That is 944spec.

(The Cup does not allow much extra for the car selecting SCCA rule set...does not need much since the Cup's minimum weight for SCCA rule set car is 2800.)

I was almost buying a ready spec car, and listing parts missing to run in SCCA or the Cup, and decided not to, since there are too many items were missing. In addition, they allow to have welded A and B pillars, up to 10 mounting points to compensate minimum cage structure.

The below is the instruction posted by the director of 944spec on another forum.

He is preparing the car to 944 spec (SP1 rules) so there are number things he CAN'T do.

1) Mirrors must be stock on the outside. IE full flag mirrors, inside can be anything
2) Body panels must remain steel
3) Bumpers must be stock
4) No lexan allow in windshield, rear hatch or qtr windows.
5) Cutting away large bits of the metal shell is really frowned upon (don't do it)
6) Stock gauges must remain.

What he can remove
1) Everything that is bolted down and is not needed to operate the car
2) All coatings both inside the car and under the car
3) The 40lbs of heat shielding between the engine and firewall.
4) A/C and all parts
5) heater and all associated parts
6) Body mouldings including front & rear bumper pads
7) powersteering and all related parts
8) Door glass and all related parts. (Please keep the stock door bar for safety)
9) Lightweight battery (instock location only)
10) Any bits of wire harness that was used for removad components
11) All misc brackets used to support removed parts
12) Windshield wipers, motors & linkages (BTW... you can races safely with just a driver's side wiper)
13) All headliner and or sunroof parts (must fix in place stock roof panel)
14) rear hatch motor and related parts (use key to open rear hatch)
15) hood and hatch lift shocks
16) Replace heavy cast iron headers with ligher stock tube headers
17) Cat replaced with Test pipe
18) Replace muffer with straight pipe (must meet local sound limits however)
19) Driver's seat only with Aluminum Side rails
20) 1.75 x .095 DOM custom cage with close eye paid to not "jungle gym" the car with 500 tubes.
21) "Late 944" smaller lighter starter motor.[/b]
