Ref the suspension on Paul J's lovely ARP4, although Paul is keeping this quiet, as we asked him to when we did the work - early in Paul's ownership SSL fitted a shorter stiffer and progressive rebound spring at the front to remove the stiffening effect of a compressed rebound spring at static ride height to thus improve the front ride and grip, then later SSL provided Paul with a progressive spring stack at the rear (from the SSL 5L) to give a better ride yet still be able to carry increased load when required.
More recently SSL have provided similar suspension improvements to more ARP4s and 3.7 Roadsters with the factory five link to improve their ride and handling.
Cheers Peter. (declaring as a SSL director).
