Professional racecar driver, Billy Johnson borrowed a Q500 for some laps at Palm Beach International Raceway and this is what he has to say about them.

"The Steeda Q500 was a blast to drive on track... The adjustable suspension was far from harsh and had a wide range of adjustability to dial the car in at the track. Overall it was a nice dual purpose street and track package that raised the limits of the Mustang GT."
- Billy Johnson

Customer Reviews

Unrivaled Spring Package with Upgraded Dampers
I highly, highly doubt there is a superior "non-coilover" spring package out there. The rates make total sense. The fact that they're dual rate has significantly reduced body roll on my car such that I can run softer sway bar settings for increased compliance. Additionally, with Pro-Action Adjustable dampers, these are more than tolerable on the street, even with my upgraded bushings and bearings, bracing, and lower profile tires. I am often approached by people I passed on track asking "what coilovers do you have". You'll have to spend big bucks to beat these things.

Competition dual rate springs - daily driver review
Installed these springs myself, using the supplied instructions. First impression was, they feel like stock. Then I hit the highway and damn these make the car feel tight, planted and secure, cornering is way more flat. Highly recommend these springs. Alignment was easy to dial in, as the drop was 0.75-0.9 inch all around. Car doesn't bottom out on any speed bumps. IMHO perfect height.
