I just installed the 22 mm rear sway bar from NM Engineering and have to say it really performs like expected and advertised. It has high quality mounting brackets and has significantly reduced the understeer found in the stock Mini.
Fantastic Customer Service from Aaron!! He is always helpful when I make a purchase and especially when I have a question and make a phone call, he's always helpful to answer my questions about an item or a purchase I've made. Very knowledgeable. Highly recommend OUTMOTORING!!
