I purchased the Apikol Rear Differential Mount for my S4. According to Apikol “This performance rear differential mount will provide a precise and direct feel to dramatically enhance your overall driving experience.”
I don’t believe it is a bad product for replacing the stock rear differential component to improve longevity, but the feel with the Apikol product was unchanged.
