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…

Springs, spacers, and a better tire.

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!
