Yeah I didnt get the pillow ball mounts, instead they work with the ones that come with the car. I was just being cheap. (if you can be dropping 1k into coilovers). As for the settings I am undecided whether i want to cut holes into the rear interrior to make adjusting the rears easier. It is definately NOT worth it to take the entire damn thing out and wrestle with the rear strut tower bar just to make a one or two click adjustment. Right now i have the rears set at 4 and the fronts at 8. (out of 16 with 1 being the stiffest) The rears really didnt seem to make that much noticable difference in ride quality though the handling likes the stiffer settings by a noticable difference. It makes the car much more nutral on turn in. On hard higherspeed you turns the rear now comes out before the front. (also have TRD
sway bars and rear strut tower) I havnt played much with the front yet, mainly because i was trying to figure out the rear before i put the interior back in. On that note, less weight is nice... BUT NOwhere near as nice as it is to have MUCH less road noise. I am a person who doesnt use stereos or such much in a car cause I like the sound of the engine. I usually dont care about such things, BUT... without the rear interior you hear every peble and grain of sand you go across rattle through your undercarriage. It feels like you chopped off the back of your car. If you really want less weight take out your rear seat backs (really easy) and the shelf but unless you are super hard core, leave your interior in. You will love driving much more.
