2021 SS/GT rules & ClassRacerInfo

[Dwight Southerland]

I am researching to see what information really needs to be displayed. With the weight rule as it currently is written, it is hard to judge what would be a minimum and maximum weight race car combination to display.

Would 500lbs. up and down be enough?

Looking for feedback and opinions.

Thanks.

Dwight,
As you know, I have the Caprice in SS/PA and will be able to run in GT now. My old ship weight is 3925. I have been running at 3570 on a 3515 minimum. I can easily get the car down to 3300 with me in it. There has been no gutting of the car, all the power windows and seats still in there. I think in this case you would be looking at 700 lbs. With that being said, I don't think I could get it down to the 14 lbs. minimum.

I think I can get my 91 Corvette up GT/H at 2780 whereas SS/I I'm at 2870. I realize that it would not be a good move but would make my index go from 10.55 to 10.35 if I wanted to slow it down. The ship weight is 3193, so about 413 lbs. in this case.

thanks for all you do for this racing community!!

Wow, I was thinking +/- 500 was more than adequate but Ernie proved me wrong. In any case, I don’t think I can get below shipping weight by more than 300 but appreciate all you do!

I would think with this change the minimum weight would be the SSGT min. However in reality you could not get there with all cars. If I were to pick a number for legal weight reduction I would probably target 750 pounds out as a stretch target.
This change in my opinion has removed the added complexity of GT and turned GT into if you can think it you can build it. I also think with the FWD conversion cars that Front clip / Suspension mods be opened up for all GT Cars or clearly defined most FWD cars have the aero advantage lets not enhance that unless it is the intent.

But hey what do I know I'm a Pontiac racer
Hmmmm Solstice with a RA 400....

Happy Holidays

Would this matter?
I'm looking at a 2015 rulebook OBTW. In General Regulations under 4:2 Ballast, at the bottom of the paragraph,"Maximum amount of removable and/or permanent ballast, unless otherwise stated under Class Requirements, is 500 pounds. Cars running 8.49 and quicker are limited to 250 pounds maximum, per SFI chassis specification.".

Structural Ballast?

Easy to add weight to any car legally,start by putting everything back in you ripped out trying to lighten it. When I had my Mustang fox body had to carry over 500 lbs. of ballast to run H/FIA. Did it and was never questioned about anything being illegal.

[Dyno]

With the newer model cars (2000 and up) weighing so much and the ability to remove so much emission and safety equipment out, it is common to being able to lighten the car 700 pounds or more without going to drastic measures. This should be taken into consideration.

This is still in the 2020 rules. the reason that I am bringing this up is because I ran into this about a million years ago when I was playing with the Sunbirds and dealing with the FWD weight breaks. The same would go for my latest project I would guess. In order to change classes I would have to add 840 lbs..
