We won't try to convince you why Bill Rawles Classic Cars is the best place to upgrade your classic car. Our race cars speak for themselves with reliability and performance developed on the race tracks of Europe while the technology, experience, and knowledge required to make Austin-Healeys relaibly fast filters down into our road cars.

Do you really need modern alternatives? If you consider, during the Spa 6 Hours our race cars are on the limit for the full six hours of racing, hitting the 7,000 rpm red line every lap, making 2,280 gear changes and stopping twice for fuel in over 500 miles of racing. Every lap the car is braking from 130 mph to 58 mph at the end of the Kemmel Straight and yet our race cars are built to FIA standard and fitted with brake components only available in period.

As well as numerous club racing wins, Bill Rawles Classic Cars' machinery has also had notable success at national and international events such as: Spa 3 hours Class winners, 4th Overall. Spa 6 hours Class winners, 16th Overall. Castle Combe Autumn Classic, Winners. Zandvoort, Runners Up. Lap records at Zandvoort and Portimao.

Improve performance

Engine, transmission and final drive upgrades

Our popular fast road conversion takes technology developed in our race cars on the track and tames and refines it for road use. This will vastly improve the performance of your classic without destroying its soul or making the car difficult to live with. Not to be mistaken for our competition or race upgrades.

Engine:- Full rebuild to fast road spec with optional steel crank and rods. Parts include but are not limited to - fast road cam, fast road head, aluminum sump, omega pistons and bucket followers.
Gearbox:- Rebuilt with straight cut tulip or Sebring ratios, uprated competition overdrive.
Final drive:- exchange unit 3.54 ratio limited slip differential.

Recommended as a full package but we can fit individual upgraded parts. Engine BHP lifted with an option to increase steering response with a high ratio steering box. Full running gear package from £22,000 and individual items available and priced separately, please contact us for details.
There are many options and we can discuss your requirements to build the best package to suit you, please contact us with to discuss details, with no obligation. These uprated units can be supplied fitted and tuned to your vehicle or in crate form.

100 to 100 'M' spec upgrade

Upgrade your standard 100 to M Spec and bring your four-cylinder Healey alive. Around 640 'factory' cars were built and a further 500 'dealer fit' cars were converted. The upgrade to M spec is very involved and isn't just a case of a louvred bonnet and strap! M Spec pistons, camshaft, fitted and colour-matched louvred bonnet, strap, 1"3/4 SUs with M spec inlet manifold and cold air box. BN1s have uprated roll bars and stiffer suspension. We will also fit an M spec aluminum cylinder head. In most cases, this conversion results in a full engine rebuild. The full M Spec conversion from Bill Rawles Classic Cars, prices from £13,500.

Improve Reliability

If you're an enthusiast looking for some basic upgrades to improve your Healey or any classic, we would recommend starting with a negative earth conversion, 12v plug socket for a sat nav or charging (optional), fitment of a high torque starter motor, alternator conversion, spin-on oil filter kit, solid state fuel pump, five-blade plastic fan and our radiator with uprated core. This will give you more reliability - especially whist driving at night - the car will turn over and start easier, and engine oil filtration will be improved. The five-blade fan and uprated radiator will almost guarantee trouble-free driving during the hot summer months. We would not recommend a kenlow fan as a replacement. Reliability can be vastly improved from £500 to £2,500. - Contact us for full details.

Improve Visibility

Improve your night driving and safety with our LED side light kit or Halogen head light upgrade. We will also replace your side lights to our unique package which enables earlier cars with single side lights to have LED front and rear combined yellow and red side, brake and indicator lights, also available for all classic cars.

Improve Interior

Improve the cabin of your classic with the addition of seat belts, Moto-Lita steering wheel, 12v power plug and LED backlit gauges. If you would like to add a personal touch, tidy ups or full interior retrim are also available as well as custom trim work - almost anything is possible.

Two-Tone Paint

Should you have a 'solid' colour Healey and would like to add a two-tone side, please get in touch to discuss the options. Or vise versa, two-tone can be easily painted single tone.

Wheel & Tyre packages

Wheels and tyres can completely change the look of the car. We can offer a range of tyres and sizes as well as wheels for all classic cars in painted or chrome. We also stock Vredestein tyres for same day fitting. For fast road or track days, we recommend Avon ZZ tyres.

Windscreen & Mirrors

If you're wanting upgrades to visibility, we can offer replacement windscreens in standard or with a heated element. Improve safety with door mirrors, which are available in a range of styles.

'Works' Rally Upgrades

'Works' wing vents, spotlight pods, side exit exhaust, spotlights, hard top, Minilight style wheels and spare wheel boot lid. Matched perfectly with our fast road or competition spec.
