Alignment Q:
How necessary is an alignment after install? If i need it, do i need all 4 wheels done? i've heard that i could simply monitor the wear and tear and make a decision from there...

Tires Q:
(In 30 mo. i will be putting the stock springs back on and returning the car) Even if i were aligned properly, should i expect to have to replace the tires before the end of the lease? I heard these low profiles are expensive.

 

get an alignment. Any change to the suspension geometry will cause the alignment to change.

If the toe is off, your tires will wear faster than camber wear.

 

so that is for all 4 wheels, regardless of rwd/awd?

 

yes, all 4 wheels are toe adjustable.

 

will do. thanks.
