Kit Car Bonnet Height

The height of the bonnet was too high.

So high, it would be hard to see over.

Lowering the height of the bonnet was just an excuse to make the obligatory ‘Brum Brum’ noises.

A replica Lotus 7 nosecone, sat on top of the chassis (McSorley 442 front end dimensions), simply sat up in the air and looked wrong.

I looked into cutting the nosecone up:

  • Slicing it through the middle and making it taller.
  • Cutting a V in the side profile
  • Making a new noise from many pieces

In my head, none of these really worked. When a design has such classic proportions, messing with them just doesn’t seem right.

One problem with keeping the standard profile is that it doesn’t fit over the front of the McSorley 442 chassis. On the original car, parts of the chassis tucked inside the nose. With the McSorley proportions I could not make this work to my satisfaction.

The nose cone simply doesn’t fit and is way too high.

There were other problems. With the cockpit area of this chassis being 4 inches wider than the original, looking down from above the side profile had a big kink in it.

I like my lines to flow or at least be straight. – This doesn’t satisfy either of those criteria. At one point there is over an inch gap.

Kit Car Chassis - Cutting It Up

Crank up the disc cutter, the chassis is too big!

I’ve dropped the height of the top rail from 381mm to 325mm. I have dimensions that are allegedly of a standard Lotus 7 S2.

The height of the top rail is 13inches (330.2mm).

With the top chassis rail at 325mm everything seems to work much better. Note the original chassis had a small kick-up at the front and this chassis doesn’t – hence the difference I made in the height of the top rail.

The rear of the nose cone has had small cuts made into it to improve the profile from the top. My worries have been solved.

This chassis is now:

  • 100mm longer (~4 inches)
  • 100mm wider (~4 inches)
  • 5mm less tall (-0.2 inch)
