The Scaleauto Formula 90-97 Morro Bajo (SC-6251) is a slot scale single-seater assembly kit, inspired by the single-seaters of the 90s. Ultralight body of 0.65 mm, SC-0025b motor with 21,500 rpm and a 6-position suspension system to compete from the very first moment with top-level components.
The Scaleauto Formula 90-97 Low Nose: a competition kit with a 90s soul
The Scaleauto Formula 90-97 Low Nose (reference SC-6251) is an assembly kit designed for enthusiasts who want to build their own slot car and take it directly to the competition track. Based on the spirit of 1990s Formula single-seaters, without reproducing any specific homologated model, it offers a versatile and reliable platform with top-quality materials ready for fine tuning.
Features and highlights
- Ultralight body: thickness of only 0.65 mm, with a high level of detail and the lowest possible weight to enhance track performance.
- Adjustable front axles: allow adjustment of the front geometry according to the type of track and the driver's preferences.
- Reinforced chassis ribs: greater structural rigidity without sacrificing weight, key to maintaining consistency lap after lap.
- 6-position suspension system: optional motor mount fixation at up to six different points, allowing adaptation of weight distribution and the car's dynamic behaviour.
- Front and rear body height adjustment: precise adjustment of the centre of gravity and aerodynamics according to race conditions.

Motorization: inline configuration
The SC-6523C motor mount places the motor in an inline position, that is, perpendicular to the rear axle and in line with the car's longitudinal axis. This configuration lowers the centre of gravity compared to other solutions and favours stability in fast corners, a notable advantage on Sport tracks where precision in the racing line makes a difference.
Track behaviour
The combination of the SC-0025b motor at 21,500 rpm with the 26/10 gear ratio provides a nimble and progressive response, very manageable for both learning drivers and club competitors looking for a tunable platform. The front Grip Zero tyres and rear AS-25 Supergrip tyres offer differentiated grip between both axles, a common choice in competition single-seaters to balance traction with manoeuvrability on corner entry.
Ideal for…
- Slot enthusiasts who enjoy the assembly process and pre-race tuning.
- Club competitors who want a solid and customizable base to work on.
- Drivers looking for a scale single-seater with easily identifiable and available replacement components.
Points to consider
As it is an assembly kit, the car arrives disassembled and requires user assembly. This is precisely part of the appeal for those who enjoy getting to know every piece of their car before putting it on the track. Scaleauto offers a wide catalogue of individual spare parts for each included component, making long-term maintenance easier.
Frequently asked questions
Does this kit include all the necessary components to be ready to race?
Yes, the SC-6251 includes chassis, body, motor, guide, transmission, axles, wheels, and tyres. You will only need the controller and track to start racing once assembly is complete.
What type of track is this single-seater compatible with?
The Formula 90-97 Low Nose is designed for Sport track, the system used by brands like Scaleauto and Slot.it. Check the width of your track installation before racing.
What does it mean that the motor mount has an offset of -0.5 mm?
It indicates that the motor is slightly offset from the car's central axis. This fine offset allows for optimizing lateral mass distribution and improving corner balance.
Can I replace the SC-0025b motor with another Scaleauto motor?
The SC-6523C mount is designed for motors compatible with the Scaleauto range. Check the technical sheets of each motor before making a change to ensure compatibility of dimensions with the mount and transmission.
Does the nylon pinion affect performance compared to a metal one?
The nylon pinion (SC-1010) reduces mechanical friction in the transmission and slightly dampens gear noise. For club use and recreational competition, it is a common choice; in high-performance categories, some competitors opt for metal pinions depending on the regulations.
What level of experience do I need to assemble this kit?
An intermediate level is sufficient. If you have previously disassembled and adjusted a slot car, assembling the SC-6251 should not present difficulties. Scaleauto includes the necessary documentation with the kit.
