Although
not really a racing car the DRK deserves a place on this web site.
The original idea for the car was formed between a good friend and myself
and by the mid 1980's the DRK had forged its place in the kit car field,
to the extent that by the end of our production run there had been 59
cars built, all of which are in good regular use.
The Story of D.R.K. Kits, by Keith Hamer
Unlimited enthusiasm, Limited production.
Way back in 1985 a good friend, Derek Callister, and I decided that after
many years rebuilding, fixing, and generally messing about with cars of
all descriptions, that we would build a car to our own design. This design
was initially inspired by early post World War II racing cars, particularly
the Tolbot Lago. We set about formulating a design brief to work from.
This brief was subsequently changed several times before the car finally
appeared, but to start with it was:-
- Front wheel drive
- Four cylinder water cooled engine
- Separate steel chassis
- Aluminium body
- Two seater sports tourer
Having decided on the original concept the search was on for a suitable
donor vehicle. Fortunately the search was not to take very long at all.
At the time, Derek's father and his two partners ran one of the biggest
car body repair shops in Ellesmere Port and it just happened that a Renault
6 was in for repair at that time. It turns out to be one of the only front
wheel drive cars running an inline water cooled engine, so the die was
cast. The next job was to find a suitable car to donate its innards to
our project and to strip it down. We did it in one weekend. I remember,
having taken the body off this elderly R6, we proceeded to thrash it round
the workshop yard, - to test its potential of course! The suspension geometry
was then duplicated on the workshop floor and we set about cutting lengths
of 40mm by 80mm, 3.2mm box section steel to form the chassis. At this
point we came across our first problem.
The
R6 has torsion bar suspension, parallel with the chassis rails at the
front and across at the rear. (Have you ever looked at Renault cars closely?
The wheelbase of the offside is different to that on the nearside. This
is due to the fact that the torsion bars run across the rear, one in front
of the other.) A serious rethink was required if we were going to retain
the torsion bar suspension. The answer came to us like a blinding flash.
We would have 3 wheels on the car, that way we only needed to find room
for 3 torsion bars. (Pretty good thinking we thought - not only does it
mean that we only need room for one bar at the rear, but it was also cheaper
to tax a 3 wheeler.) The truth is the design went a bit further than that
because the torsion bar in the rear was substituted by a proprietary coil
spring and damper unit, with the Renault 6 rear hub grafted on to our
own radius arm. This finished off the rear.
The Renault 6 front suspension was fitted complete, along with the R6
1100cc engine, 4 speed gearbox c/w dash change and R6 steering box. This
finished off the chassis. As the body was now for a three-wheeler, it
almost designed itself. Taking styling cues from other three-wheelers
the design we ended up with, I think, is quite sweet. It's a cross between
a Morgan 'F' type and a B.S.A. constructed traditionally with a wood frame
and aluminium panel work. The only concession to the 1980s being glass
fibre cycle wings. From a very early stage Derek's dad, Bob, was enlisted
into the project, not only as adviser and welder, but as body specialist
and financier too. The first (and we thought only) car was finished in
dark blue cellulose paint. When the project was unveiled at the Cheshire
Kit Car show in May of 1986 it caused quite a stir. Everyone who saw the
car fell in love with it in the same way as Derek and I fell in love with
the original idea. From that point on D.R.K. (Derek, Robert, and Keith.)
Kits did not look back. During the rest of that year, Bob Callister was
badgered by numerous people to build them a D.R.K. and eventually it was
decided that the first production D.R.K. would be made.
To
this end we made some minor modifications to the original, taking the
form of 1" extra in the width, height and length, together with a
slight reprofile of the body line. D.R.K. continued in this way with D.R.K's
being built in spare time alongside more mundane tin body repairs until
1990 when, having sold the business of Callister & Roscoe body repairers,
Bob and his brother and long term partner, Brian Callister went into full
production building D.R.Ks to order. As the production run went on, the
cars were steadily developed. The most recent car to be delivered representing
the present development. All cars were built to order and, although the
basic specification remained unchanged, in all cases the specifics of
the individual car were always for the customer to decide upon. It allowed
total freedom of expression and a very individual car to be produced.
All cars were finished to a very high standard and to an advanced state
of build. Effectively all the customer was required to do was fit the
engine and gearbox, to connect the water pipes, and fit brake pipes, etc.
All cars left D.R.K. with a fully built and painted chassis, on which
the donor car suspension was fitted, checked for wear and replaced if
necessary, our rear arm and hub complete with damper/spring assembly,
and all the suspension geometry was set. The body was fitted to the chassis
and finished in cellulose paint in the customer's choice of colour. All
trim was fitted again to the customers specification, complete with tonnaeu
cover, and hood if required. The dash was covered in either wood veneer
or leather cloth with all instruments supplied, fitted and wired in. All
lights were supplied, fitted and wired in, a spare wheel carrier, windscreen,
luggage rack, fuel tank, and brake line kit completed the package. D.R.K.
Specification:-
- Chassis - 40mm*80mm*3.2mm steel box section ladder frame chassis finished
in chip resistant paint.
- Body - Wood frame clad in 20swg aluminium. 18swg aluminium grille
surround, bonnet, and rear deck, finished in cellulose paint.
- Trim - All trim fitted, consisting of padded seat base and back, padded
cockpit roll, side panels, tonnaeu cover, and hood.
- Ancillaries - New wiring loom made up and fitted to the car, all lights
fitted, (front headlights dip/full beam with side light, wing mounted
indicators, rear stop/tail and indicators) instruments to customer specification
fitted, steering wheel, hand brake c/w cable, radiator, brake pipes,
and exhaust all supplied.
D.R.K. ceased production in June 1998, due to Bob and Brian taking well
earned retirement, having produced 59 cars.
