so I found this, but I still dont know if its legal or not(not clear enough for me)?
Subframe mount bushings may be replaced, but must attach in the factory location(s) without additional modification or changes. Sub- frame position may not be changed. The amount of metal in a re- placement bushing may not be increased relative to the amount of metal found in a standard bushing for the particular application. Solid metal bushings are specifically prohibited.
Longitudinal (fore-aft) subframe connectors (SFCs) are permitted with the following restrictions:
1. They must only connect previously unconnected boxed frame rails on unibody vehicles.
2. Each SFC must attach at no more than three points on the uni- body (e.g. front, rear, and one point in between such as a seat mount brace or rocker box brace).
3. SFCs must be bolted or welded, but welding must be to the OE subframe stampings, not to the floor pan in between.
4. No cutting of OE subframes or floorpan stampings is permitted. Drilling is permitted for mounting bolts only.
5. No cross-car/lateral/triangulated connections directly between the driver’s side and passenger’s side SFCs are permitted. Connec- tions to OE components such as tunnel braces or closure panels via bolts are allowed and count as the third point of attachment. No alteration to the OE components is permitted.
6. SFCs may not be used to attach other components (including but not limited to torque arm front mounts or driveshaft loops) and may serve no other purpose.
