What's the weight of the Jackson Racing Dual Radiator/Oil Cooler?
What's the weight of the stock radiator?
Thanks for any help.

#26786 FRS/BRZ Dual Radiator/Oil Cooler Clarification
The STAC is recommending an explicit allowance to utilize combination radiator/oil coolers which are
available for multiple popular cars within the Street Touring category.
Modify 14.10.L as follows:
14.10.L Engine cooling radiators may be replaced with alternate parts subject to the following
restrictions:
1. Radiator core dimensions (width, height, thickness) cannot be smaller than the standard part
2. Radiator must mount to OE radiator mounts
3. Fluid capacity and dry weight of the radiator must be no less than that of the standard part.
4. A replacement radiator may contain an integrated oil cooler provided the portion of the radiator
that is utilized for coolant conforms to the remainder of 14.10.L.
5. Installation of an alternate radiator may serve no other purpose (e.g. to allow a cold air intake
passage).

Given the capacity of the radiator is larger on the coolant side + oil, I don't think you'll have any issues with the weight being any less
