As long as you have the coilovers set to your desired ride height the choice is yours.
You can go for a basic track using the old fashioned metal rods and dials methods which any tyre fitted can do.
There's 4 wheel laser alignment which some tyre places can do and some specialist.
Full geo is the next step. But if it's tracking right and all 4 wheels are pointing in the right direction the step up to full geo from a regular drivers perspective isn't really going to be noticeable.
Lastly there's full geo and corner weighting which IMHO is pointless for a road car. But good pub talk
Price wise it goes from £35 to probably £250
Some people like to mess with their setup, some don't. My rule of thumb is if the tyre wear is acceptable it can't be far out.
I've had mine Geo'd once and tracked once in 14 years of ownership and my suspension has been on/off probably in excess of 20 times.
