For those that are interested, here are the semi-official SM2 rules as
posted on http://streetmodifed.org/sm2_rules.html

Note that SM2 is no more "anything goes" than SM is - it still has
displacement limits and minimum weights (although the weights are lighter
than SM, as one would expect)

SM2 deserves a fair and reasonably level playing field too:

----------------------------------------------

II. PURPOSE

       B. STREET MODIFIED 2 (Street Sports Modified)
              To serve as a membership recruitment and retention tool by 
providing a natural competition outlet for for auto enthusiasts using
              streetable sports cars equipped with drivetrain and suspension 
modifications that are beyond those allowed in the Street
              Prepared catagory, and for streetable sports sedans deemed 
inapproprate for inclusion in Street Modified

III. CLASSES

       B. Street Modified 2 (SM2), 1 class

IV. VEHICLE ELIGIBILITY

           1.All sports cars (2 seaters, and 4 seaters on the SM Exclusion List)
           2.All otherwise SM-legal sedans, excluded from SM due to failure to 
meet minimum weight
           3.All otherwise SM-legal sedans, excluded from SM due to failure to 
meet displacement limits

       V. ALLOWED MODIFICATIONS

       All modifications (subject to the same allowances and constraints) as 
the current SM rules. Note that SM2 uses the exact same ruleset
       as SM, it is the eligibility requirements that differ. The one exception 
is minimum weights:

       Minimum Weights

       All SM2 cars are subject to the following weight limits, by displacement 
and driveline type:

       Category 1 and 2 Cars (2-seaters and underweight sedans)

                        a)    0 to 3.0 litres, forced induction (OHC engines)
                               0 to 4.0 litres, forced induction (pushrod 
engines)

                               Minimum Weight
                               FWD: 1600 lbs
                               RWD: 2100 lbs
                               AWD: 2300 lbs

                       b)     0 to 3.0 litres, normally aspirated (OHC engines)
                               0 to 4.0 litres, normally aspirated (pushrod 
engines)

                               Minimum Weight
                               FWD: 1500 lbs
                               RWD: 1900 lbs
                               AWD: 2100 lbs

                       c)     3.01 to 6 litres, naturally aspirated (OHC 
engines)
                               4.01 to 6 litres, naturally aspirated (pushrod 
engines)
                               0 to 1.5 litres, (rotary engines)

                               Minimum Weights
                               FWD: 1700 lbs
                               RWD: 2200 lbs
                               AWD: 2400 lbs

       Catagory 3 (over-displacement sedans)

                       a) Category 3 cars are to use the current minimum 
weights for SM cars, as published in the SM rules

                       In the case of an under-weight, over-displacement SM 
car, the SM weight limits shall apply.
                       (so in reality, an under-weight, over-displacement SM 
car is not SM2 eligible)

--------------------------

As for the SM2 PAX - I really have no opinion, as the PAX is of no value
other than raw entertainment, and basing anything important on something as
intrinsically flawed as the PAX index is pure comedy. However, having said
that, I rather strongly doubt that SM2 will be faster than AP. Slicks,
better chassis allowments, and minimum weights you are allowed to strip the
car to meet trumps engine power in spades.
