Hi,



It's hard to read between the lines with SCCA rules and I know it's highly
discouraged.

So I would like to find out what the ruling would be about updating a Pre
99 Ford Mustang World Challenge GT car.



Independant rear suspension was offered in 99 and later - can it be
installed on the earlier cars without imposing an additional weight
penatly?


Quote:

9. Cars that come with a solid rear axle, or trailing arm suspension are
permitted an after market or fabricated rear suspension. Cars with an
altered rear suspension pick up points must add 50 lbs. Cars with live
axle RWD may reduce the minimum weight by 50 lbs.



Engine Set-back - the pre-99 Mustang seems to have been left out of
this while the Camaro-bird was not.

Quote:

Cars may modify, or replace, motor and gearbox mounts provided that
the engine is located in the specified location. This includes the use of
“torque plates”. All engines will be mounted in the stock position unless
otherwise specified.
Engine Setback Allowance:
1. Cadillac CTS-V and Pontiac GTO - 214mm from stock location (78mm
from firewall)
2. Ford Mustang (99-04) 4” from stock location
3. Ford Mustang (05-06) 8” from stock location
4. GM F-Body (93-02) 4” from stock location



Firewall - If the engine is set back, I am presuming that the original
firewall must also be set back as per the rule below;

Quote:

The OEM firewall between the cockpit and engine compartment shall be
intact to prevent the passage of flames from the engine compartment to
the cockpit. Any holes in the firewall must be of the minimum size for
the passage of controls and wires, and must be completely sealed.




Your thoughts are appreciated. Thank you..         & nbsp;

I have just posed these questions to http://crbscca.com as well ..  It's my understanding that they meet the first Tuesday of every month.

I will update this thread when I get the information.

 

Thank you.

Regards

Hi Guys,

Looks like I got a couple of answers in the last FastTrack;

#1228 (Randy Van de Loo) Updating / Backdating within STO In 9.4.1.B.6,
add at end of first paragraph: “Where an engine setback is allowed, the
OEM firewall may be modified only enough to accommodate the engine
set back.” In 9.4.1.B.6, correct item 2 by replacing “(99-04)” with “(85-
04)”.


So I believe that this will now read;

Cars may modify, or replace, motor and gearbox mounts provided that
the engine is located in the specified location. This includes the use of
“torque plates”. All engines will be mounted in the stock position unless
otherwise specified.

Where an engine setback is allowed, the OEM firewall may be modified
only enough to accommodate the engine setback.


Engine Setback Allowance:
1. Cadillac CTS-V and Pontiac GTO - 214mm from stock location (78mm
from firewall)
2. Ford Mustang (85-04) 4” from stock location
3. Ford Mustang (05-06) 8” from stock location
4. GM F-Body (93-02) 4” from stock location
------

I guess I will have to write to them ((AGAIN)) to find out about the
updating of the rear differential on pre-99 Mustangs to allow IRS without
additional weight penalty. If there is a weight penaly - then maybe just
go ahead with the modifications and eat the 50#...

------

I just don't want to spend a lot of time and money to create something
that will land me in trouble while in the tech-shed...

------

Thanks guys.

Regards - Randy
