All PERON performance hardware goes through a rigorous research and development programme. From initial idea and early sketches, through to prototyping and testing, we invest a great deal of time and energy to ensure each new product satisfies our stringent technical requirements.

Identify an area to improve

The first stage is to identify an area that we feel could be improved upon. This may be something relatively straightforward such as a restrictive stock downpipe, or more involved as with our latest STG4 turbocharger package for the Fiesta ST Mk7. In all cases we carefully examine, measure and test the stock part to find its limitations. Often this is prompted by our other development work. For example, when calibrating an ECU, it may become apparent that the cooling system is insufficient, or a restrictive exhaust system may be holding back power gains. The first question we ask is: can we improve on it? Followed by: How do we achieve it?

Nortech Performance

From here we work closely with our in-house technical partners, Nortech Performance to create a solution. Utilising industry-leading SolidWorks CAD software, our automotive engineers draw the new product according to the specified measurements. Cutting edge simulation software is then used to model the product’s performance.

With full fabrication, CNC machining and a team of four TIG-welders based in-house, we are ideally equipped to produce prototype parts. We don’t have to wait for parts to arrive from third parties, so we can make changes quickly and efficiently.


Once our team of engineers are happy with a prototype part, it is then subjected to intensive testing. This often involves time on the dyno with the part installed, or by using other equipment such as a flow bench for intake systems. In each case we work hard to identify performance gains and also to pinpoint areas where we can improve.

The final stage is to test the new part fitted to a development car in real world scenarios. We do between 3,000 and 6,000 miles to get an in-depth picture of each new product. Only when we are completely satisfied will a product make it into full production.

It is essential that all PERON products must offer a tangible performance benefit. However, of equal importance is that it does not adversely affect the vehicle. By this we mean that it retains its character and offers OEM-levels of drivability. Simply put, PERON performance parts must enhance the driving experience.

Development Cars

We use a dedicated fleet of vehicles for development work, which means we have full access to test data. Whether testing new ECU software to ensure impeccable throttle response, or a carrying out a complete turbo installation, we drive all of our test cars in a range of conditions to iron out any issues. Our current fleet includes the following vehicles: Focus RS Mk1, Focus RS Mk3, Focus ST Mk3, Fiesta ST Mk7, Golf Mk7 R, BMW M4, Mercedes AMG C63, Audi RS7 and Nissan GT-R.
