Available through any Ford dealership, the Steeda Q400 started at $10,595 above the cost of a stock Mustang GT.
For that, here’s what you got:
Engine: The “400” in Q400 represented the amount of horsepower the modded engine produced, although that’s really just a rough estimate — third-party dyno testing actually pegged the Q400’s output higher, with as much as 450 horses at the crankshaft. Given that the GT’s stock 4.6L V8 had been upgraded with a Vortech centrifugal supercharger, those numbers aren’t hard to believe. Other under-the-hood enhancements of the Q400 include a K&N air filter, Bosch fuel pumps and an HD aluminum radiator.
Exterior: On the outside, the Steeda Q400 is distinguished by a number of the expected upgrades, including a hood reminiscent of the Cobra R, rear spoiler, front air splitter and many other ground effects.
Other upgrades: The Q400 also sported a tuned suspension, a Borla stainless-steel exhaust, 13” Cobra front disc brakes, a short-throw shifter and a set of BF Goodwrench g-Force tires sitting on 18” Steeda Ultra-Lite rims. Because each Steeda Q400 was produced by hand, buyers were able to add other upgrades and enhancements as they saw fit. One popular addition was a Paxton Novi 2000 blower, available for an extra $1,000.
