This thread was very helpful for me so I will share my Configuration.
Wheels - Varrstoen ES6
Offsets - R: 19x11 +20 (5mm spacer), F: 19x9.5 +22
Tires - Falkon 452 - 305/35/19 | 265/30/19
Suspension - BC BR Coil over setup. Lowered approximately 1.4" all around.
Camber settings - Adjusted to stock rear ony @1.8 Degree and 1.9 up front.
Fenders scrape a bit up front on larger bumps, any lower would be asking for trouble. No rolls. I had to raise the car .2" up front because of aggressive scraping inside the wheel wheels and bottoming out the front end, I'd recommend a stretch tire if your planning on going lower than 1.3".
