not much different from S4 to S5, all the suspension is interchangable between the 2nd gens. i'm not sure about 15 to 20 degrees but they are little more aggresive than other cars i've worked on, the S4 and S5 suspensions are is very ahead of its time. Plus mazda's main goal was to enhance suspension techniques for the RX7. What other car out there, you gonna find 50/50 weight ratio distribution.
