also can i prevent over centering by limiting angle, eyeballed with bump stops on lca? i will not be relocating rack, so offset rack spacers are my other option.

It sounds almost like you're unwilling to make some of the compromises required when one is in search of 'big' angle on an S-Chassis. In any case, improving your inner frame rail clearance is pretty straightforward.
Depending on your wheel to firewall clearance (move the wheels through the steering arc at various levels of suspension compression and measure the closest point between the wheel and firewall) you may be able to use a spacer to gain a small amount of clearance between the inner rail and your wheel, although since the spacer is moving the wheel away from the rail at an angle (and towards the fire wall) you won't get much clearance out of this method.
The best solution, as Motary suggested above is to lengthen the lower control arm by some amount (probably 20-25mm) to move the steering axis out which will effectively move the radius defined by the outer most point of the wheel away from anything that it could come in contact with in the insides of the wheel well. This might also neccesitate a longer tie rod and more than your desired amount of camber, so you'll need to look at your entire setup and see what this could interfere with.
As far as steering over centering, you could get offset rack spacers if you wanted, or offset steering rack bushings, or use both. it's kind of up to you. If you don't want to do some sort of insane cross-member mods then a combination of offset rack spacers and bushings is the way to go.
You should also look at your wheel tire combination in itself. Depending on what tire you're running, you may be able to get a 'better' tire that's actually narrower...

The way the FD rules are written, or at least last time I read them, anything outside of the chassis/unibody pickup points may be modified. In this case, struts, suspension arms, knuckles are essentially an 'unlimited' class as long as they connect to the stock mounting location.
As far as the RWD TC business, there was/is some clause in the FD rules that allow for an 'AWD Chassis' to be converted to RWD for competition use. In the case of the TC, Scion argued that it shared the same chassis as the Toyota Avensis, which came in AWD, thus allowing for an 'AWD TC' to be converted to RWD.
