these look like they've had a rough life, any idea how many miles they have on them?

they're just dirty

was told 20k. koni yellows have a lifetime warranty anyway, and I still have the install/adjustment paperwork

fyi, is300 and gs300 suspension are not interchangeable!

News to me? These came off an is300, and have same upper mounts as a GS, and +/-.125 identical shock length

Guys on Club Lexus run IS3 on GS3 regularly

The coils will physically bolt in place, however the GS weighs about 450lbs more than the IS. The coilovers for the GS will usually have stiffer springs to counter the added weight. You can use the IS coilovers, but the spring rate and dampening would probably be incorrect for the car.

no, the tophats and bottom bushing mounts are different!
