I looked at this again this weekend Just be warned that due to the geometry of the knuckle and additional spacing will push the caster back and can have impacts on the steering response. It may also make more tire interference depending on how thick it is and what tireyou run.
RCA spacers were originally designed for flat knuckle vehicles, but the gen2 IS and Gen 3 GS have a slanted knuckle.

Yes, this is an easy way to drop the suspension. No, it is not without negative impact on the suspension's design. That's frustrating, but at least it's pretty clear this won't work well for track driven cars.

Totally agree with the comments above. When I run on track or autokhana, I'll be removing my spacers. I'll leave them on for the street for the aesthetics.
I'm one of the few strange people who is satisfied with the OEM suspension. I'll improve my driving style before making major changes to the car.

Just a quick update last week I put the car back to stock the handing characteristics return that's just the way I like it to me performance outweighs asthetics. I'm no expert but there may be some long term damage to suspension by keeping these spaces in for any length of time. Just like VJ stated anyone looking for small drop just go with swift spring and set of FIGS Mega Arms and call it day.

Just bought this kit and was planning on installing but i'm not liking what you guys are saying about how it won't work well with a track driven car. I drive my car on the track often but also want to lower just the front. I had also purchased a set of swift springs. My main question is...is it safe to drive on track with installing only the front swift springs and continue to run the stock springs on the back?

Tonnetje if you read thread you would see that this lowering kit will not work on second gen ISF, IS350/250 this kit changes the geometry of the suspension. Which in turn effects several ares of suspension most notably being caster.If you want to lower your IS get springs or coilovers.

Do not use RCA spacers for the IS F. It will mess with the caster as mentioned in this thread many times. I had them previously installed and you can tell the wheel is off-centered in the fender. Not to mention it throws the whole car out of sync while driving. Do yourself a favor and get coils. I regretted not doing so in the first place. I sold my set to a better suited application on a GS.
