Beware of CSR Performance

[lstanford]

Just put in a dispute with your credit card company. They will reverse the charge and credit your account.

Well its gonna be hard to comply with the new flex plate shield rule for many of us with stock transmission tunnels, no SFI transmission case option and no CSR shield. Hate to say it, but were gonna need removable tunnels in Stock to comply with the new rule given lack of product availability.

I sure wish someone else would start to manufacture the carbon fiber shields!

not a new rule...

General Regulations Section 21, page 17

2:14 TRANSMISSION, AUTOMATIC/NHRAACCEPTED
All cars running 10.99 (*6.99) seconds and quicker must have
an NHRA-accepted locking-type dipstick on the transmission,
and dipstick/filler tubes must be securely fastened (i.e., bolted,
aircraft clamped). Wire ties, hose clamps, etc. prohibited.
Any non-OEM automatic floor-mounted automatic transmission
shifter must be equipped with a spring-loaded positive
reverse lockout device to prevent the shifter from accidentally
being put into reverse gear. Functional neutral safety switch
mandatory. All transmission lines must be metallic or highpressure-type hose.
All vehicles running quicker than 10.99
seconds (*6.99) or faster than 135 mph (except some Stock
and Super Stock classes as noted under Class Requirements)
and using an automatic transmission must be equipped
with a transmission shield meeting SFI Spec 4.1 and labeled
accordingly. (“Blanket”-type shield, appropriately labeled as
meeting SFI Spec 4.1, permitted.) All non-blanket-type shields
must incorporate two (or one, per manufacturer’s instructions)
3/4 x 1/8-inch straps that bolt to the shield on each side and
pass under the transmission pan, or transmission pan must
be labeled as meeting SFI Spec 4.1. Permitted in all classes
where an automatic transmission is used.
Comp, Super Comp, Super Gas, 9.99 or quicker E.T. cars, and
135-mph or faster E.T. cars using an automatic transmission,
Lenco Drive, or BRT must be equipped with a flexplate meeting
SFI Spec 29.1 and covered by a flexplate shield meeting SFI
Spec 30.1. Transmission that can utilize a high-gear transbrake
must be supported by the use of two momentary buttons
(one to arm the system, second as the main transbrake). Air
shifter bottles must be stamped with DOT-1800 pound rating
(minimum) and be securely mounted (i.e., no tie wraps or hose
clamps).

Stock/Super Stock - Beginning January 1, 2024, SFI Flexplate mandatory on all V8 vehicles.

long overdue. too many old guys still running 50 year old flexplates and others chinese junk.

[Billy Nees]

The 50 year old flexplates aren't the problem and neither is the good stuff (ATI, Meziere). It's the Chinese stuff.

[DG]

My mistake, I confused the new SFI flex plate rule with the old 9.99 flex plate shield rule. Since I am moving to A/SA, their both new rules for me to comply with.

[FLEMING]

Ok, i knew about this.. I just thought it had gotten changed for the slower class cars as well..Doesnt effect me lol
