Made for the Centro C4.2 converted Team Associated B4.2 buggies is this rear suspension kit from JConcepts. The set targets 3 key areas where the C4.2 could do with improvements. In stock trim the C4.2 includes a moulded rear bulkhead which is highly flexible and a target to damage in severe crashes. The JConcepts suspension kit includes an all CNC machined aluminium version which has been trimmed, narrowing the stance allowing more room for narrow rear pivot camber link adjustments. The bulkhead is available in blue or black colour and has silver chamfered edges around the border and inner cut-outs. The tucked design, trimmed shape and pocketing give the racer an extremely durable yet light-weight piece.
Next up is the 4mm carbon fibre shock tower that has all the necessary adjustments including the standard outer (C4.2) camber link positions and the newly added inboard camber link holes to accommodate a narrow pivot rear suspension. The shock tower includes an added rib to strengthen the part where appropriate and while allowing big bore shock and transmission clearance where necessary. The upper shock mount positions have been relocated to allow for proper rear suspension droop while all holes are designed on an arc to minimize droop changes during setup changes.
The final touch to the assembly are the aluminium rear wing mounts. The stock wing mounts place the wing extremely high on the vehicle, raising the centre of gravity and increasing the pendulum effect of the rear-end. The JConcepts wing mounts place the wing more than 7mm lower than stock and have been spaced closer to accommodate the more popular wings on the market, allowing a more interchangeable wing between the B4 and C4 vehicles. The aluminium wing mounts are light-weight, durable and set the wing at just the right height giving the vehicle a more natural rake in appearance. All additional 4-40 hardware is included to make the conversion a snap. All parts, the bulkhead, shock tower and wing mounts are also available separately.
