Your Oem wheels have a tire pressure sensor on the Oem rims once you change it that light will stay on there is no way to get rid of it unless you go back to stock.
Good luck

im wondering what camber kit to go with that's inexpensive? i have the eibach springs 1.1 front and 1.0 rear with 2753520's on thruxton 10's rear and 2453520's on front
also i think if i correct the negative camber in the rear that i will have to get the fenders rolled would running a 2853020 make this worse? any help would be great or comments on what would look better? here is a snap

i dont think you should change the tire size 275 is wide enough with the cars hight droped you already have negative camber @ the back. you can get that check at you alighnment shop. anything more then -1.5 degree will eat up the inner side of the tire. If you not into track days or high speed corners dont get it.

The car seems fine to me.

After the car has 20" wheels its sitting lower then stock. You need to get a camber kit if your car is -1.5 camber , my car right now is sitting@ -- 1.3
Which is not so bad if anymore then that then I would sugest a camber kit.

Check the camber @ an alinment shop see what u get. If you need better handeling just change the sway bars will help a lot don't spend to much unless you track the car

^What was your wheel and tire setup prior and what is it now? you may have been running a taller than normal tire or a smaller than normal tire now. 20's will appear to fill the fender arches more but if you ran the correct tire sizes given your wheel diameter you shouldn't have that much of a difference

I don't think a generalized statement of putting 20" rims on your car makes your car look lower.. You have to measure the tires and rims prior to putting them on.. If they're the same total diameter as your previous wheel/tire setup, you won't notice a difference.

For example my stock 18s were 225/45/18 front and 245/45/18 rear

my 20s setup is 245/35/20 front and 285/30/20 rear..

Because the sidewall of the tire is smaller (middle number) then you are compensating for a larger wheel diameter.

Based on your description, I'm guessing you have larger tires than you should for a 20" rim. You are probably still rolling on 40 or 45 sidewalled tires. (not a good idea) you're going to not only be rubbing which will cause you to burn through your tires prematurely, but your spedometer is also not accurate.

FAIL. This means you purchased too small of tires for your 20's. The height of the wheel from the top to the bottom should come near if not the exact height which would keep the height of your car the same.

Also, getting larger wheels does NOT cause your car to "look lower". If anything, getting larger wheels makes it look "higher". It draws more attention to the wheel gaps which causes it to give it the 4x4 look that is dreaded.
