These are a great product but not a 5 minute job to install. The bearing and hub assembly will need to be removed. The biggest pain was getting the centre nut undone. I ended up having to heat the nut with a blow torch and then use a 1metre breaker bar. The rest of the install was very easy. The OE studs knocked out with a hammer while supporting the hub on a partially opened vice. The new ARP studs I pressed in using a press while supporting the hub on a long socket. Instead of buying new wheel nuts, I drilled out the end of my Kicks R40 wheel nuts which were not long enough for the ARP studs, then ran a 12x1.25 tap through them to ensure the threads were clean. Very happy with the end result.

Just an FYI, the site shows that it does not fit the BRZ / FR-S, but they do. :)

Good Product. Installed these with no problem. Recommend pressing them in using a nice wheel bearing. Keeps from damaging the lug and hub. So far they have been good and make it easier installing different rims/tires. I paired these with the Muteki SR48 Chrome Black Open Ended Lug Nuts 12X1.25. Works great. Nice that you can just see the end of the lug knowing that you have a perfect fit. They look good and feel ok. We rally cross the car hard and haven't broken one yet. Another tip. 4 bolts and you have the hub off. Makes it so much easier than installing while the hub is on the car. Take your time and enjoy the installation. I know we did.

I have changed my wheels to Lenso 5x114 8.5 and I added a 5mm spacers, the lug nuts have 6 turns on the OEM studs is it safe or I have to get extended wheel studs with new lug nuts?
A: I recommend running extended studs when installing any size spacer as a safety precaution.

Q: Which Open Ended Lug Nuts to Use w/ OEM Wheels? gmhl10 8 months agoAnswer
I have a 2013 STi Sedan (not Limited) with the OEM Enkei split 10-spoke wheel. Which open ended lug nuts can I use with the OEM wheels since tuner lugs are not recommended?
A: We do not recommend running any aftermarket lug nuts on stock wheels. The lug taper on aftermarket lug nuts is 60 degrees, whereas the lug seat on the stock wheels is a smaller angle. The aftermarket lug nuts will not sit correctly in the lug seat, increasing the likelihood of the lug nut backing off the stud.

Q: Returns Bryce.Robinson 10 months agoAnswer
Are these not returnable? I bought 4 packs and didn't end up needing them. I looked for the ability to return it in my order and could not find it. If they can't be returned it is a waste of $160.
A: These are able to be returned if you are inside of your 30 day purchase window, and they are not open. Feel free to log into your account and click on the invoice you purchased them on, and click return items.
