Would I notice my car running better if I went back to oem coils? When I bought the car they were already installed (which was over 2 years ago) so it wouldn't hurt my wallet to throw oems back in. I Can also buy a brand new sct x4 7015 tuner for $300 is that a good tuner and is it worth spending . Sorry for the million questions lol Thank u guys again
Do you have caster camber plates up front? I would assume whoever lowered it installed them too but you never know... if not you should add them. You can tell what kind of gears you have by rotating the tires and counting how many times the driveshaft rotates. Jack the car up and spin them, if it rotates 4 times you have 4.10s, 3 and 1/2 times you have 3.55s, 3 and 3/4 times you have 3.73s etc...
You should definitely add lower control arms, Steeda makes some real good ones. As far as your coils, if it is running fine now then don't worry about it but if you ever do have to replace the coils, get OEMs. The SCT x4 is actually a top of the line tuner so yeah it is good to get. You will need to buy the tunes too. Steeda/Bama do free tunes for life and if all you need is a canned tune then they are ok. I'd recommend an actual datalogging tuner though... one member on here recently almost lost a motor on a Bama tune but he road races the car on actual courses at extended high RPMs.
