E46 and DIY Negative Camber:

After much contemplation on whether to "touch" the stock suspension or not...I bit the bullet and decided to add whatever "free factory approved" negative camber I could to my bimmer. No sense in rounding off the shoulder on my brand new set of RE-01s.

Since I didn't want to remove the stock shocks to get at the strut hats, I took a dremel and a small punch to the stock alignment pins and shoved my shock towers in a WHOLE.....4mm!!! Not that I DIDN'T know the amount of camber would be so minimal based on how much room there was to move the strut...but what the heck...

Based on some geometry, the 4mm would gain me about...say... POINT 4 degrees (0.4 degrees) of negative camber...Whooopppiiiieee!!!!!

tan@ = 4mm/(21in x 25.4mm)

Therefore: tan@ = 0.0075

tan @ 0.25 = .0044 <--more than .25 degrees

tan @ 0.50 = .0087 <--little less than .5 degrees

tan @ 0.75 = .0130

tan @ 1.00 = .0175

tan @ 1.25 = .0218

tan @ 1.50 = .0262

Oh well.....any little bit helps as I definitely don't want my new rubber to end up looking like this...although...truthfully...better driving (ie. NO PLOWING) would have helped in avoiding my old tires getting this bad...
