RM11 Formula 1000
2011 RM-11 Is Here!
The Speads RM11 is a single seater formula race car designed to compete
in SCCA F-1000 and accommodate a variety of motorcycle engines. The Speads boasts the first
Formula One style body in the world for this class of racing, and new for 2011 is an updated wing package
designed by noted aerodynamicist Alain Clarinval.
The RM11 is sold as a roller complete with radiator - plug in your choice of engine and go racing! Alternatively,
RM11's can be purchased turn-key, ready-to-race by our central distributor, Rilltech Racing.

The outstanding tubular chassis is one of the highlights of the RM11, as with our previous RM models.
The chassis is a lightweight space frame which has been developed over the last six years in testing and racing
in the USA, United Kingdom, and South Africa. Chassis members are mild steel tubing of mainly 1.25 inch
diameter x .095 inch wall thickness. The car easily meets the 1000 pound weight limit for Formula 1000, even
with 200#+ drivers.
Main and dash roll bars are 1.5 inch diameter x .83 inch wall thickness. TIG process is used for welding.
Additional sections are used in high stress areas, such as diff, engine and suspension mounts. Chassis rig testing
with the RM11 has led to more frame stiffness than ever, which we believe to be best-in-class.
This excellent chassis means not only excellent handling, but easier repair. High strength means you won't have
to straighten the chassis after off-track excursions, and side impact protection means you are safe in your car.
This also translates to the outstanding mechanical grip that the Speads is well known for, and also reduced tire
enabling the Speads to use softer tire compounds relative to the competition.
New for the RM11 are dual, cockpit-adjustable front and rear anti-roll bars. By adding
anti-roll bars, this allows use of softer springs, increasing mechanical grip even further over previous generation
The RM11's cockpit is quite roomy, as we've designed it to accommodate larger drivers. Drivers up to about 6'5" and
around 250# should have no difficulty comfortably fitting in the RM11.
Approximately 50 rod ends are used per car, ranging from .415 inch to .5 inch. Not only can toe and
camber be adjusted easily, but caster can be altered in a matter of seconds. Control arms are fabricated
from aero tubing of .06 inch wall thickness, and include anti-intrusion beams for added safety. Other important
components such as steering rack and front bulkhead are die castings.
Pushrod suspension is used at all four corners. Left hand threads are utilized where quick adjustment is
needed such as pushrods for ride height adjustments. Centerlock wheels are standard. Uprights can be installed
on any one of four corners to reduce need for specific spares. Brake calipers are radial mount Wilwoods for additional
installed stiffness, and rotors are fully floating for improved pedal feel and longer life. Braking is, in a word,
fantastic. The wheels are made specifically for the Speads race cars, to our exact specifications, for light
weight, strength, and good looks.
The fiberglass body comes from a high quality mold, and is self-colored Gel-coat. As a result, it
requires no paint, so there are no ugly paint chips or "spider webs" to contend with. The bodywork attaches
with simple catch-latches requiring no tools to operate, and is manageable by one person. The
Floor and rear diffuser are vacuum
bagged, pre-preg composites for ultimate strength and minimum weight. The front and rear wings are made of
both aluminum extrusions and composites for light weight and economical replacement cost.
Engine & Drivetrain
The RM11 can accept almost any motorcycle engine. A Quaife differential is used at the rear. Unique to the Speads
is an angled engine installation, allowing for equal length halfshafts. This is not only another nod
towards reducing the number of spares you may want to carry, it also eliminates torsional moments
caused by unequal length halfshafts.
