"All I have to say is 'Holy Cow!' You have made my '66 Mustang feel like I can actually drive it and have fun. Instead of squeezing my butt cheeks together and praying to make every turn without plowing into the wall, I am taking the turns faster and faster with the utmost confidence. To think that only the rear end has the GR 350 suspension (Watt's link, controller arms, Severe-duty torque arm, Koni adjustable coil overs) and made this much of a difference I cannot wait for the front suspension to be done. The rear suspension has made my current front end work and even made one of my passengers at Laguna Seca go 'Holy S**t, what a difference.'
Thank you John and everybody at Grigg's Racing for making my car an absolute blast to drive.
