Do you have coilovers? If so, how lowered are you?
The 235/40 helps a little with clearance on some coilovers and has a smaller sidewall which should provide a stiffer sidewall (comparing the same brand/type of tires).
While the 235/45 is closer (I believe) in overall diameter to the stock tire and usually cheaper to buy (more options).
