stock rear suspension rules please point me to the post i did not find in search; otherwise...
first came the lca relocation brackets moving the mount away from stock position on the rear. thats ok
then the tq arm can be mounted to the cross brace instead of the transmission and thats ok.
then i see a tq arm adapter bracket that pretends to be a factory mounting location on a ford 9" and thats ok
next i see that the sway bar does not have to mount to the body or on the rear in the factory location and thats still ok
next i see brackets to move the bottom of the shocks to keep them from binding....
now i see panhard bars not being fastened to stock location....
is it right or wrong to think to be 'stock suspension' now a days you just have to actually use a tq arm period
just trying to gather information in case i decide to be legitimate s/s
next year i bet would be many more than one 'exhibition' moser tq arm car at the lsx race for exampe. will they be allowed?
thanks! i dont want to put money in the wrong place

There was NOT a stock suspension rule at the LSX race last year.
RWYB as long as its GM ans LS based pretty much...
SUSPENSION
Aftermarket K-members permitted
Fully tubbed or mini tubbed wheelwells and notched frame rails permitted
Factory rear frame rails required in OEM location
Wheelie bars are permitted
Stock type suspensions, ladder bars and non-OEM 4-links permitted
Coil-overs permitted

I think what gets away from stock suspension is when you run a wishbone instead of a panhard bar, or if you relocate the lower control arms off the factory moutning position.
At least with a 3rd or 4th gen f body car, now if you get into other cars that had leaf springs and whatnot, I have no idea where the line is for that stuff.

The guys on here who moved the panhard mounting point weren't claiming stock suspension anymore. As far as the rest idk. I know most "stock" suspension classes around here say you can run any parts that are a bolt on part. That covers the lcas, panhard, and torque arm(if you run a version that bolts to the body still and just relocates the mounting point). I guess that could also cover madmans shock piece that turns them 90 degrees so they don't bind and if you had bolt on lca relocation brackets.
I'm sure any NHRA or IHRA class has everything spelled out exactly in the rule book if your looking to run in one of those classes.

We race alot of stock suspension type races and the main thing they want to see is:
Torque arm on 3rd and 4th gens (no ladder bars or 4-link)
Lower control arms mounted in factory location on car. (not necessarily on the rear end)
mini tubs only- stock frame rails, minimal notching ok.
We ran a panhard bar, but a wishbone was perfectly acceptable on other cars in stock suspension.
The fact of the matter is: No one is going to have a tape measure out while you're going through tech, they just don't have time- and they really don't care. It's all about "The spirit of the rules".

And thats all I got to say about that. 
If you're racing ORSCA or some other "outlaw" style sanctioning body- yes, the coil overs are legal. Primarily because they are needed on Mustangs to keep the tires under the car, and one couldn't say coil overs are legal on mustangs but not F-bodys.
