A drop with 1.1-2.0-inch Pontiac Firebird lowering springs is definitely going to be more noticeable than a milder 0.1-1.0-inch drop, and will help drop down your center of gravity for better handling. At this range, you’re usually still fine to run your factory shocks, although we really do recommend looking into lowered performance shocks to get the most out of your suspension since your shocks will likely be a the lower end of their travel. If going this route, you can often get an even greater deal by checking out our selection of matched spring/shock packages. It’s also worth noting that, although the drop is not extreme, you may need an alignment/camber kit for the front and/or rear to correct any alignment issues.
