1958 MG A Roadster

This owner kept meticulous handwritten records and accumulated a substantial collection of parts receipts, primarily from Brown & Gammons; their tenure appears to overlap with or precede the 2006 overhaul period based on documentary context.

Period competition appearances at Silverstone documented in the car's history, confirming long-standing circuit use.

Period competition appearances at Snetterton documented alongside Silverstone entries, reinforcing the car's historic racing association.

Full engine strip and inspection during winter 2006; components renewed included big-end bearings, timing chain, distributor drive, cam followers, valve springs, high-performance oil pump, Piper 300 rally cam, and roller rocker gear. Cylinder head skimmed to 11.1:1 compression with inlet and exhaust ports reshaped and gas-flowed.

Also included fitting a lightened flywheel, refreshed clutch, upgraded cooling system with electric fan and high-capacity radiator, Lumenition ignition, and a replacement MGB starter motor.

Roof removed as part of conversion from coupé body to open competition configuration; car also converted from left-hand to right-hand drive at some point prior to 1974.

Both the RHD conversion and roof removal were completed before 1974 according to the catalogue.

Original three-synchromesh gearbox replaced with a later four-synchromesh MGB overdrive unit; transmission tunnel modified to accommodate the new gearbox.

Described as carried out during earlier, undated works prior to the 2006 engine overhaul.

Initial high-performance engine build, details unspecified, carried out approximately twelve years before the 2006 strip-down, i.e. around 1994.

The 2006 overhaul notes this was the engine's first strip-down since the earlier build roughly twelve years prior.

Subsequent engine rebuild by Slark Racing increasing displacement to approximately 1,800cc; internal work included balanced connecting rods and crankshaft, uprated pistons, tubular exhaust manifold with large-bore tuned system, and high-output oil pump with supplementary oil cooling. Quoted power output approximately 150bhp.

Additional work referenced in the history file involving Simon Hadfield, Maxspeeding, and Hungerford preceded or accompanied this rebuild.

Chassis and braking upgrades comprising front disc brakes with MGB calipers and servo assistance, uprated suspension with telescopic dampers, anti-roll bar, revised geometry, Quaife limited-slip differential with 4.3:1 ratio, Panhard rod, and anti-tramp bars.

Alloy wheels, bucket seat, TRS harness, roll-over protection, and a competition fuel cell were also fitted as part of the weight-reduction and safety-focused build.
