Hi all, I just picked up the 2023 IS 350 RWD F Sport. To my surprise it has lug bolts, I never own any car with lug bolts, so what's the BEST brand for aftermarket lug bolts in terms of strength? Preferably floating seat if possible.
I have some staggered setup 18" TE37s I'm guessing factory lug bolts won't work, either due to seating shape or too big to put a socket over it and scratch the inner wheel lug hole.

Thanks in advance

FYI I edited the thread title to 2021+, since 2021 Model Year (US) will have lug bolts, but not 2020.

Thanks, I was looking at wikipedia page of Lexus IS that worldwide facelift happened 2020 and didn't do my due diligence for US

Answer

There's a bunch of options for conical seats which will fit most aftermarket wheels like the TE37's. Stock ones are spherical so they won't work on pretty much everything other than stock wheels.

Thanks, I'm thinking these ones

Do you know what length to pick? I don't plan on using spacers, just directly wheel to rotor

Answer

I think the stock ones are 28mm, but don't quote me on that and mesure one to make sure!

good timing, I found out I got a nail this morning and had to remove the wheel and bring it to discount tire


looks like they are indeed 28mm, thank you.

Also, I feel these bolts were under torqued from factory, if they were really torqued to spec 103 pound feet, I wouldn't have been able to just loosen them with a 3/8 wrench. I'm going to re torque all the bolts later

This company has a good selection of lug bolts of varying lengths, all manufactured in Europe. The set I purchased from them were made in Italy by Farad.

Did you end up getting these? How are they?

So these are basically BMW bolts, at least if the Supra is re-using BMW parts and the IS is using Supra parts. And really they all likely come from the same supplier, at least for german OE. bmw, mbz, vag, etc

but either way I have a long history of cars with wheel bolts and to me they are the superior choice. Back then, the thing was "make sure you get grade 8 or higher bolts."

so that's what I look for, from a reputable seller. H&R motorsports the premiere aftermarket part place for BMWs used to sell a wheel bolt kit. extended. i'm sure they still do. Check ECSTuning as well, an old school german tuner parts place. germans have been using wheel bolts for decades, so check the german parts places.

If you must have Japan-made parts, you could go Tom's as well.

Appreciate the other insights, just want to clarify that the Supra is re-using BMW bolts but they differ from the Lexus line-up. (I owned a GR Supra)
Supra utilizes M12 - which kind of surprised me. So unfortunately my wheel hangers I had for that car don't work on our IS500 haha.

I would suggest doing a conversion studs which you wont have any issue with any set of wheels.

Yeah I suggest going stud conversion also. That's the route I took.
I went M14 to M12 Conversion so i can use my stash of lugnuts I've collected over the years that fit Toyota/Lexus and Honda/Acura.
The only bad is you have to use open ended lugnuts with the studs I went with
