These aren't just any springs and retainers; they’re precision-matched sets designed specifically for those of us who take our driving seriously. I’ve used these kits myself, and let me tell you, they deliver on performance, quality, and value without breaking the bank.
Now, let’s get into the nitty-gritty. These are dual springs, which means you're getting a setup that can handle the demands of high-performance driving. The press seat is rated at [email protected], ensuring that the springs are firm enough to keep everything in check while you’re pushing your engine to its limits. The part numbers are pretty straightforward too—SPR-100-BRZ for the springs and RET-H1000-BRZ for the retainers. Plus, you’ve got the seat locator (SEAT-H1002-BRZ) to make installation a breeze.
When it comes to dimensions, the outer spring diameter is 30.20mm, and the inner spring diameter is 22.20mm, which is perfect for fitting snugly in your engine. The springs also have a solid open pressure of 212@10mm and a coil bind of 18.50mm, giving you a max lift of 15mm. The rate is 12.50mm, which means they’re tuned just right for performance without sacrificing reliability.
These kits fit a few awesome models, including the Scion FRS from 2013 to 2016, the Subaru BRZ from 2013 to 2017, and the Toyota GT-86 through 2021. So if you’ve got one of those beauties, you’re in luck. Overall, if you’re looking to boost your engine’s performance and reliability, the Supertech Spring and Retainer kit is a solid choice.
