A new member of this brand, my prior computer was a respectable model called the PC5, and it never failed me while it was being used. Now, just in case it was required, I made the decision to go to the PC6 kit. At first, it seemed as though the car was getting softer and more capable of absorbing the road's imperfections. Drainage is unrivaled in terms of importance on wet roads. If you are unsure about the option, my recommendation is that you make the purchase.
