2012 Minimum Weight

#221

The big question I have is how best to secure it? I have a couple of Lincoln Navigator rotors I’m hoping to use as ballast but I’m not sure how best to secure it safely.

#222

9.3.13.2.3. Each segment, or stack of segments, shall be fastened with a minimum of two
(2) one-half (1/2) inch diameter bolts and positive lock nuts of SAE grade 5 or better
unless the ballast is mounted using the four (4) passenger seat mounting points and
replacement bolts, and shall utilize large diameter, load distributing washers.

9.3.13.2.4. Holes may be drilled in the passenger compartment for purposes of securely
mounting the ballast and the mounting point may be reinforced for the same
purpose.

Heres my data to add to the spreadsheet.

Drivers door steel replaced with aluminum. Front bumper cover and valance replaced with 2lbs of carbon fiber. I have a gigantic 3 quart accumulator and run 9 quarts of oil. IE front strut bar.

Well now that the car is together…

'89 coupe

A/C gone
P/S gone
HVAC still in place
sound insulation mostly gone in the interior
simple fire bottle
horns still there
Trans tunnel sound insulation still there
all undercoating still on vehicle (its caked on)
.120 thick cage bars
huge battery
full tank
125lbs max ballast
205 lbs with gear on

Pre race 2754

I took a look at what I could take out and what it might weigh at minimum weight I can achieve. I believe if I can fix the fueling issues and run a half tank…

I could get to 2550 pretty easily PRE RACE with driver.

The German definition of a coupe has no b-pillar. IE ford Thunderbird. So we have a two door sedan. If only the the insurance companies used their definition.
