1. All allowances in STS would carry over,
including street tires, rim restrictions, etc.
4. Only factory limited slip differentials (LSD)
are allowed on AWD vehicles, as defined in Section
12.4. For 2WD vehicles and AWD vehicles that did
not come with any type of limited slip differential (including center differential or
transfer case) a single aftermarket LSD may be
9. Additionally excluded cars: BMW M3 (E36 and
E46), BMW M5 (all)."
Item 1 says all STS allowances carry over, which
says only factory viscous LSDs may be used. This
is the rule that kept the E30 M3 and 325is out
of the Street Touring classes.
Item 4 only addresses the differential on AWD
vehicles and for 2WD vehicles that did not come
with a factory LSD, but does not mention anything
about 2WD cars that came with clutch-pack style
LSDs like the E30 M3. So with the STS carryover
rules only allowing viscous LSDs, and these new
STX allowances not addressing 2WD/RWD cars with
factory clutch-pack style LSDs it looks like the
E30 M3 and 325is can't run in this new class
either. Yet they don't specifically exclude it
like they do the E36 and E46 M3. I'm trying to
find something in the rules that would allow
the cars to run in that class, but can't find
a way to defend it against a protest.
I think a clarification letter needs to be sent
to Howard Duncan !
