"G" Body suspention tips ?
 

Hey there, I have a 1984 cutlass that I am slowly turning into a stock eliminator but right now its just a 13 second bracket car with a 355.

I just recently swapped out my 7.5" ten bolt 3.73 posi, for a 12 bolt 4.88 posi and i am running 30x9 goodyear radials with the steeper gear. to make these tires fit I had to run cargo coils in the rear does anyone know if these work well for weight transfer in these cars ?

I'm also using the stock upper control arms (The pinion angle is way off and i am getting major shutter off the starting line)

I ran my car at the National open last weekend for the first time with the 12 bolt and like i said i was getting big time shutter off the launch, and also my 60's were all over the place from a 1.956 to a 1.880 and it felt like it was hooking up every pass
Will a set of adjustable upper control arms fix the in consistancy off the line ? and is there any other tips to get "G" bodies leaving the starting line better ?

Thanks,
Craig - C693

You need to start fresh with coil springs both front and rear ( Moroso will work ). Shocks need to be race specific and in this case a call to Calvert should give you what you need . Any of the major control arm companies will also get you in the ballpark along with a one degree pinion angle ( to start ). Also, as Alf Wiebe will tell you , use a rear sway bar !

sounds like binding of upper control arms. stock uppers and old 12 bolts cause binding due to angularity differences. need the uppers changed to rid yourself of this problem to start.

I guess the question is, is the 12 bolt modified to fit the G-body? Are the upper ears located in the proper angle to the upper control arms? If it was an "A" body 12 bolt, the upper control arm attachments are not in the proper location. You probably can force the control arms to fit but it will seriously bind. Post a little more info on the 12 bolt install.

They make the control arms to put the "A" body rear in the "G" body, with the correct angles.
Can't remember who, maybe the "Iceman", I think there's a product line under that name, think he even sold/sells on Ebay.

There was also a 12 Bolt made for the G-body. Oldsmobile had it done and was given out to the factory cars. Just like the non computer q-jet & Dist. There were parts from Canada.
