I bought a set of Fsport springs for my AWD and ran them for about a month. I got an awesome deal on some used BC coilovers, so the F-sports are now up for grabs. These are the revised version, this part number is for the IS250 AWD, and IS350.
The part number is PTR07-53090. They will come in the original box with the installation instructions. Any questions or for pics, email me at Walker923@gmail.com
