Spacers are easy, the H&R spacers intended for is350/gs350 work on our cars.
The issue is, you won’t be bolting the spacers to the hub. You either do a stud conversion with lug nuts (porsche style if using stock bbs wheels).
or you get longer wheel bolts, also porsche style if stock wheels.
The hub interface is very positive, it’s so long (like 12mm?) that the spacer is held on by friction…not quite a machined fit but close.
My lug conversion came from Motorsport Hardware. I stayed with 14 size. Some people convert to 12 to work with aftermarket wheels.

If I'm understanding correctly, this would be the Porsche Style wheel stud conversion kit, I'm not sure what length to get. Since I don't know the stock length of the front and rear studs, i know we'd add 15mm to the front, and 20mm to the rear to whatever starting length we have.

My math….
I pulled a lug and mic’d it.
18 threads per 28mm
8 threads appear to enter the hub, 10 threads are left for lug bolt/wheel. Adding a nut, you’d need appx 20 threads beyond the hub. 25 to be safe. This is appx 55mm in threads before the 15/20mm spacer. Adding the spacers, would put us in the 70/75mm length needed. The Motorsport Hardware 78mm kit should work for length.
I went to order this, along with the Porsche ball style black lug bolts in 14x1.5…..and now I can’t find the H&R spacers in the 14, only the 12. Going the 12 route, I can’t find ball-style 12x1.5 black lug nuts (through stud type).
WTF.
Without knowing the exact length on the 14x1.5 Porsche ball lug bolts, replacing like factory without studs, I wouldn’t be comfortable ordering not knowing if they were the correct length or not. And not sure how to measure that, with different sized spacers front/rear. I don’t want to run different sized lug bolts.

I would just buy the spacers, throw out the studs they come with, and buy longer M14 ball seat bolts and call it a day.

Thanks @FI4runner for the reply and work you put into it. I don't know why this is so hard to find out the correct information on what and where to order from. It is a bit frustrating, I have my IS500 springs on now from RSR and its definitely an improved stance, I'd like to push those wheels out just a bit.

This seems to be the only thing I can find that specifically mentions the IS500 and you can customize the size and get longer bolts included on the site that it won't let me post, just search for IS500 Wheel Spacers, its starts with a B
Not sure of the quality, reading the About Us on the site it says, Founded in 2007, Guangzhou Zhongpeng Auto Parts Co., Limited, I think that's self explanatory where they're made.

I’m not sure what the policy is with linking to stores on this forum so I’ll just say that you could search online for H&R spacers for the IS or GS. They will have the same bolt pattern and center bore as what you’re looking for. They come with M12 studs but they will be useless since the IS500 uses bolts. If you are looking for them to include M14 studs, I don’t think they carry that combination.
I would just buy the spacers, throw out the studs they come with, and buy longer M14 ball seat bolts and call it a day.

If I’m sourcing and installing 14x1.5 studs from elsewhere, are the spacers with a 12mm hole going to fit over a 14mm stud? I didn’t think they would, but I do not know. I guess it depends on how large H&R drilled the holes through their spacers.
I PM the OP to ask as well. Hopefully he can confirm.

I did find the older Lexus H&R 5/114.3, 60.1 bore but with the 12x1.5 thread type.

Edit: I was referring to the kit I am purchasing, not the H&R when referencing the longer bolts.

can you link the exact bolts you went with? The ones i found were r14 with moving washer at a max length of 58mm.

They do fit. I am running 15mm F/R H&R from their RC/GS spec until my forged kit comes in, but that is not a stud conversion. It comes with corresponding longer bolts. I just wanted to keep it as OE spec as possible; that is personal preference though.
Edit: I was referring to the kit I am purchasing, not the H&R when referencing the longer bolts.

I will order everything up and keep this thread posted.
