For the first time in a while I recently had passengers in the car. The tires were rubbing badly (not sure at this point if front, rear or both) They do not rub at all with just me in the car, and I have driven all over the place in a variety of conditions. My setup is as follows:
•2006 base with auto trans
•Koni SP3 shocks with Tein S-Tech springs, camber adjusted as close to factory spec as possible but no camber kits, toe at zero
•18x8 +35 w/ 245/40 front and 18x9.5 +45 w/ 275/35 rear

I am reasonably sure my shocks are fine, so I figure either I am too low, my springs are too soft or my wheel/tire fitment is just too aggressive. I is amazing to me how much further my car sits down when people get in. What would the most likely cause be? Thanks.

weight pushes down on the shocks and springs.

I would hardly call your setup aggressive. The offsets are very high and the wheel widths are not that wide. Well the 9.5 is somewhat wide, but the high offset doesn't make it aggressive. Besides the added weight in the car from people being in it, the tires you have are way too wide. I can tell you don't want a stretched setup by choosing the tire widths you did, but they are pretty excessive and aren't helping your situation. If you want to keep those wide tires on the car, you are going to have to roll the fenders OR put skinnier tires on OR a combo of both.

Assuming you want a meatier tire and no stretch, but skinny enough not to rub:
For a 18x8 rim I would run a 235 tire
For a 18x9.5 rim I would run a 255 tire

Hope that helps.

275 on a 9.5 is overkill on a FWD car

Bump the width down to a 255 like The Machine said and if that doesn't help, add a degree of camber in the rear. Also, take out any extra stuff you have the in the trunk.

275 on 9.5 @ factory spec is aggressive. It is a combination of the latter two choices if you think about it, but I agree that a smaller tire size is needed.

i THINK your spring isn't strong enough to compensate for the shorter length, as are most if not all aftermarket lowering springs.
