Product Description

All parts whether purchased through Forge UK, Forge US, Forge Asia or one of our dealers, its life started at our headquarters in the UK. Forge has a long association with making performance parts for previous Mini’s and these are the latest for the Gen 3 Mini.

The Underbody Brace kit was designed by our highly skilled Research and Development Team at Forge Motorsport UK HQ.  Using the best software on the market we simulated structural tests on multiple designs to see which came out on top. Once the design was decided sample braces were machined and bolted onto the vehicle for testing. After weeks of extensive R&D we concluded that our design was far more superior than the OEM. Adding ridigity and support to the chassis and suspension.

Both braces are CNC machined at Forge UK HQ based in Gloucestershire, England from a single block of billet aluminum, it is the highest quality of 6000 series aluminum alloy.  Following a quality control check they are anodised in the "Forge Blue" color to give it an aestheticly pleasing and elite look.  We offer our Forge Motorsport Limited Lifetime Warranty on the material and manufacturing process of the braces.  Due to the harsh environment of where they are fitted we cannot offer warranty on the anodised finish. 

We managed to create a part that is incredibly simply to install and can even be fitted with the existing (OEM) bolts from the vehicle. 

** The upload date is shown as the part is still a production part on current vehicles.

Do not use aggressive (acidic) car cleaning products, particularly traffic film remover solutions or shampoos to clean your intercooler, radiator or oil cooler. The use of these products can damage Forge Motorsport cooling systems and invalidate your warranty. These are often found at car washes. A light, warm, soapy solution (free of harsh acidic cleaning compounds) should be used to clean you cooler and thoroughly rinsed away. We recommend that you should inspect your product on a regular basis for bent and/or crushed fins. Any bent fins should be carefully straightened to allow ambient air to pass through the core face. At the time of installing your Forge radiator, an approved coolant must be used and added to the coolant system. Be sure you never mix coolant and always use distilled water.
