GT Classification Worksheet

Here's the combo:

LS1 Body style Camaro COUPE (1998-2002)
Automatic
327/275HP 1968 Camaro motor (OEM Heads) - 299HP factor (I believe)

Using your tips from the templates,

If I read correctly,

The heaviest coupe is 3370 in 1998. the factor is 12.08 and the HP is 285.

So 12.08 X 285 = 3443 (Shipping Weight) divided by my 299 HP is 11.514 which is my base for classes? So I can run the car at 3443 + or - 250. More specifically, my weight would be the minimum ratio for the class X 299HP + 170?

I would hopefully just like to confirm this and make sure that I am using the right shipping weights and base ratios (3370 lbs and 12.08)

Thanks in advance for the help!

Given the info from this thread, the original template I posted isn't accurate in regards to weight. Reread the entire thread. especially post 16 from Dwight.

Find your car on the Stock Classification Guide and take the shipping weight
from that car's heaviest gas engine with the trans you are going to run.

If your body is a 98 Camaro coupe auto, use the shipping weight of the one with the biggest gas engine offered. I don't have data here, but if they sold it with a six and a 427, use the weight of the 427.

Once you have your shipping weight, remember what they keep telling me. It never changes, just the factors with different engine combos.

Take your shipping weight to the engine listing at the top of the classification guide and divide the weight by various HP ratings to get class factors. Be sure to use the GT factors in regards to HP ratings. Find the posts here about HP weight factors for replacement heads, too.


EDIT: LS1 shows up in the Guide starting in 99. You need to pick a year to get the body weight right. It looks like that would be a Z28 coupe with the LS1 engine? I'm a Ford dude...

99 Camaro Z28 Coupe 427 auto weight 3291

327/275HP 1968 Camaro motor (OEM Heads) - 299HP factor (I believe) Yes

3291 / 299 = 11

GT/GA
