Depends on the style and offset of the Forgeline wheel. Some will likely fit, some won't. You have a much better chance of the 19 / 20's fitting than the 18's. Offset is important here too, not just wheel size.
I can tell you that the standard SX3 Forgelines made for Gen II in 18 inches, won't fit on SRT-10s. The bolts that hold these wheels together will touch or hit the cross over brake line at the bottom of the brake caliper.
The VR1's pictured above will likely fit if the offset is correct.
