@RevNev do you have any experience with TEIN coilovers , if so how would you rate them. I bought mine without really looking into suspension when i bought them simply because i found it a bit overwhelming with all the information out there. There are setup stiff , but in the wagon it seems to hold it a bit flatter but i feal they do need a bit of a tune, particularly on concrete highway roads at low speeds (bumper to bumper ) traffic it develops a bit of a bounce
No, I've only used KW coil overs on a couple of track cars and Bilstein on a VE Improved Production race car that Supashock modified. On road cars, I prefer the King spring Monroe fitment as the appeal of coil overs for most, is the height adjustment more so than shock performance and function.
What you're describing with the Tein coil overs, is too much spring rate for the shock dampening. Shock valving or adjustment should match a spring rate and if the car is uncomfortably stiff, it needs softer springs and the shocks adjusted to suit best done on a shock dyno. Many soften the shock adjustment for the car to feel more comfortable but then the shock is too soft and can't control the spring.
Ideally, adjustable shock dampening enables you to use different spring rates and retain the same shock without need to re-valve it. Electronic shocks that are switch adjustable use a lot of compression dampening and softer springs for comfort and performance settings. It's ok on a road car but when compression dampening of the shock helps stiffen spring rate, the car will lay over on long corners and doesn't work well on a racetrack.
