Infinity IF14-2 touring car kit

Following a couple of teasers Infinity have finally unveiled their new IF14-2 electric 4WD touring car kit. Building on the IF14 the second incarnation will feature a new drivetrain layout that sees the spur gear being moved to the front of the motor, as the latter remained in the same position as on the IF14. The layout was choses to create a balanced driving feeling, on and off throttle, and to enable the car to run at a constant speed throughout the race. Newly designed suspension arms have a new system incorporated, which makes it possible to fine-tune the shock lever ratio. The new system – that uses inserts for the shock tower and lower arms – coupled with the newly designed shock towers, make it possible to change the shock lever ratio without changing the shock mounting angle. In this way, by changing the shock lever ratio, drivers can change the spring rate, which subtly affects tyre performance, without changing shock springs. With the IF14, when changing the mounting width of suspension arms, and the mounting angle of the shock also changed. With the IF14-II, however, setup is much simpler. Drivers can now adjust the suspension geometry without changing the mounting angle of the shock.

Also in the suspension department, the total length of the newly designed USP shock is 3.5mm shorter than on the original IF14. The USP shocks greatly help to lower the centre of gravity of the chassis. To keep the oil capacity and the shock stroke to a maximum, the shock pistons are secured with special flush fit counter sink screws. With the flat piston top, sufficient shock uptravel at full stroke and sufficient oil capacity are maintained for stable driving performance. The newly designed resin centeew pulley is larger, now 21T, offering better drive efficiency and minimising belt skip. The axle layshaft supported by the motor mount with a cantilever uses three ball bearings and contributes to increase mounting rigidity of the centre pulley and the spur gear. The suspension mount on the IF14-II is now independent, separated from the lower bulkhead. They mount directly to the chassis, increasing stiffness around the front and rear bulkheads providing a more direct feel when driving. For the IF14-2 the separate-type suspension mount concept is employed again. By adding special shims between the suspension mount and the suspension block, finer geometry setting can be done easily. The steering Ackermann can be adjusted by replacing steering plates, which makes it possible to set up and adjust steering characteristics according to track condition. The kit is set for a release in early April.
