Bilstein B14 PSS Coilover Suspension Kit 2013-2024 BRZ / 2013-2016 FRS / 2017-2021 GT86 / 2022-2024 GR86

After 6 months of using this on my 2013 BRZ I just can say these are perfect, I still hasn't touch the height, left them with the default factory set up. Even like this you get a visible height lower in around 5-7 cms.
your ride get stiffer than stock but is worthy in handling improvement.
a few things to have in mind if you're interested in these coilovers and the website lack to tell and also there's few info about these on the internet and forums and stuff.
1. you definitely are going to need adjustable front end links. stock links are too long, unless you change the height of the coilover, but I found easier to adjust the links and let the coilover like it comes from factory.
2. Installation is not difficult despite the instructions manual is a bit confusing, but just patience and read it over and over will do the the job.
3. you're also gonna need to keep some OEM parts from you're old struts, Subimods should warn future buyers about this but is ok. gotcha cover.
front struts you're gonna need dust cover, spring insulator, spring seat and the strut mount.
rear struts you're gonna need dust cover, strut bumper, spring seat and upper mount.
so better check first before dismount anything. I just have to buy new strut mount front and rear.
I wish I could give you a more technical description of the product but my english is kinda basic.
in short words this is top notch product and worth every cent.
