Most times when independent companies modify or alter production cars it ends in tragedy. I am writing this article about one of the ones that didn't fail, Techart's new 2017 Porsche 911 GT street R, a beefed up version of the already popular car. Their new model will supposedly have around 720 horsepower, a vast improvement even over the 911 GT3. Techart has even maybe improved the looks of the car (which my co-writer may disagree with). Overall, a very good redesign.
