Fenix Racing sphere diff and Upper Arm Mounts

Fenix Racing has announced details of two new items that feature on the new G56.2 Pro10 chassis it released last week, the new Sphere Differential and new Upper Mounts.  The Italian manufacturer took advantage of the releasing of the new G56.2 to rework their Pro10 sphere diff.  As they did with the Pro 10 Gear Diff, in the Mk2 version, they’ve a complete new right hub, with the main bearings distance almost doubled, to ensure better trueness.  They kept the thrust bearing to the diff, as well the gr.5 Titanium axle (a carbon fibre one will be released later, as option), 5 belleville springs to ensure a proper force over the spheres.  Also new are upper arm mounts that will fit the F1 Mistral 2.0 and 3.3 as well G56 and G56.2.  The new upper arm mounts are machined from high-quality 7075 aluminium and they greatly reduce play and unwanted flex, resulting in a more precise feeling of the car on the track.  The newer version allows you to get some extra caster angle in an easier way, compared with the old ones.  It’s just enough to move the 1mm shims back or front to get some more caster.  Black anodised for wear and look, they come in pairs including all necessary hardware.
