If you’re considering lowering your ride more than two inches, you are definitely approaching “slammed” territory. You’ll definitely want to check out some aftermarket performance shocks to maintain adequate suspension travel with Pontiac Vibe lowering springs since most factory shocks will likely be very close to bottoming out at this point. That being said, your ride will definitely look awesome! With the right shocks and front and rear alignment/camber kits, your ride should also handle really well.
