BG Developments




Brian Moore - Astra B

Brian Moore is a perfect example of our Rally offering. Having dusted off his Astra B rally car from his youth - Brian set about re-creating a “Works” rally car, which would be competitive against much more modern machinery.

To keep his existing period wheels, we tried numerous caliper iterations before settling on the sculptured CP6760 caliper - which still needed CNC machining to fit perfectly into the wheel. Married with AP Racing discs, bespoke mounting bells with integral spacers, it all looked great on the Pilbeam strut.

Competing with his son Ben on the Brean Stages Rally (a round of the ASWMC championship) at 75th and finishing 27th overall - picking up the PIAA Lighting best under 25 award.

54TEL 0637aBrian is not finished yet, and has a significant engine upgrade planned for later in the year.


Rallycross SLK

Richard Moore is creating a somewhat unusual Mercedes SLK rallycross car fitted with a BMW V8 engine. Brakes are particularly important on the tarmac sections, and Richard opted for CP5040-2/3 calipers at the front and CP5040-10/11 calipers to the rear. Again using AP Racing discs and BG Developments bespoke mounting bells and carriers – the results were just what he needed.




Rallycross SLK

For maximum performance we have lightened and floated the front and rear disc assemblies for the Mercedes SLK rallycross car. Made in high strength aerospace grade 2014 J6 and hard anodised for durability, the SLK set up should be ideal for the new season  richard-moore brake1

BG Developments can provide discs, caliper refurbishment, clutch parts, pads and AP Racing high temp racing fluid for F1 and F2 Brusca cars

Sean Blakemore

Wayne Blakemore is not someone who is not the sort of person you say “no” to. He is a physical presence, imposing, forthright and determined. His son Shaun comes across as being the complete opposite – but this is deceptive. Behind his quiet exterior, Shaun is equally determined, and has risen to the peak of Stockcar racing very quickly. Despite being the youngest in F1 when he was 17, he has wisdom beyond his years - constantly developing his car, trying new parts, and understanding what works and what doesn’t. Shaun’s passion for building, modifying and racing in Brisca F1 is ideal for us where our parts are developed and tested to the limit.

Previously BG Developments had the pleasure of working on the original GT40 which finished 3rd at Le Mans 1966, (when they famously finished in 1st, 2nd, 3rd formation). The car was put  back to its correct braking set up so that It could compete at the Le Mans Classic. Its previous owner had fitted modern 4 pot calipers, which eliminated it from FIA events.

At the factory, we manufactured the Calipers, Discs and Mounting Bells to the original specifications - and the car has since tested and competed in several races with great success.

BG Developments has a long history is providing brake solutions to circuit racing cars. 

We hold suspension details for many of the more popular race and track day cars, but often are provided with a wheel, upright and lower ball joint and build a bespoke braking solution around them.

We frequently attend the first test and race days for new customers to ensure that they are 100% happy with the parts provided, and help with any potential issues around pad selection, bedding etc.

We are familiar with float in disc, float in bell and solid bolted disc bell assemblies, and can fit bias springs if required.

It's easy to get started creating your website. Knowing some of the basics will help.

What is a Content Management System?

A content management system is software that allows you to create and manage webpages easily by separating the creation of your content from the mechanics required to present it on the web.

In this site, the content is stored in a database. The look and feel are created by a template. Joomla! brings together the template and your content to create web pages.

Logging in

To login to your site use the user name and password that were created as part of the installation process. Once logged-in you will be able to create and edit articles and modify some settings.

Creating an article

Once you are logged-in, a new menu will be visible. To create a new article, click on the "Submit Article" link on that menu.

The new article interface gives you a lot of options, but all you need to do is add a title and put something in the content area. To make it easy to find, set the state to published.

You can edit an existing article by clicking on the edit icon (this only displays to users who have the right to edit).

Template, site settings, and modules

The look and feel of your site is controlled by a template. You can change the site name, background colour, highlights colour and more by editing the template settings. Click the "Template Settings" in the user menu.

The boxes around the main content of the site are called modules. You can modify modules on the current page by moving your cursor to the module and clicking the edit link. Always be sure to save and close any module you edit.

You can change some site settings such as the site name and description by clicking on the "Site Settings" link.

More advanced options for templates, site settings, modules, and more are available in the site administrator.

Site and Administrator

Your site actually has two separate sites. The site (also called the front end) is what visitors to your site will see. The administrator (also called the back end) is only used by people managing your site. You can access the administrator by clicking the "Site Administrator" link on the "User Menu" menu (visible once you login) or by adding /administrator to the end of your domain name. The same user name and password are used for both sites.

There is much more to learn about how to use Joomla! to create the website you envision. You can learn much more at the Joomla! documentation site and on the Joomla! forums.
