I have Konis and coilovers on my TII with Eibach springs, not sure of the spring rate or length. My rear will bottom out on dips and bumps, regardless of the dampening setting. Do I need to A) raise ride height B) get a stiffer spring C) get a longer spring ??? Thanks.

First make sure you are really bottoming out. You can put a nylon cable tie on the shock shaft to see how far up it gets pushed. Raise the ride height second, if that won't screw things up from how you like it. Next try stiffer springs. Longer won't help if the spring rate is the same. Stiffer springs in the rear will change the balance of the car, and make it more prone to oversteer (or less prone to understeer).

It is a very abrupt and jarring THUD on whichever tire hit the bump/ dip. I'll try the zip tie thing. The car understeers out of boost and oversteers in boost. I already tried rasing the ride height 2 turns, and it did help, but it still happens. Don't want to raise much more...
