I need a 2.5" diameter, 2-3" length, 100-200lbs tender. The prices from Eibach are ridiculous. Any other sources? I'm ok with a China spring if it looks like it might work.

Like this, but not $500

Club roadster, pick up some raceland tender springs for free that one of them removed to get hella low. The hyperco one's cant be that expensive, they're like a $250 option on xidas and that include the spring coupler.

I love Swift springs. Rice that no one will ever see or give a **** about is the best rice.
