Caterham CSR – F1 Green – SB100 Registered

[NecronomiconJules]

I thought I'd give the knowledgeable and discerning folks on this site first dibs. 

 

With real reluctance, I’m putting my Caterham CSR up for sale. I’m relocating to Europe shortly, and importing/registering a US Seven there would be a long, expensive, and bureaucratic adventure I’d rather avoid. 

I am the original owner. The car was built for me, and very solidly built, by Rocky Mountain Caterham from a brand‑new CSR chassis in 2020. The engine and gearbox were sourced separately, per US EPA Kit Car Policy. The goal was simple: create the most agile, communicative and confidence‑inspiring road car possible. No racing, no track days — just pure back‑road performance.

 

Specification

Kit

• CSR chassis kit in Caterham F1 Green (the pictures don’t do it justice)

Engine

• Used 2.0 Duratec, reportedly 210 bhp (true output unknown, but the performance supports the figure)

Gearbox

• Type 9 with Tracspeed semi‑helical gearset (long 1st, close 2–5)

Registration

• California SB100 (SPCNS) — smog‑exempt, no annual emissions testing, and you skip the usual SPCNS registration gauntlet

What This Car Delivers

You end up with a 1290‑lb, ~200‑bhp Caterham built on a Multimatic‑engineered platform — inboard front suspension, the only IRS in Caterham history, and a level of composure that, in my opinion, sets it apart from other Seven expressions.

The handling is the CSR’s party trick: poised, unflappable, and absurdly fast across real roads. It shrugs off mid‑corner bumps, stays balanced no matter what you throw at it, and covers challenging terrain at WRC-like pace with unerring ease.

Steering is razor‑sharp, richly detailed, and free of slop. The Duratec pulls from 2500 rpm and then charges hard to a 7800 rpm redline with a hint of BDA‑like sonority up top. The upgraded brakes match the chassis: powerful, progressive, confidence‑building.

It is, without question, the most nimble, responsive, and sure‑footed road car I’ve owned. And everyone loves it, from 5-year olds to Porsche drivers, even Harley riders give it a thumbs up.

 

The Imperfections (in the spirit of full transparency)

• Slow oil seep at the main seal — improved but never fully eliminated. “They all do that, Sir.”

• Slight kangarooing at steady-state light throttle around town; disappears above ~30 mph

• A few small paint chips; it’s a driven car, not a museum piece

Included Extras

• Full hood and weather gear

• A new set of Avon CR500s (195/45‑15 & 245/40‑15) — likely among the last available

• All original parts, except the steering rack and open differential

• Various fluids (engine, gearbox, diff, brake, coolant)
