    Angle kit to change steering ratio?

    Since the S550 has EPSA, is an angle kit a good mod to change the steering ratio so less steering input is needed to turn the car? I understand this can limit the wheel width that can be used. Any thought? what would be pros and cons?

    Radiator & Oil cooler

    Radiator: I really can’t find a definitive answer on radiator. I plan to duct the radiator once I get the proper radiator. Im just struggling to choose which radiator.

    Best Resonators for Lowering Volume of 5.0 with Full Exhaust

    I have a 2013 5.0 with a very loud exhaust. Not quite straight piped loud, but quite loud at anything above 30% throttle.

    S550 Rear LCA bearings ..only for drag racers?

    I was told by someone that installing rear LCA Spherical bearings will introduce binding with road racing cars and they are mostly for dragracing. Any truth to this, it confused me because I don’t understand how it could be true?
