Father and son team John and Richard Bridge both race Austin Healeys in the Midget and Sprite Challenge.
Our love for racing (winning!) has inspired us to seek out improvements in all areas of our cars. Each product has undergone extensive testing in real race cars before we offer them for sale - because we don't sell anything that we wouldn't use ourselves.
This is a special Cometic MLS gasket made exclusively for mamba motorsport for 73.5mm offset bored A series engines. It has 74mm bore through the gasket to allow the necessary 0.010" clearance around the bore to avoid any gasket overlap into the bore when fitted. Avoids detonation due to gasket hotspots Allows piston-in-head high compression engines Can be used for 74mm bore applications where the piston doesn't protrude the bore. Available from stock in 0.030" and 0.040" thickness - other options in 0.004" increments available by special order and cost will vary
Genuine APT VP8C Camshafts ground by Dave Anton in the USA to the highest tolerances - not to be confused with inferior copies. Developed by Crane/APT and Vizard, these very special camshafts produce exceptional power across the rev range making them "probably the best conventional race/rally cam available" - Vizard In our race engines we have been achieving 105+ bhp/litre (145bhp 1380cc) using this camshaft. They idle well and have excellent torque in the mid-range when compared to long duration race cams. Power Band 4000 - 7800 rpm. Usable to 8400rpm Please select Extra Carriage at checkout for this item.
Complete kit suitable for race cars and fast road/track vehicles. 4 pot alloy calipers (Wilwood) 245mm solid discs (9.6") Fittings Price INCLUDES VAT The Mamba big brake kit fits under most 13" alloy wheels and steel competition wheels like Weller. A replacement for the caliper and rotor gives a great road upgrade with m1144 pads or consider m1155 or bp20 for track days. For circuit racing we recommend the Hawk DTC30. Pads not included in kit.

The perfect solution for UK racers: 180mm steel clutch cover + bolts 180mm organic, sprung center plate Roller release bearing and billet carrier Lightweight steel flywheel (2.7kg) Saving over 4kg from the standard setup, this package provides a clutch that can cope with any A series race engine torque along with a smooth, progressive take-up that protects the transmission and low rotating mass to help protect the crankshaft. AND it fits in the bell housing without having to grind anything away. ARP crankshaft bolts are +£35.00 Please add £60.00 if you would like us to assemble and balance the assembly. Note if you have the crank out of the engine we recommend getting your full assembly balanced.
Mamba have teamed up with a main-stream distributor manufacturer to produce a special race-spec A and A+ race distributor. In answer to recent problems with quality from our usual suppliers we felt there was no option but to produce a new high quality product with all the features a club racer needs. Proper race spec rotor arm Electronic ignition Race advance curve designed for long duration ( >286 degree) cams. Finished with long silicone leads so they don't suffer vibration fatigue We believe this is now the best A series race distributor on the market. Available for A or A+ with either side or straight cap. Please specify your preference in the notes of your order.
Triple cylinder pedal box fits in standard midget / sprite mounting. Complete with balance bar, cylinders and cover. Clutch cylinder has integral reservoir and brake cylinders use a shared remote reservoir (due to the fitment angle in the car, an integral reservoir is less suitable but we can provide this as an option if required). Update: 2019 version has additional slot for mounting remote bias adjuster cable. Master cylinder sizes: 0.5 (1/2)" .625 (5/8)" .700" .75 (3/4)" Add the required master cylinder sizes in the comment box after confirming your order.
Mamba have designed a front suspension upgrade package that replaces the standard radial arm damper units. By using an MGB Shock Absorber the top king-pin mounting point is significantly strengthened, thus improving it's location and providing more consistent geometry. The 'Shock' is mounted on Mamba designed laser cut slider plates, which allow the camber angle to be set to better suit the application, i.e. circuit, sprint or hill climb. Includes plates, all bolts, nuts, trunnion bushes and instructions. MGB dampers are not included. Supplied unpainted so you can colour match to the chassis. may require the inner wings to be trimmed to clear anf brake lines moved slightly.
Laser-cut steel mounting plates and fitting kit. The plates sit between the damper unit and the chassis turret to allow fine suspension adjustment WITHOUT replacing the trunnion. Set your camber to any value 1.0 - 4.0 degrees. Allows you to dial out any minor inconsistencies. Note: the plates raise the inner pivot centre which gives improved toplink geometry for cars using shorter than standard springs. This results in less bumpsteer and less Camber gain in roll (ie more grip!) Kit includes: plates, nuts, bolts and instructions. Supplied unpainted so you can colour match to the chassis. may require inner wings to be trimmed and brake pipe moved slightly. We have full alignment setup in-house and can fit these and setup the camber and toe for you. Call for setup price.

These are proper, JWIS top quality automotive cam drive chains, made in Germany, NOT cheap industrial quality chain as most of the factors offer. It has taken me over a year to get access to this product - and believe me I don't fit cheap timing chains to expensive race engines if I can help it - no point in taking all that time & effort to get everything right to have it go off in 1/2 a season because the timing chain has stretched beyond use or worse still................! If you are running an inferior product on your £4000 engine, you really should think again! Available as Duplex or two types of Simplex (for those wanting the very minimum weight/drag on their cam drive)
