I know I am bumping my oldish thread, but I thought I would give a little review on what I thought of the springs/wheels so far.
Look-wise: It is perfect. I love how it sits and I think the wheels look great, gave my car totally new character. Also the new lowered look is amazing.
Feel-wise: I can definitely feel the stiffer springs, and going from stock tire size to low profiled 19s obviously is going to give a little rougher ride. I would say I was not expecting it to be THIS different, but I am still fine with it as in general it is still great, but on bumps you can definitely feel them probably 2-3 times more than with stock setup.
Additional Comments: This is more of a question rather than a comment, but ever since I put on the new wheels/tires and springs - my steering wheel has a very slight whine and/or friction feeling to it in a few spots when turning, it seems to be @ about a very wide angled turn or when switching lanes, it sounds like it comes from the actual steering wheel. I am going to set it up on stands this weekend and to some testing with the wheels in the air, but did anyone else get a steering wheel noise with the lowered car?
Overall: If you're willing to sacrifice some ride quality to gain visual quality, I say new springs and wheels are a definite must. I am re-in love-love with my LS, I already loved it, now I love it even more. I cannot wait to get the new bumper and hood on and get this thing cleaned up!
Thanks for reading if you did; and any comments about the steering wheel would be appreciated.
