So I chopped off the old endlinks completely and installed some beefier ones then went on a driving impression of the new MS bar. I been driving around with it disconnected and the rear whiteline bar connected and hated every second of it. I read somewhere that disconnecting the front was better and beneficial but the car felt like garbage. There was a bit more roll (obviously) but not a ton like you would think because my coilovers have high spring rates on the front and back, the tires would roll over a bit more in the back and the car would not turn if you gave it alot of gas or turned the wheel really quick in one direction. . Not fun when your car has never done that and you dont expect it. I almost ran into a curb. With the GS front bar the tires would chirp a bit in the back and if you were going fast enough or the turn was sharp enough the back would suddenly kick out so I never really went that fast then turned extra sharp. If I tried E brake slides would be really easy but I dont beat on my baby like that so we will never know lol. At low to mid speeds and a sharp turn the rear tires would just chirp and the fronts would under steer a bit. Does that happen to anyone else with Ksports, a gs front, and a whiteline rear bar?Anyway my impression of the front was really good. The back end didnt kick out but both F and R would grip fairly good until they both slid out (could of been dirt on the roads this was a street impression). Also a very weird feeling but I was going pretty fast. I could also blame my tires on that one. If I have a little bit stickier ones or I was on a clean track I could go even faster I bet which is crazy. Turn in was crazy better (for lack of a better description) At any speed I turn the wheel and the car went with 0 roll and zero chirp of the rear. I will say the whole hit a bump on one side and the other feels it thing is more noticeable now. But im not to concerned with that because the car is a bumpy ride any way. I want to go really test this set up out at willow springs if I have enough money for Mazfest in august this year but im not sure I will
I also threw on some extra mazdaspeed stickers on I had in the closet for years collecting dust so anyone around when I have the wheel off knows whats up (which is more often then you would expect) So far ill give mazdaspeed 2 thumbs up on the 25mm front and 22mm rear decision. A recommended upgrade for anyone who can find one
