Evan Smith Track Tests Steeda’s 686 rwhp 2015 Mustang GT

July 31, 2015 9:40 pm

Evan Smith said it himself, “This Mustang eats up the track and leaves you plenty of performance for the street.”

The team at Steeda Autosports has been hard at work developing new parts for the S550 platform and we’ve turned our Triple Yellow Q650 2015 Mustang GT into a corner-carving track monster. Pumping out 686 rwhp on 10 psi and pump gas, it’s a force to be reckoned with both on and off the track.


“Our objective with the Q650 and our Q-series of Mustangs is to build a track-ready car that outperforms much more expensive cars for far less money,” said Dario Orlando. “We manufacture and sell our own parts so you can purchase a complete car with the Steeda package installed, or add the parts to your existing Mustang. For the 2015, we first built a mockup of the front and rear suspensions. This allowed us to analyze the suspension arrangement and note the areas of concern as they relate to high performance. We’re looking to satisfy the performance-minded enthusiasts who wants a fast, capable street car that is ready for the track.”


With a mix of straights and corners, Sebring International Raceway seemed like the perfect place to really put our Q650 to the test. Check out our full build list and a link to the complete write-up below:
