My FC 'pushes' a little with equal air pressure front and rear. I'm getting conflicting opinions on whether to drop a couple of pounds pressure from the front tires, or the rear tires, to minimize the' push'.

How hard is it to try both?

Ideally you want whatever air pressure gives the tire the most grip. Once you have established that and the car still pushes leave the front alone and keep adding pressure to the rear until the car balances to your liking.

 

It depends on what the pressures are now. Put chalk or white shoe polish on the sidewalls of the tires so you can see how much they are rolling onto the sidewalls and adjust it untill they are just running onto the edge of the tread, then adjust from there. From there, raising the rear pressure is probably the best bet.
