In most locost plans the frame rails between the front tires and the engine are angled inward toward the front.
So wheelbase will change a bit as the suspension moves up and down.

Any beneficial or detrimental effect of this for racing?

Are there any other sport or racecars with angled frame rails and suspension mounting points?

On a locost the front suspension mounts are parallel to the centreline of the chassis so there is no change of wheelbase with suspension travel.

The inboard pickups are parallel despite the chassis being tapering in.

A better example would be the Pagani zonda rear suspension

You must be looking at the wrong book

Would it not be the angle of the pickup points in relation to the horizontal that would have an effect on wheelbase? ie if the front pickup was lower than the rear one then the wheelbase would shorten during travel and vice versa? Or am I missing something?
