SR20Forum Exclusive Springs To include Hypercoil (Hyperco)
Now you know the difference, here is the rest of the particulars on the SR20Forum Exclusive springs.
Hyperco Springs (Hypercoil) -
Welcome to Hyperco (Applications: B13 and B14 only)
Hypercoil is a manufacturer that specializes in racing springs and custom springs for high end tuners (Hennessy, etc.) Some of the brighter suspension minds on the forum, including Chriscar and Choaderboy2, were trying to get a spring manufactured specifically for our B13 platform. A spring that could be used with an OEM length or shortened strut. A versatile spring comfortable enough for a (firm) daily driver, stiff enough to stay off the bumpstops, affording a slight drop (1" both front and back), and good for fairly serious auto-cross or road racing (not street racing, duh.) After much trial and tribulation the Hyperco Gen II spring was born. It is a brilliant design and execution, and is the brain child of the Hyperco Engineers and our very own forum brainiacs.
Hyperco Gen II Spring rate: 110-290 front, 75-200 rear, progressive rate
Drop: 1" front and rear
Struts to use: KYB AGX's or better yet CSK's.
