For starters, I didn't know that you could still do the 'free adjustment' with the plates installed... do you know if that's the case with an '05 (no air suspension, of course) as well? If so, and I decide to do it, I guess I should wait to time it with a new alignment...
By the way, do you think the X5 would handle better with 295/40-20s all around than with 275/40-20s in front, and 315/35-20s in the rear? If so, any drawbacks? |
295's all around would depend on the rim width also... technically you are removing some understeer with the square setup.. i'm guessing because i don't know what the offsets are, but your front track should now be wider then the rear.
but i don't know how wide your rims are... which affects how your tires sit on the rims ( straight up and down, slanted out, slanted in). that affects how they perform too...
with bigger tires, you also add on more weight... general rule of thumb: every 10 lbs of unsprung weight = 1 whp regained...
also the cost of the bigger tires is more so with the -4 degrees of camber on the rear, you are wearing out the tire pretty quick as it is...
