Ultimate Racing have introduced the latest version of the Compak Clutch, the V3. Keeping the same philosophy of a high-performance mounted clutch, all its parts have been redesigned to guarantee better performance and reliability. The flywheel is 34mm diameter and the aluminium shoes have been redesigned, increasing the contact surface with the clutch bell, improving performance, durability and preventing it from wearing the spring and causing possible spring breakage due to friction. The springs has also been redesigned to adapt it to the new shoes using a very heat-resistant material and thus avoid possible breakage. The clutch is available as a complete and assembled set including flywheel, aluminium shoes, springs, nut, cone collet and shim. They also have a combo with the UR Ventilated Z13 clutch bell with bearings.
Ultimate Racing have introduced the follow up to the successful M3X engine with the release of their new 3 port .21 Off-Road Ultimate MXS Ceramic Competition Engine. Like its predecessor, the MXS is made by O.S. Engines and it’s based on their square stroke Speed B21 Ty Tessmann II edition engine but has some modifications on the crankshaft as well as on the back plate to improve performance. This engine has more power and returns to idle way better than its predecessor. The cooling head has been redesigned and while not as low as the B2102 lower profile, it is lighter so it keeps the center of gravity as low as the B2102 but improving its performance on high temperatures. The backplate has been updated to improve the gas flow going to the piston and improving engine efficiency and performance. The crankshaft of the MXS is an evolution of the DLC B2102 but with two balanced tungsten in order to increase the inertia to rotation. Also available as Team Edition and combo with the EFRA 2141 or 2142 pipes.

New from Ultimate Racing are these useful 1/8 offroad insert rubber rings. Manufactured to fit into each of the insert’s grooves, once fitted the insert is practically fixed to the rim. In this way, the insert is prevented from moving laterally, improving stability in fast corners. It also prevents the insert from ballooning making the car much more stable under acceleration. They can be used on most inserts, wheel brands and compounds, but their effects are greatest on soft compound tires. Depending on whether you want the insert to be more or less fixed, they can be used in all three grooves, in two or only in one. They are sold in bags of 50 pieces so that you can assemble from 4 to 12 complete cars depending on the amount of rubber bands used per insert. Once the life of the tire is over, they can be reused as many times as you want.

This exhaust system comes supplied with the pipe, 2 medium springs, 2 long spring and 2 manifold gaskets.
Ultimate Racing have introduced the ‘Team Edition’ version of their previously released M5S Ceramic engine.

From Ultimate Racing for the Mugen MBX8 are some new aerodynamic attachments. First up is this clear lexan front upper arm wing, an aero option that attaches directly to the front upper arms. This tuning option helps to increase front end grip and traction at higher speeds, while helping to improve the front/rear balance in the jumps. These wings are feather light and include lightweight machined mounting brackets that create a strong and lightweight mount for installation. The front wing replaces the front nose-cone on the vehicle with a front wing design that has shown to produce enhanced steering characteristics. The front scoop includes 2 pieces per package, so a driver has enough to outfit their nitro and e-buggy with the same package. This wing provides increased feel and sensitivity in the larger sweeping sections and helped jumping attitude in the tricky jump sections.
