Coilovers are a type of suspension that allows for adjustability in both ride height and spring stiffness. When it comes to choosing the right coilovers for your car, there are several things you'll need to take into account.
First, consider what type of driving you'll be doing most often. If you're mostly going to be on the street, then you'll want a softer spring rate so as not to compromise comfort. However, if you're planning on hitting the track more often, then a stiffer spring rate will be necessary in order to provide better handling and performance.
Next, take a look at your budget. Coilovers can range in price from around $500 all the way up to $2000 or more. Obviously, the more expensive options will offer better quality and performance, but if you're just starting out it's not necessary to break the bank. You can always upgrade later on down the road as your needs change.
Finally, make sure to do your research before making any decisions. Read online reviews, talk to other drivers who have experience with coilovers, and get an idea of what will work best for your specific vehicle before pulling the trigger on a purchase.
