    Got whole RTR package

    Absolutely great experience - got all the parts for Soec 1 package- and love it! Already received many compliments on new look of 20 GT convertible. Handles well and has a meaner look. New wheels are perfect too. Staff could not have been nicer and their shop is spotless!

    I Love the Rockers!

    The rockers were delivered in less than 2 weeks. The packaging was great and so was the product. It’s easy to install as long as you read the instructions or watch a YouTube video. I recommend grassroots self-service garage or the RTR official videos for reference. They look amazing on my car and fit nicely. I ordered them because I had damaged my original pair and I’m satisfied with the product.
