Just checked my '18 SR5 Premium, and the OEM springs have one and 1/2 more coils on the right (passenger) over the left (driver) side. Thus, the gap between the right coils is less than the left coils. When I installed my RC spacers, I was careful to do only one side at a time, so I didn't get them mixed up. And my 4Runner is level (I measured it after the spacers).
My conclusion: the space between the coils is not important.
The factory puts different coils at each corner depending on trim level (SR5, TRD, Limited) and the options installed. If you look at the Toyota parts web site, there are a number of different part numbers for each corner.
