Motorsport Rear Wing Carbon Fibre MM183CF-S

High downforce rear wing for motorsports and race applications. Lightweight Carbon Fibre built with carbon ribs and spars. 2x2 3k Premium Carbon layup. Chord 225mm, thickness 18% @ 30%. High camber design. Max Width: 1700mm Weight: 2.1kg @ 1700mm w/o endplates DF (N) @ 100mph by Angle of attack: 0 - 694 2 - 874 4 - 975  6 - 1064  8 - 1123 10 - 1135  12 - 1011      Notes: This wing has high camber and thickness for a mid-size wing giving downforce levels at the top end of single plane performance (comparable with many 300mm chord wings) and overlapping with dual-plane wings whilst retaining single-plane levels of drag. Recommended AofA for maximum performance / drag / sensitivity is 7 - 8 Deg. When measuring the installed AoA with a straight-edge across the wing the AoA is + 0.5Deg from the measured angle (in free air). Standard construction is suitable for cars upto 140mph (max DF 2250N). We can produce a stronger but slightly heavier wing with additional ribs and 8/10mm mounts for cars capable of higher speeds, contact us to discuss your requirements.

Mamba MMVP8SP Camshafts replace the APT VP8C . Ground in the UK to the highest tolerances - not to be confused with inferior copies.

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 Instructions and setup information

Midget to MGB damper conversion kit

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.   Midget damper version also available  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.

Midget adjustable camber front suspension kit

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. MGB damper upgrade version also available. 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.

Cometic Race Head Gasket

This is a special Cometic MLS gasket made exclusively for mamba motorsport  for 73.5mm offset bored A series engines.

245mm (9.6") Midget / Sprite big brake kit - front

Complete kit suitable for race cars and fast road/track vehicles. This is an easy bolt-on upgrade that uses the original upright, hub and flexi line. No modifications are required to the original parts. 4 pot radial alloy calipers (Wilwood) 245mm solid discs (9.6") All Required Fittings and brackets Price INCLUDES tax. Fitting instructions    FAQ: Will the brakes fit in my wheels? -The Mamba big brake kit fits under most 13" alloy wheels and steel competition wheels like Weller. Standard Rostyle wheels could be used with a small spacer but we wouldn't recommend this much stopping power with them! Most Wire wheels will not fit but if you have a setup you think might work then give us a call and we can try to help. Do I need to modify my hydraulics system? -No. Our calipers work with the original master cylinder and give a good brake balance with the standard rear brakes. Upgrading to a 3- Cylinder pedal box does have advantages though if you are looking for ultimate track performance. What Pads should I use? -We recommend: - m1144 pads for fast road / lower power cars. -m1155 or bp20 for track days.  -Hawk DTC30 for race use or DTC50/60 on heavier cars.  Why aren't pads included? -Pads are not included in kit because there are so many options but are easily available from many stockists including Demon Tweeks, Merlin  Motorsport and Cambridge Motorsport. Pad Prices range from £37 (Wilwood) to £200 (Hawk DTC) for a set. Why aren't the discs vented? -Vented discs are much heavier (3kg per disc). Our first version of the kit used vented discs but we have run 245mm solid discs on all our recent race cars including with 10" slicks so there is no need for the added weight of vented discs when running the correct pad spec.  Can the discs be cross drilled and/or slotted / dimpled? -Yes. They are iron rotors suitable for machining before use. Why are they not slotted? -Midgets just aren't that heavy or fast (even the fastest race cars) so they don't tend to create enough pad gas to make it worthwhile. Getting them machined typically costs £100 per pair if you really need it and can be done by most competent machine shops. Can I purchase spares? -Yes. All parts are available as spares just give us a call.
