I ran into this problem a couple of weeks ago on a 17x16+1 85 degree ZRA S2 which we spec'd with a 92 degree back angle and 4" of dump. Using the shape of the standard side guard as our guide, we opted to get the standard size carbon fiber side guard with the fold down hardware. Because of the combination of dump and the back angle that was spec'd, TiLite drilled the holes in the panel so that it ended up much further forward than we expected (TiLite mounted them to permit the top corner to clear the backrest). The arc of the side guard meets the frame rail only an inch behind the upholstery. Not as much of a problem with removable side guards, but a significant problem if the end user performs lateral transfers since they can't be removed. I suspect this issue is most likely to occur on chairs which have 3-4" of dump combined with a fairly upright back angle.
The side guards on the "
Z9.5" had to go back to TiLite to be re-cut to clear the JetStream Pro.
I'm currently working with TiLite Customer Service to remedy the issue, but I'm sure this is occurring fairly often with their regular upholstery. TiLite really needs to consider redesigning the shape, and possibly size, of the fold down panel to ensure the end user has enough transfer room at the front and less of a gap at the rear (Something similar to the Z9.5's).
The small side guard panel would be 1" below the tire on this particular chair. Hitting the side guard during a transfer can have significant implications. Cutting carbon fiber can be hazardous, so I'm sure they don't want end users modifying them on their own.
End users shouldn't have to pay an additional $275 on top of what is already a $400 option to get their side guards profiled just to ensure they can transfer into their new chair when it arrives.
