Rush SR vs FC Spec
Rush SR vs FC Spec
One car is out of production and losing series support. The other has an active manufacturer, a growing national series, and parts you can actually buy.
What Is FC Spec?
FC Spec — originally called Formula Continental — is a single-seater class based on the Van Diemen RF00 chassis with a 130hp Ford Focus 2.0L engine. It raced under SCCA in the Formula Car Challenge series and gained a following in the mid-2000s through mid-2010s. The Van Diemen factory stopped producing the RF00 around 2012, which means every FC Spec car in existence today is at least 13 years old.
That’s not automatically a dealbreaker — plenty of spec classes run older chassis successfully. But it shapes almost every aspect of ownership: parts availability, series participation, resale value, and the long-term viability of the class.
Side-by-Side Comparison
| FC Spec | Rush SR | |
|---|---|---|
| Car availability | Used market only (~$15,000–28,000) | New from $49,995 |
| Manufacturer support | None (out of production) | Active — Rush Auto Works |
| Parts availability | Used market, occasional NOS stock | In-stock, current production |
| Annual running costs | $18,000–35,000 | $10,000–14,000 |
| Typical crash repair | $5,000–20,000 (composite tub) | $3,000–5,000 |
| US national series | Diminishing — primarily club racing | Active 6-round national series |
| Typical grid size | 5–15 cars regionally | 25–50 nationally |
| 5-year outlook | Uncertain — parts getting scarce | Growing series, active support |
The Parts Problem
This is the core issue with any car that’s out of production: you’re racing against a shrinking parts supply. Every season, more FC Spec cars get crashed, parted out, or retired. The pool of available spares shrinks. Prices go up. Lead times get longer.
Composite Tub Risk
The Van Diemen RF00 uses a composite monocoque tub. A significant impact can crack or delaminate the tub, which in a current-production car is a straightforward warranty/parts order. In FC Spec, it means finding another used tub, having it inspected, and hoping it isn’t hiding damage from its previous life.
Engine Rebuild Supply
FC Spec uses a spec Ford Focus 2.0L with tightly controlled rebuild specs. The parts are Ford-sourced, which helps. But experienced FC Spec engine builders who know the specific quirks of the class are fewer every year as the series shrinks.
Series Participation
Without manufacturer support and a growing calendar, FC Spec events depend entirely on club organizers maintaining interest. Grid sizes have trended down since the class peak. Smaller grids mean less competition, less exposure, and reduced motivation to keep the car competitive.
Why Some Drivers Still Choose FC Spec
Entry Cost
A well-prepared used FC Spec can be had for $15,000–22,000. If your primary constraint is initial outlay and you’re willing to accept the parts/series risk, it’s a lower barrier to entry than a new Rush SR.
Regional Community
In certain SCCA regions, FC Spec still has a dedicated community of drivers who know each other and run competitive club events. If your priority is local racing with a familiar group, the existing FC Spec community in your region may be exactly what you’re looking for.
SCCA Points Ladder
FC Spec counts toward SCCA national championship points, which matters if your goal is SCCA’s competitive structure. The Rush SR runs primarily under GridLife’s championship, which is a different ecosystem entirely.
Frequently Asked
Can I convert an FC Spec to run in Rush SR events?
No. Rush SR events require the Rush SR spec car. They’re completely different vehicles with different specs, safety requirements, and homologation. FC Spec and Rush SR don’t share any competitive structure.
Are there drivers who moved from FC Spec to Rush SR?
Yes, and consistently they report that the Rush SR is a more rewarding car to drive — more power, modern gearbox, better tires — in a more competitive field. The transition from FC Spec driving technique is straightforward since both are open-wheel spec cars.
Which is faster?
Rush SR. The 1000cc motorcycle engine makes 150hp at 11,800rpm. At 1,130 lbs, that’s 0-60 in 3.3 seconds. FC Spec makes 130hp and weighs roughly 1,100 lbs, but the Rush SR’s paddle-shift gearbox and more aggressive power curve give it the edge.
What happens when I can’t find parts for my FC Spec?
Your options are: buy another FC Spec for parts, have custom pieces fabricated (expensive and may void spec homologation), or retire the car. This is the fundamental long-term risk of owning an out-of-production race car. It’s not hypothetical — FC Spec drivers are navigating this right now.
Built for the Long Run
