Relation between wheelbase and BB-height for handling/cornering

Does a shorter wheelbase allow for lower BB heights in terms of turning/cornering? My logic is that a shorter wheelbase (say 950mm vs 1050mm) allows for a smaller turning radius, and in theory shouldn't require as much steering input or, importantly, leaning into turns to accomplish the same turn that a longer wheelbase bike would require. Can anyone support or refute this idea?

Background: I got a custom 650c track bike made recently, but they built it around the measurements of a sort of wonky 650c fork (it's about 15mm longer axle-to-crown than all other 650c forks on the market). I've replaced the stock fork with an old 650c Litespeed fork since I wanted a brake drilling, but then noticed my BB drop to a height of around 272mm (from 280mm, which is what I requested and pretty standard for track bikes and velodrome use). This bike will be used for the street though and I'm a little worried how this lower BB will deal with pedal strike (preferably before trial and error). This bike also has a smaller wheelbase than all the 700c track bikes I've used, about 915mm instead of the 950-970mm of previous rides.


Anyways, any insight appreciated
