4 Things You Should Look for When Buying Coilovers

You’ve finally decided to buy coilovers for your car. That’s great! However, if you’ve checked out all of the lowering mods above and you still have no idea what to look out for when buying coilovers, we’re here to help you. 

1. Damper design

It’s the epic rivalry of the twin-tube and monotube dampers again. Twin-tube dampers specialize in providing more suspension stroke and better ride quality. On the other hand, Monotube dampers deal with heat dissipation better, and therefore dramatically improves the responsiveness of your damper. In a nutshell, if you’re looking for performance-oriented coilovers for aggressive driving on the street and track, pick monotube. Otherwise, if you just want better handling that doesn’t cost as much, pick twin-tubes.

2. Spring Rates

The higher the spring rate is, the stiffer the springs would be. By getting the right coilovers with the proper spring rate, you’ll be able to effectively reduce your car’s body roll and make its handling more predictable. Before you pick a coilover, determine first what application you will be using: street driving, drag racing, autocross, etc.

3. Spring and Valve Adjustability

Aside from fixing their vehicle’s handling, coilovers are usually bought because they’re capable of lowering a car’s ride height effectively. Having easy and convenient adjustability for the ride height, damping, and spring preload is necessary when picking the right coilovers.

4. Top Mounts

Manufacturers usually use rubber bushings for their OEM parts because it deflects more and is typically the cause of suspension precision failure. On the other hand, Pillow ball bushings are static; it doesn’t move, which makes it better in providing a more precise feel when the suspension and steering are in action.

There’s a lot of options you can choose from if you want to lower your Toyota MK3 Supra. With the abundance of aftermarket parts manufacturers and a bustling Supra community, you’ll be having a great time looking for some lowering mods for your third-generation Supra. If you’re budget-restricted, you can opt for eBay coilovers. However, if you want a decent set of coilovers and you’re prepared to spend a bit more to get them, then there are a lot of mid-range lowering mods you can choose from.
