The frames are made with different types of pipes (always in CrMo alloy steel) welded exclusively by TIG with the addition of dedicated alloys in order to obtain the maximum compatibility / continuity of the materials used and for maximum strength/resilience of the same.

This constructive activity (consisting for the frame in the acquisition of bar tubes from certified suppliers, in the cutting, in CNC bending and in the heading of the same – with particular attention to the precision of this last operation with maximum tolerances of 0,1 / 0, 2 mm., in the positioning of the single components in masks of a particularly rigid type and with absolutely rigid fixings and in TIG welding of the same ones in an inert atmosphere) led to the homologation of the NASCART S chassis (CIK FIA No. 024 – CH – 66) in the cat. KZ2, OK, OKjunior, in addition to the construction of other racing frames.Moreover all the frames benefit from the independent adjustment system of the CASTER and CAMBER angle (patented at the time by DFM srl) which ensures the maximum possibility of “setting”the chassis.

Same constructive / executive system for the “force” components of the frame such as the stub axles  (with the acquisition of particularly resistant alloy steel bars, CNC turning of rods and barrels, head ing , positioning in dedicated masks andTIG welding of the same together with the drive plate and brake caliper bracket.A braking system of particular power and progressivity optimized for the DFM product, a combination of front, side and rear protection of excellent quality, durability and ergonomics and finally a series of durable decals with a strong aesthetic impact complete the DFM Racing chassis. Camber / caster adjustment elements, spindles with multiple angles, composite seats, a wide range of axles, hubs, magnesium rims, are the accessories necessary for the correct adaptation of the vehicle to the progressive requirements in competitions.
