Bonnet Frame

10th March 2019

With the scuttle 80% done, this Locost was starting to look less and less Hot Rod and more 70’s saloon. I want this car to look like a modified late…

Windscreen Surround

10th February 2019

Motivation to complete my windscreen surround has been lacking. Poor health means I'll never drive this Locost. You can take the man away from his Hot Rod, but you can’t…

Bespoke Steel Scuttle

Hand built Bodywork – Drivers Side Door Pillar

This is not a DIY Sierra brake upgrade, more of a complete re-think. A set of W220 Mercedes callipers came up for less than £25 (inc. delivery).

Setting up Inboard suspension on a kit car is a time consuming process. one that involves hours of measuring, clamping and tack welding.

Haynes Roadster Mushroom Adaptors

Ford Sierra Mushroom adaptors are available from many Haynes Roadster and Kit Car sources, but I needed some special ones to fit my 4x4 uprights.

Push Rod Suspension

Push Rod suspension doesn't have to be complicated, many kit cars or Haynes Roadsters could have it at virtually no extra cost.

Push Rod Cantilever Suspension

The push rod suspension on the rear of this Haynes Roadster is almost complete. The reduction in un-sprung weight should help handling, but more importantly they look GREAT.

Front Suspension A Arms

Haynes Roadster Lower Front A Arm

Rover V8 MegaSquirt P38 4.6 – extraEfi – 2

Kit Car 4×4

Building a 4x4 Kit Car isn't easy. Building a 4wd sports car from scratch is even harder. Getting the Sierra front differential to fit has been slow but surprisingly simple.
