Weight of Race Car


#61

Everyone is carrying a spare? Seriously? My car isn’t quite ready yet but I sure as heck wasn’t planning on having that kind of dead weight in the trunk. I don’t mind mass between the axles but the trunk?

I’ve removed a lot of weight… hope I make the minimum without having to add stuff back in!


#62

Weight behind the rear axles is not a problem. Anything to get the weight off the front is good because these cars get nose-heavy.

Here’s my solution about weight: if you suck, no one ever weighs you!:wink:

Yeah, you’d be in trouble if you were Danica. Because I’d have a big woody all day at the track and try to score with you after drinking too much beer with Al and Travis.

This same thing would happen if you were a dude that had long hair the color of Danica’s

Come on! :angry: Give Sasha a break. He doesn’t discriminate between hair colors.
Hell, I don’t think he’s even care if you had hair… after a few beers

Lol we’ve got 3 Scott’s and a Scotty in this thread.

If everyone’s got ballast and/or a spare tire, couldn’t everyone remove them and still be fair? If there were people who didn’t have ballast or a spare, or stuff like sound deadening, and they were barely making 2750 then I could understand it a little better


#68

I have no qualms with the 2750 minimum weight, my contention is that the ballast rules should be freed up a bit. If you remove the 50+ pounds of asphalt from the trunk (which we did, Per said his impetus for doing so was to treat the rust that was forming underneath), the only place you can add it back is in the passenger footwell. Those who are able to retain the asphalt in the trunk gain a great deal more weight on the rear of a car that tends to be nose-heavy.


#69

Put an heavy OEM wheel and tire in the spare well. That will make up for most of the asphalt removed.


#70

I’ve got both and I’m still light.

Yeah, my current plan is to find a massive junkyard steel spare wheel / tire and fix the problem that way. Had some fun with cross weights last night, too; another update to come on the GRM site soon.


#72

It would be nice to just have a minimum weight not the restriction of location or amount of ballast.


#73

Weight in the trunk is definitely not the same as weight between the axles. I know this car is light in the rear, but putting weight behind the axles and increasing the moment of inertia isn’t the right way to fix it – not for racing.

Yes, I vote for increasing ballast allowance for the passenger compartment! :slight_smile:


#74

Tell that to the Porsche 911 guys!


#75

:laugh: True! But with such a light front end, rear engine cars have a different set of dynamics to deal with.

Only front-engine, front-drive cars are worse for racing. But anything can be made to work, right? Props to Porsche engineers for keeping the 911 on top of the heap for all these years.


#76

It would be nice to get an official ruling on these things…


#77

Officially it’s whatever is in the rules. Rules don’t get changed very often, but we have vigorous and mostly futile debates because it brings us so much joy between races.

I don’t want to beat a dead horse, but I would really like to hear an official’s opinion on this. I really am in favor of modifying the ballast rules. It looks like I’ll be running maximum ballast and I still won’t make the minimum weight.


#80

How about building the car first, weighing it, and then try beating the dead horse?
