ATTENTION
Before you can continue, you must agree to all of the following terms:
The RM Series is comprised of a damper cartridge secured within a threaded outer body. This specific design requires a lubricating grease to be applied during the assembly process between the two damper and threaded body to avoid metal-to-metal contact. In order to keep the two components from touching each other and generating noise transmission you will need to periodically clean out the old grease and apply new grease.
This is a simple process that can be done with just a few common tools. It does not require you to open the internals of the dampers themselves and therefore you do not need to have the dampers re-pressurized after carrying out this procedure. Please contact us on info@mlperformance.co.uk for more information and a step-by-step guide on how to complete this maintenance.
As a result of this required maintenance, we do not recommend the RM Series for road use over the BR Series or ER Series.

The Brembo GT Big Brake Kit utilizes some the most high-tech materials available on the market today. Using their 50+ years of knowledge, Brembo's products have been engineered to perform both on and off the track.
The brake calipers for the GT | BM systems are made using an innovative 4D technology casting process used here for the first time ever in the manufacturing of car calipers. This casting process makes use of a technology that has allowed Brembo to offer a design that is completely different compared to what is generally offered for this type of calipers. With this technology, the caliper has technical features that are generally found only on racing calipers that are machined from billet or forged. All the calipers in the GT | BM braking systems are cast with internal fluid lines rather than with the more conventional external rigid pipe connections. The bleeding screw is invisible therefore it fits better within the overall design and this ensures greater safety and freedom of design. The family of GT | BM calipers stands out for the higher degree of efficiency in terms of architecture and style thanks to the lack of aesthetic limits that are typical of calipers that are cast using traditional methods.
The picture is for illustration only, the actual product may differ.
2-piece brake discs come in 3 different design options of your choice; Type III, Drilled or Slotted discs as shown below.

The Cast Monobloc Calipers are available in either Black, Red, Yellow, White or Fluorescent Yellow colours as shown below.
