TEXT_OF_5_STARS Posted on 10/17/2011 by Patrick Van Osta
"The entire team has been great. My car was the donor vehicle for Vivid's new 997 Carrera turbo kit, so I expected growing pains and bugs galore. Instead, the entire experience has been almost completely painless. At every turn, Dan and the team were there to help me out or point me to resources local to me in SoCa. I am a very happy customer and my car is absolutely transformed."

"Love the look. Austin recommended these and they came out great. Super clean. I'm posting a pic as soon as my calipers are done. Brakes work great. Very smooth and I drive alot of miles. They got to me fast and I loved that Austin was very straight up. Let me know what was necessary and what wasn't. I'd recommend these guys wherever you're located. I'm in Cali and they are in AZ. Keep up the good work fellas."
