Let's talk track with Devin H w/ SPL Parts!
When converting a fully driven street car to a track car upgrading suspension components is a must. When we started our journey of driving my 15 STi to and from the track we upgraded the suspension with some small changes such as going from rubber OEM bushings to polyurethane bushings , and if you've done this before you probably instantly realized how much vibration and road noise the rubber bushings have been absorbing almost instantly (unless your car is already pretty loud). You also probably notice how much tighter the car feels around turns due to the movement being more restricted in comparison to the rubber bushings. Well, we now took it a step further and upgraded our bushings to SPL's FK spherical bearings among other full race car mode goodies.
