Hunter alignment after lowering? When....

So I'm quite sure I'm going to stick eibachs on the car.

This sat I'm having some new rear tires on and thought I'd get her hunter aligned as the shop has all the gear but also wanted them to fit the springs. Read some reviews about people lowering first and then doing the alignment a few hundred miles after. But why is this? Would I be wrong to lower and align all in one fell swoop?

Cheers
Jamie
 
This was my experience too, even when replacing broken springs with OEM - the guy was unable to perfect the alignment until the springs bedded in for around 2 weeks or so (can't remember whether it was castor or camber he couldn't get right until springs were bedded in). Took it again after a few weeks, fixed.
 
I had an alignment done just a few days after having my springs fitted. Guy at the garage said it wasn't necessary to wait so long... Though mine were second hand springs. Doesn't seem to have done any harm.
 
Def need to let then settle... After fitting mine the ride height dropped a few mm within a few weeks.

Be sure to check wheel alignment post install and settle to prevent misaligned wheels from causing premature tyre wear.

OK - so install, give it a few weeks and then allign - cool :thumbsup:
 
Hooke's Law states that the extension or compression of a spring is proportional to the load applied, therefore a suspension spring (if it's correct for your vehicle) shouldn't alter in dimensions after being installed on a car. You should be fine to align as soon as the fitting of the suspension has been drive tested to check that it's been installed correctly with no rattles etc.

Now we are talking - facts and physics - cheers!
 
Interestingly 'mu' Hunter shop offer a free check 14 to 30 days after adjustment to make sure everything is correct.

My view is that while the springs themselves won't move all the rubber bushes and mounts do settle to their new position. That's one reason why we check torques after a few hundred miles.

The springs themselves should not "settle" if they are properly hardened. There may be a small change in ride height if new rubber top hats are used on the top and bottom of springs (as in the OEM fitting), but it probably is in-consequential. You can always measure from the bottom of the wheel rim to the wheel arch with a tape measure and recheck after a few weeks to see if the dimension has changed.
