This! The BMW 1er and 2er really don't come with enough front camber, even for street use. My car only came with 0.5 deg of front camber, ridiculous for a performance RWD car. That is one of the big reasons why these cars understeer so badly. With the addition of camber plates and M3 front control arms I am now at -2.2 degrees in the front and front tire wear is much better, also got rid of a lot of the factory designed understeer. Also going to a 245 in the front helped.
Few years ago, outside edge of the tires were completely worn out on my SI after two track days due to lack of camber in the front. Lesson learned the hard way. It comes with 0 degree in the front, -1.5 in the rear, 61:39 weight ratio and cambers are not adjustable without aftermarket parts. It is the worst alignment combo for a fwd car for spirited driving. I guess car manufacturers don't want average drivers to get oversteer, no matter if it is fwd or rwd. The reason is, understeering is more forgiving and requires less driving skills if you make a mistake.
CSX is my daily driver but it still bothers me to drive with 0 camber in the front. That's why I bought front camber bolts, and now I have -1.6F / -1.4R camber for daily driving, and I put 9th gen 2014 SI rear sway bar (20 mm) to get more oversteer. OE rear sway bar is 11 mm. Car feels like it has more grip and it is way more balanced now.
Agreed My Civic is my winter/track car. I put KW coilovers in and STILL run a set of factory camber bolts in the summer. I am around -2.5 in the front with those mods. Then just loosen the camber bolts and pull the struts back out for the winter, run about -1.0.
