Ford Racing ABS Installation

[Rob Liebbe]

The more I think about undercar ballast, the more I worry about it. Even if Marshall does a good job with it (I'll reserve my judgement until I see it), that doesn't mean that the next guy to do it will do it properly.

Guys,
I get it.. I'll review the installation and see if any tweaks are necessary... I wanted to build the box, but the other director's said "no". There is a max of 3" tall in the car and to spread 300lbs around would take a BUNCH of floor space.

Interesting idea putting the ballast under the car....I like it! Never occurred to me but the lower the better right? Just watch out for those curbs

Interesting that I thought this was only allowed in AI and not CMC. But looking at the CMC rules again, there isn't anything specifically against it.

352 square inches in steel (roughly 19" x 19" if square)
244 square inches in lead (roughly 16" x 16" if square)


Less power seems like a better idea for Toyos (except at TWS)...

Guys,
I get it..

I for one wasn't trying to "beat you up" about it. So don't take it that I was.

Running wide at T7 at Hallett will drag that "skid plate" over those big rumble strips.
If it doesn't rip it off the car, it's certainly tear up the concrete.

I was following Matt White through there, he pushed wide, straddled the strip and the flying debris was unbelievable.
BIG chunks of concrete ...

I straddled Michael's exhaust last year and it put a huge crease in my K-Member and tried to punch a hole in the rear floor pan.

I'm sure James has seen his share of car parts come through the windshield of his dirt car.

These plates are ABOVE the exhaust, in the rear seat pockets, forward of where the upper control arms used to mount. There is NO way I would ever drag these on the ground. There is at least 10" between the ground and the underside of the plates. This could never be considered anywhere close to a skid plate.

I figured spreading out 80lbs on each side of the car was the "safer" thing than 300# all in one place. Again, four 20# plates per side, each 10"x16"x0.25 thick.


I'm not taking any of this as a personal attack. I understand that folks are concerned with safety (theirs and others).

Didnt want to know that

Sounds like you didn't optimize their location very well then... :-)

That's as good as my Texas Tech engineering degree could get me for right now... There is always time for relocation later.

I wouldn't advertise that too loudly. You used that degree to design tie rod ends... :-)
