This is the final result of guide replacement in the Alfa Romeo 8C 2300. You can see the white reference line of tyres contact with track surface (left car). On right car I’ve drawn the lowest point of the wheels because they don’t touch the track, there is a gap of about 3mm.
Comparing the relative heights of blinking lamps (upper pic, top lines) you could notice the real front axel ride height difference afterwards (L) and beforewards (R).
As the front wheels axel has a vertical play of about 7mm, the height difference between axels is less pronounced but the relative position with mudguards is clearly more natural and nice-looking.
Moreover, you can observe the car nose inclination apparent difference (R). This is due to front ride height have been lowered, mantaining rear ride height, and balancing that ugly inverse slanted car whose front wheels didn’t touch the track.
Soon you can enjoy the Scalextric Alfa Romeo 8C 2300, 4 times winner of 24 Hours of Le Mans.
