Haven’t seen the Eibach and I have swift. RSR seemed to low in the rear and even the swift claims lower front than rear but that’s not what I observe. Overall I love the look with spacers but I think the suspension could use more than just springs if it’s handling you are interested in. Lowering it reduces understeer it feels but now my rear end feels different. Or maybe it’s just after 7k miles I need new tires…

So as far as I can tell, the 15mm spacers sit flush on the rear of my car, although Bonos advised me otherwise. So maybe other people will have problems? I don’t know. But attached below is my crude collage, hopefully helps someone. Fronts had same results.

Do you have a white IS 500? I just saw a dude’s YT vid on the Bonos brand and he used the exact same size. If this is you, well done…the car looks awesome!

not me, mine is black. I ended up going with the 15mm Bonos in the back as I personally thought it looked best at oem ride height. May move to 20mm once lowered.

How does it look on the stock springs? I live in Houston and worried if I lower the car I will kill it on these roads. 😂

IS500 weighs about 100lbs more than the 350. I wonder if these would fit well.

I'm running into similar issue with ****** where they're saying that the 15mm won't fit the rear of my car. I'm not sure I want to roll the dice and would rather go with H&R. That said, the H&R website is complete garbage and I can't for the life of me figure out what the part number is. Would you be able to recommend 15mm spacers all the way around with H&R for a 23 IS500? Do you also happen to know if it's possible to keep the lug bolts or are we required to convert?

Thank you in advance for your help!

Can you measure if those are actually 10mm spacers? BONOS doesn't sell them and won't custom make one for me

I've been trying to figure out how you fit 10mm hub centric spacers but it seems physically impossible given the front hub lip is 14.3mm/Rear hub lip is 14.8mm, and both the hub and wheel are 60.1mm

Default After springs and spacers 15/20mm

So I am now looking into spacers and what it appears is that the 2022 IS500 which I have cannot fit a 15mm spacers due to the flange size. Is that correct? For this who installed 15mm in front and 20mm in rear like the look? I honestly want to do 15’s all around but do not want to run into this issue. Can someone please advise as I am getting the same feedback from Bonoss that 15mm will not work in the rear.
