"I'm looking into upgrading my shocks and springs. Which is better: upgraded shocks and lowering springs or a full coilover system? Is one more suited for street driving?"

There really is no wrong upgrade. Often times, people simply choose to upgrade their shocks and leave the OE springs in place while others go full out and get fully adjustable coilover systems. When choosing to upgrade your suspension I believe you need to set your goals/expectations and then choose the correct suspension upgrade package based off your goals/expectations. To help determine your goal, I believe it is necessary to ask yourself some important questions first.

These are examples of questions you should ask yourself:

  • Do I want my car to have similar ride quality?
  • Do I want my car to handle better or do I want to make it feel more planted over stock?
  • Do I want the ability to choose and select my ride preferences?

In regards to which option is better; there is no clear cut answer as this is all very personal. My first question to anyone looking to upgrade their suspension is do you want a maintenance free system? Shock and spring combinations are usually an install and forget about it solution. Coilovers, on the other hand require occasional maintenance (cleaning and lubricating threads) as well as a bunch of set up time to dial in the ideal ride height (and damping if applicable). If you are someone who doesn't like to tinker with their car too much, coilovers may not be the best option. On the other hand, if you are someone who spends their free time under their car, coilovers may be for you.

In terms of ride quality, I don't believe one is better than the other. Ride quality is determined by your personal preferences as well as what you install in your car. For one, there is a misconception that coilovers will automatically make your car ride harsh. There are many coilovers on the market which are designed and intended for street use. Typically, these coilovers have lower spring rates and shocks which are valved to be more comfortable. One the other hand there are springs and shocks which are more suited towards track use. When choosing springs/shocks or coilovers you need to be aware of the shock valving as well as the spring rates. These ultimately will determine ride quality.

My personal preference to all the information above is coilovers with damping adjustment. I like being able to select my ride height, front camber, and damping. I used to have a conventional cup kit but was unhappy with the performance and the visual looks. If I decide to upgrade another car in the future I will choose a coilover system again using the same approach I discussed above.
