so i recently emailed raceland to inquire on how their stuff is made and this is the response i got back. pretty interesting
just thought id throw this out there might clear the air a little bit.Our
coil springs are chrome silicone wire and those are heat treated and
pre-blocked to prevent sagging. Phosphate coated to prevent rusting and
then powder coated. The springs are wound by ISRI. ISRI is the main
German coil spring supplier for the German automobile industry. Our
galvanized front struts are with self-adjusting shock absorber (gas
pressurized) and adjust themselves to your driving style.
