4mm further than this set up will be very aggressive. Depending how low you decide to go the car will camber in enough for you to tuck, but a stretched tire will for sure be in order. If you drop just a tad more than where you are now, you will for sure have to use camber arms to add more camber. I'm running 20x10.5 E25 in the front with 255/30's and I'm an inch higher than Natalie's ride height and I rub occasionally on the outside part of the tire. Not a big deal to me. Lowerd lifestyle, lol. Hope that helps. 19x9 E25 will look wicked slammed. Can't wait to see the finished product.

 

Here is my car when I tried to run standard size tires. The front fit pretty good 245/40/19x9 +25 and -1.5 camber rubbing the outside of the fenders on inclines when turning the wheel all the way (probably wouldn't be an issue if your set higher). The rear rubbed like hail even at -4 camber 275/35/19x10 +25. I ended up moving the 245/40 to the rear and getting 225/45 for the front.

 

awesome thank you both so much!

definitely helped
