We recommend getting a wheel alignment every other year. Bad alignment
will cause premature tire wear, and it's cheaper to do alignments than
replacing tires! Inspect tire wear religiously to see if you need
and alignment; we normally do this when filling gas, as it's easy to do a
quick walk around the vehicle to check the tires. Abnormal wear
on one side of the tire (inner or outer edge) is a sure sign the alignment
is out of spec.
We recommend these alignment spec for your street FC...
Front toe: 1/16" total toe in
Front camber: -1.0° (no more than -2.0°), per side
Front caster: stock
Rear toe: non-adjustable, but try to keep at "0" total toe
Rear camber: -0.5° (no more than -1.0°), per side
Rear caster: N/A
These alignment specs are within stock Mazda spec and will give you best
wear with best control on street driving. More aggressive alignment
specs can be dialed in with sacrifices. Front toe-out to 1/16" is better
for quicker turning response (recommended for autocross alignments) but makes
the vehicle twitchy at freeway speeds. More negative camber (in front,
up to -2.0°) can give you better cornering stability but can cause
premature inner tire edge wear on the (front) tires.
