The suspension on the M18T Pro pivots on balls all round. On the standard car these were plastic, but the 'Pro' comes with long-lasting nickel plated balls pre-installed into the suspension arms - though plastic alternatives are also provided if you want to lightest setup possible.
The suspension uses double wishbones all round, so camber changes aren't possible, but the same hubs are used front and rear so rear toe changes are possible. The rear suspension is assembled first and Xray supply threaded rods to set the rear toe-in, though plastic fixed-length rods are also included.
The hubs (below) have lugs which push into the the deep recess in the outer pivot balls, and small 2.2mm screws secure them in place.
The drive shafts on the original m18t were plastic, and from what I've heard not really that strong. On the M18T Pro however Xray supply universal joint style shafts for all four corners, machined from the well respected 'Hudy spring steel', meaning they should take any abuse this little car can dish out - and then some!
The axles themselves are long, with flats machined at the ends to locate the Xray-specific wheels. Touring car wheel adaptors are available seperately.
The completed suspension with drive shafts and bearings installed screws to the gearbox from below and above - the long upper screws also holding the gearbox halves together.
With the rear suspension attached, I noticed it wasn't entirely 'free', there was some notable friction in a couple of the balls on one side. I simply pinched the plastic around the ball with a small pair of pliers, which freed things up nicely.
A switch 'pinch' with some pliers freed up the only tight ball joint on the car.
Threaded rods for rear toe settings - a solid plastic composite link is also included for a non-adjustable toe setting.
The front end assembles in much the same way. The front upper suspension arms are 'sided' with a TL and TR (top left / top right) moulded in. The inner rear pivot ball is larger than all the others which lowers the trailing edge of the arms to give the front suspension some much needed 'kick up'.
