I'm from a company here in Australia (King Springs Pty Ltd) who have developed an extensive range of coil spring products to cater for just about all types of suspension preferences for the GTO's. We have developed tapered wire progressive rate coils for both front & rear with various rates from comfort through to performance applications.
We are heavily involved in the motorsport scene here in Australia, working closely with many of the leading V8 Supercar teams.
The Australian equivalent of the GTO is the Holden GTS, & CV8 Monaro and King Springs has both distributed and installed coil springs in a great number of these vehicles, offering varying heights and spring rates.
We have also introduced a lowered 1” Part No. KHFL-47HHD which is a new ‘double end tapered’ design specially manufactured for top end performance. This design has a spring rate of 350lb” at the first inch, increasing to 500lb” at the second inch from vehicle ride height.
The above coils are complimented by two new Part No’s KHRL-45HHD & KHRL-46HHD (refer Sept. newsletter) in the rear giving similar top end performance with the height options giving a level (46HHD) or slightly raised rear look(45HHD). These coils are a tapered wire design with a spring rate of 600/1000lb”
