Your chassis wants coilovers. The only question is which spring rate.
Your E46 came with struts an accountant signed off on. Your S13 was set up to survive the test track, not stick a corner at Sonoma. Coilovers are the receipt you write the factory for under-delivering on your chassis.
A coilover is a spring and damper on one adjustable body. You dial in ride height, spring rate, and compression — then you drive the chassis the factory would have sold you if the accountants hadn’t won.
Ride height you set yourself — not what the factory thought was “sporty.”
Rebound, compression, preload. Turn a wrench, change the car.
Set corner weights once. Stop rolling into apexes on three wheels.
Spring rates spec’d for E46, FK8, S13, C6, BRZ — not a generic 1000-SKU list.
Chassis code, submodel year, top-mount style, spring rate for your curb weight, and adjustable range for your target drop. If you need camber plates or endlinks for the kit to work, we flag it on the order before you pay.
No threshold, no fine print.

Call 813-535-5801 or email sales@threepiece.us. Tell us your chassis, your daily-vs-track split, and what you want the car to do. We’ll quote the right rate.
Depends on the rate. A KW V1 or Bilstein B14 daily-drives fine on 80% of modern chassis. A race-spec Cusco on 12K front / 10K rear is not that, and we’ll tell you before you buy.
Yes — Fabtech, FOX, and Ridetech for F150, Tacoma, Silverado, Wrangler, and classic American iron. Those aren’t featured on this page, but they’re in the full coilovers catalog.
New ride height changes sidewall load and contact patch. If you’re dialing in stance, it’s the right moment to look at tires and wheel accessories at the same time.
Chassis code, top-mount style, spring rate, and adjustable range — we check the kit matches your car before it leaves the warehouse.
