking the time to help us with the process. Seems really straightforward. So what do you think? Think you'll go 15mm all around or get 3" lugs?

[@LEEMWEEZY]

I actually went with 12mm spacers all around. And with that I can lock in 13 threads. (New video next week).
15mm def would’ve been doable, but I didn’t want to make another costly mistake because these are non returnable. You only need 9.6 turns to properly engage this thread pitch safely. (12 divided by 1.25)

interesting.. I have a similar setup. just recently got the 3'' arp studs and 20mm spacers. I will see how this fits after installing them. if im not comfortable with the amount of thread left, I might try a smaller size spacer. maybe a 15mm?

[@LEEMWEEZY]

I think that should work perfect. I kept the 2.5 inch studs on and installed 12mm spacers. To be honest, I could’ve gone 15mm with the current set up.
But if you’re doing 3 inch studs, I think you’re golden with 20mm.

can i ask what brand and model is your impact wrench? I need to replace some wheel studs on my 22 BRZ - tire shop over tightened, I think they're cross threaded, so I'm looking for a not too heavy impact wrench.

[@LEEMWEEZY]

It’s a Makita XWT15Z. Kind of on the pricey side, but I think the auto slow feature is nice and worth it so it doesn’t over do it.
