a t We’ve already developed the Z/28
racecar quite significantly, and it’s been
surprising how much it’s changed in
what’s been a relatively short period of
development time. The Stevenson
Motorsports guys have been fully
involved in every step of that process
because they took delivery of the first car
immediately when it rolled out of the
Pratt & Miller Engineering shop and have
been there for every change.
One of the sweet things about the
racecar with the stock LS7 engine
package is that the torque curve is very,
very flat, so we’ve got a fantastic range of
torque from about 3,000rpm right up to
close to the rev limit. Given that the
Continental Tire Challenge rules mean
we’ve got fixed gearing for the GS
category, that’s very useful for a driver.
Another thing that’s really special is
the phenomenal attention to detail that’s
gone into the build. Coming from the
Rolex GT Camaro, which is obviously a
purpose-built racecar, the Z/28 was
surprisingly similar in handling and
balance to the GT car. The fact that the
GS-spec Z/28 handles so well straight out
of the box, coupled with that flat torque
curve that we’ve got from the LS7, makes
for a pretty drivable package.
Of course, it’s still quite early for us with
this car. As I speak, we’ve still yet to race it,
the Driver’s view
so the only benchmark we have is what
the previous Camaro did in the GS class.
But I can say that, in terms of initial
impressions, there’s every reason to feel
confident that the Z/28 will be a strong
and competitive package. The production
Z/28 is a superb road car and I don’t see
that changing as it’s turned into a racecar.
The driver’s seat must remain in
the same basic position as in the
production car, but passenger and
rear seats, air bags, trim panels,
center console, headliners and
inner front door panels are all
removed. The production Z/28
steering wheel is replaced by a
race-spec, flat-bottom version.
