Performance Is Looming 

Performance Is Looming was set up by James Wills in 2013. After struggling to find a Cosworth engine loom supplier who could meet our high standards, It was the case that we could do far better ourselves, and so Performance Is Looming was born in 2013 and has grown ever since.


We have quickly become well known for producing high quality wiring looms that will out perform any other by using different methods to ensure the performance is maintained even under extreme conditions.


Specialising in Performance Fords and in particular the Cosworth models, We aim to make wiring looms that do not suffer from the problems many others have.

As we are in the tuning industry ourselves, we are able to constantly test and evaluate our products, We have spent hundreds of hours testing and ensuring that the final wiring looms we produce are the best performing on the market today.


The wiring Loom is the vein of the car and second best is not an option.

All of our looms are personally hand made. 


We make these looms on a custom basis, so if you want a loom made to your own measurements, just ask us for a measurement sheet.


Each engine loom has a unique serial number which allows us to offer support and future upgrades to suit your dedicated loom.


Every loom comes with full fitting instructions.


We offer several types of loom finish, from the most common motorsport polyester braiding, to glass fibre heat resistant braiding or PVC tape to replicate the OE looms ideal for concourse cars, we can also use Flexible Rubber Shrink to protect the looms and make them water and dust tight. 


We offer a full fitting service on a "Drive in Drive out" basis at unbeatable prices, so if you dont feel confident to fit the loom yourselves feel free to give us a call and let the experts take care of it for you.


Trade enquirys are welcome please email us for details, we are happy to discuss your needs and drop ship if required.
