| I have to ask why you're running FSP, but anyways....
See SP rule 15.2.C, i think that clears the tie bar (it calls it a strut bar, but it does meet their definition of between suspension mounting points), but the Xbrace is almost always a no go. Its not necessary anyways.
I didn't read the rules superclosely, but if you can't connect the sway bar mounting points, that means that brace plates like Progress and neuspeed are out, although I highly doubt anyone will raise a fit about something like that on a local level. |
