Hey So I just picked up a pair of H&R Springs for my B8 S4, and I was wondering if anyone knows anywhere in Montreal where I could get them installed. I called a cpouple of places and they said like $400..
Also do I have to re align my car after they are installed!?

Thanks
Anthony

 

Your alignment geometry changes when lowering and raising a vehicle; whether or not you want to pay for an alignment is up to you.

That said, why are you putting a 'crappy' suspension on your awesome (and very expensive) car? Your dampers are not valved for the different spring rate and piston travel that will result from installing lowering springs. Most people think their car 'handles' better with lowering springs, but in most cases they just prefer the 'feel' of less body, and in reality the ultimate performance of the car will be lower than stock. At the minimum, some inexpensive coilovers like the Bilstein PSS are a must on a car like yours

 

+1 Don't cheap out with H&R springs (especially if you're only doing the springs) on a brand new S4. Get some decent coilovers! Your car will thank you for it.
