One of the questions we get asked most often is how to strengthen rear suspension. There are a few different ways to do this, and the method you choose will depend on your budget and what you're looking to achieve.
If you're on a tight budget, one of the easiest ways to stiffen up your rear suspension is by adding an aftermarket antisway bar. Antisway bars work by connecting the left and right sides of your suspension together, which helps reduce body roll and keeps the car more level during cornering. They're relatively inexpensive and easy to install, so they're a great option if you're looking for a quick fix.
If you have a bit more money to spend, another option is to upgrade your shocks or struts. Shocks and struts play a big role in how well your car handles, so upgrading to better quality components can make a big difference. If you live in an area with rough roads, upgrading to thicker walled shocks can also help improve ride quality.
Finally, if you want the best possible handling from your car, investing in coilovers is the way to go. Coilovers allow you to adjust spring rate and ride height independently, giving you complete control over how your car feels on the road. They're not cheap, but they offer the best possible performance for serious enthusiasts.
