Through trial and error, I found that the BBK upper control has significantly improved my Mustang's handling. The improvement is impressive and noticeable, especially during cornering. Installing this product was a breeze and DIDN'T take long at all. The only drawback is that it`s a bit pricey, but you get what you pay for in terms of quality and performance .Overall, i would highly recommend this product to anyone looking to upgrade their suspension system..
