Performance & Upgrades

Full Restorations, Service, Parts and Expertise in all Classic British Marques.

Originally, these vehicles were built to be affordable. Thy utilized the technology available at that time. For the period, this generally afforded a well functioning and economical engine, brakes, and suspension. Although the 'Bean Counters' had a lot to say about the way a vehicle was built,  they really are decent when compared to other vehicles of the age. The problem? We've moved on. This is the Future. WELCOME! Speak to us about keeping up the appearance and the 'Flavour' of your Classic British Vehicle, while simultaneously .

Going Beyond.

Break out of the mundane with today's automotive standards. BMC can help you enjoy the character of your Classic with improvements in braking, handling, acceleration, gearing, cooling, cabin comfort, as well as many other improvements.

From modest updates and upgrades to full race engines we have done more with British iron then most other shops could ever imagine. We understand the parts, have the sources and resources including our vast library of information and technical knowledge to increase the power for your desires.


The main reason people increase power is the car becomes much easier to drive in traffic; going from nervous under powered to confidently enjoyable. Others enjoy surprising people with what a classic British car can do; these cars are so light that substantial increases come from even minor power improvements. For some its just their needs, their requirements - their ambitions: a craving to which can not be explained in words but all of us who own these cars understand this craving. Your completed vehicle leaves our shop with us knowing you’ll have full confidence merging into traffic and have a feeling of oomph come from wide open throttle.

Engine Upgrade, or Conversion?

We've introduced many  Original Drivelines to increased Performance. Larger bore, Better Camshaft, Stronger Ignition, Improved Flowing Cylinder head, Lighter Rotating Assembly- Street OR Race Engine.


Sometimes the maximum powered reliable (street-able) standard engine is not enough. When you want to go from “keep up” to “fly past” an Engine Conversion May be the best option. Along with building Strong Classic British Engines, we are well known for our Engine Conversion products and installations. If this is a direction you would like to take, please have a conversation with us to see how we may match the engine/Driveline of your choice, with a budget that matches what it realistically requires, Reliably.

High Speed Differential Upgrade

In the midwest (Plains/Flatlands) you might not need the short gears that were designed for lower speeds between the Hedgerows in England. Since these vehicles were produced, many roads have been paved, flattened, and are generally taken at higher speeds. Fitting a higher speed (lower Numerical) differential gear set will give a higher vehicle speed while achieving lower and more comfortable engine speeds for a much improved Driving Experience.


5 Speed Conversion

Cruise at a lower RPM with a new top gear. Sometimes the five speed conversion is done by itself, and sometimes this is completed in conjunction with a high speed rear axle gear set. We'e found many who like the five-speed upgrade just to get the earlier cars to shift into first without grinding the original non-synchronized first gear.

General Tune-ups

Get more power from the classic British engine you love can often take place with a simple tune up. As mentioned in Engine upgrades, we can do quite a bit while rebuilding your engine, but sometimes it just requires a little tuning. We've tuned engines that clients thought had no life remaining, only to find decent performance and years of enjoyment left on their clock.


Suspension Upgrades

Enjoy the drive with a smoother ride and better cornering. We use improved suspension bushings, larger anti-roll (anti-sway) bars, and aftermarket suspension systems where required.


All this said, we understand those who wish to keep their vehicles look and feel authentic as newer technology does not always magically transform a car into something else. The Truth is- when going from worn out original to rebuilt decent original OR aftermarket, the ride most often improves substantially. For those who are convinced they must move away from the original suspension, we suggest that is Commonly Untrue! Most often, street cars are rebuilt using original type suspension components with a few enhancements. This generally produces great results for many Decades to come.
