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 SPL Front Lower Control Arms (FLCA) provide roll center, camber, and track width adjustment for the Shelby GT500 and 2020 GT350. Using a mixture of billet aluminum, stainless steel, chro-moly steel, and titanium results in strong, adjustable arms that are 2.0 lbs lighter than stock arms.
The ability to run more negative camber greatly improves the peak lateral grip available, dropping several seconds off of lap times when tested on the Vorshlag Dark Horse. This is especially important with better tires and a must-have for anyone looking to prevent excessive outer shoulder wear (and heating) on their tires due to a lack of camber.
The lower control arms come with a ride height sensor bracket to maintain factory ride height sensor location, regardless of length of the arm to keep the Ford chassis electronics happy.

Install Instructions
IMPORTANT INSTALL INFO
Ford made numerous variations of the front knuckles across the S550 Mustang and Shelby line-up. These knuckles vary across nameplates (Mach 1, GT350, etc), years (2019 vs 2020 GT350), and even options (Handling Pack 2, etc).
Each knuckle variant may have different conical tapered seats where the front control arms mount. It is VERY IMPORTANT to verify the supplied conical tapered spacer fits snuggly into the knuckle, has near zero lateral end play (as-in it will not rock within the bore), and seats fully into the knuckle when installed at the proper torque value.
If you need clarification or feel you may have the wrong spacer for your Mustang, then please email us.
Feel free to contact us at info@mlperformance.co.uk should you wish to double check!
To ensure the part(s) you have ordered fits your vehicle, we run a compatibility check prior to dispatch. We can do this either using your registration number (UK) or the last 7 digits of your VIN. Simply enter your car details prior to checkout.
