Let's talk fuel cell for a moment. How high does it sit in the chassis,how far to the left is it? Always carry a fuel load of fuel during a dry slick track at the start.
Try using a 3" on the left rear,bring that tire in somewhat.
Take sometime and check that the lower control arms in the rear end going to the bottom of the frame are in good and solid shape,there years of GM products do suffer from frame rot in that area,and the flex or movement in this area and change the cars handling.
A nice stiff right front shock maybe the answer.
Just because the rules say you can not add weight,many racers are masters of placing weight as needed in areas that seem normal. Next time you go to the track,look at the size of the fuel cells. Many racers have been known to build their own cans for the cell,loaded with weight on the left side with the cell moved to the right.

Always try to run the stiffer spring on the left rear,3100 seems light for a 75' cutlass,did you get an accurate weight? 40 percent rear is terrible,the worst car i ever had had 48.

You've GOT to get the rear percantage up! Think weight! Big old honkin bumper! Make one out of a piece of cold roll steel! Big fuel cell! Trunk lid with all the inner supports and latches. Full floor in the trunk...maybe out of a piece of half inch plate? How about that flimsy battery box you've got there?...wouldn't a nice 1/4" steel plate job be better? It would probably hold that monsterous truck battery you're about to put in. Think weight! Don't break the rules...but think about what they do not say!
BTW..close up the rear stagger.

that cell will help out alot and also can and do you have the rear horns tied together thats one good place to hide weight and keep in mine the further past the axle you put weight the less you have to use. i know alort of guys that use a 2x2 square tubing filled with lead to tie the tear frame horns together that can't add weight another way i've seen guys like you run a 8 or 16 gallon cell in a 22 gallon can and fill the bottom with lead or other metal plates to hide it

if your after rear weight percentage, instead of just adding weight in the back, try lightening the front (will do the same thing but keep total weight down, which means speed)
lighter front bumper, maybe made from exhaust tube - cheap, crushable, light, and surprisingly strong.
remove all under hood bracing.
remove all factory brackets that aren't being used.
try making engine mounts that move the engine back 1" and to the left 1" but keep them looking stock. the tech inspectors probably won't notice and you'll be amazed at how much difference it will make (don't forget to check tail shaft length after).
move your seat and pedals back as much as possible.
creative thinking is all thats needed.

Unhook your rear shocks next time you scale the car.
A nice big x under your fuel cell, for saftey reasons of course, would help, especially if it was made of some real heavy material. Tell the tech guy your just concerned for your saftey and thats why you "over" built it!!

Well, after the changes already made. I added a spring cup. The car was very fast on the outside. We ran very well all night. Now I have to contend with getting a little more bite off the corners on a dry slick track. The handling is ok. I am running a 2" backspace wheel on the LR and a 3" back space on the RR. Should I go wider on a dry slick track, or go narrower? I'm not really sure. Also, ordered new cooper cobras today for the rear. That should help.
Thanks
Rick
