[OXO cube]

 The main factor will be how much the car relies on the front wheels. 
I generally tripod my car setups ( if I can ) so the fronts have no function.
Many use the fronts as outriggers, they need to stop the car from tipping. floppy fronts are no good for that. 
Different philosophies.

very interesting alan , its definitely a ponderer 

all the proxies i have entered so far stipulate that the front wheels must touch the track 
therefore my 'tin pot' thinking is that if the wheels are wobbling around this would be detrimental
especially as the car i mentioned doesnt use a podded chassis , so my thinking was ( as you say ) it could tip in corners 
but the aventadore has now thrown another feline into the mix !?!? 

i am so tempted to remove these stub axles and go for a solid one 
but i dont want to damage the wheels/chassis doing so
hmmmmm 

different car maybe the answer
