By trial and error, I am establishing the spring raters I need for my front coilovers. As the springs once fitted, are sold, then I an trying to limit the error element of this by getting some feedback. For anyone with adjustable coilovers on their E9, then I would presume that the length and width of these are different from stock. Can you give me some feedback on diameter, length and rating and whether you are happy with the set up. Mine are Gaz Gold coilovers which utilise a 2.5" internal diameter. They are 9 inches long, but are currently too weak and coilbound over more extreme bumps in the road. As I live in a city known for its more extreme bumps in the road this is not acceptable in the long run. Any help is very gratefully received.
