The IPK group’s brand, Formula K, presents its new Evo 30. The chassis isn’t a new homologation, but it does have several new features worthy of mention, starting with the new STR.V2 front braking system

The Evo 30 chassis greets the 2018 season on the heels of a significant restyling by the technicians at Formula K, a brand that, along with Praga Kart and OK1, belongs to the IPKarting group. Despite this not being a new homologation, there is nonetheless no shortage of modifications. The chassis has a classic design, the tubes are all 30 mm, and the welding is performed manually by specialized technicians, as always at IPK. The rear, however, presents an important novelty: open bearing flanges. A modification that provides greater sensitivity to variations in rear setup, such as changes in axle hardness. Another important advantage is the possibility of dismantling the axle more quickly.
No changes, on the other hand, in the front, where for the adjustment of Caster and Camber the CCS system is confirmed, allowing a variation of the two angles in a range of 2 degrees positive and negative, and 4 if the device is used in the lower part as well.
Confirmed as well is the support for the steering column: a casing fixed to the chassis to which is attached the adjustable heel rest, offering different positions depending on the driver’s stature. An optional pedalboard is also available for the smallest drivers, to bring the pedals even closer to the seat.

The brakes were revised both in the rear and in the front, which is where we find the most important new feature, the STR.V2 model destined for the KZ categories. IPKarting’s technicians have designed a brand new caliper with four tiny pistons that aims to improve the modulability of braking. As confirmed by Cash Van Belle, the head of IPK’s racing team, the four tiny pistons distribute the force exercised by the pad on the disc over a greater area, making it possible to eliminate jamming in throttle-off and give the driver greater control when entering a turn.
The callipers are machined from a single block using C.N.C. processing. Particular care has gone into developing the shape, designed to improve the cooling of the disc and the removal of dust created by the pads.
The brake discs have also been rethought in order to improve brake pad cleanliness. The front brake discs are 149 mm in diameter, floating and self-ventilated. In the rear braking system, known as RBS.V2, we now find the possibility of choosing between two different diameters: 187 mm, the standard measure, and 195 mm, an optional. The rear calliper has been made more robust by a reduction in bending points, but without modifying the weight.
