What is the front and rear spring rate of these please?
sorry, that I dont know, but here is all the spec I found:
# Multiple spring rate combinations available (see Option Box on right for choices) to suit various driving styles and applications
# Dampers have undergone numerous shock dyno tests to determine ideal valving for each application, delivering superb damping characteristics.
# 8 levels of rebound adjustable damping to suit a variety of road and track conditions.
# Patent-pending adjustment mechanism ensures clearly seperated damping levels marked by an identifiable click at each setting, making for easily repeatable settings every time. Needle-valve design ensures no internal damage due to over-turning of the adjustment mechanism.
# Fully Independent height & preload adjustments.
# 3 stage anodized coating on shock body provides extra weatherproofing and protection against oxidation.
# Viton sealed pistons protect vital moving parts against friction and wear, even against extremely high temperatures and oil.
# Nitrogen gas-filled lower portion, with free-floating secondary valve offers more flexible low and high speed damping.
# 46mm piston diameter and 54mm shock body provide improved damping capabilities and heat dissipation. 89-91 Civic: 42mm rear piston/50mm rear shock body
# Two 6061-T6 aluminum alloy collars hold spring and lower mount in place and an additional third collar provides added support to the spring perch.
# 6061-T6 aluminum alloy is used for both top and bottom mounts, coated in a fade and chip-resistant paint.
89-91 Civic: Uses modified, raised topmounts combined with shortened lower mounts in the fronts to achieve a large range of height adjustment, while retaining shock travel.
# 240 hours of salt spray test on steel shock body shows no signs of fading or rust.
