Wheel Question

[Ralliart23]

if i buy 19 inch rims for my ralliart, (as apposed to the 18 inch stock) would this screw up my 4 wheel drive / diff / axle ratios and stuff?

If you go with 19's you will have to go with a 35 profile tire ex. 235/35R19 etc. With a 35 profile tire be prepared to feel alot more little bumps in the road and have a little rougher ride. 19's won't mess up the AWD, diffs etc as long as all 4 tires are the same size and your wheels are the same size and offset.

wont mess with the spedometre?

it will.
if you go smaller wheel speedometer will read higher mph but you'll actually be going slower.
if you go bigger wheel speedometer will read lower mph but you'll actually be going faster.
Im not too sure how that get fixed, but I think there are adjustment you can make to fix the speedometer.
