I'm not sure how everyone else does there's, but when I give weight and ratio's it is without driver, unless specified. Our weights are curb or wet rates.
AKA, full tank,
oil, and water.
I have to agree, 3,600 lbs seems awfull heavy. The DV II comes in at 3143 and we intentionally made it that heavy to meet the minimum that SCCA gave us. (3,100)
Mohuska, WC is still in business no? I think right across the river in Canada from Detroit.
If I, or anyone else told you to go buy something at this point, chances are you would be throwing your money away.
If you can "scale" the car. Have it weighed and get each corner weight, then "maybe" we could give you some ideas.
It does sound like you would benefit greatly with coil-overs on all 4 corners, just depends on which shock and what weight springs.
Just our rule of thumb on big blocks - 375 lb front springs with 175 /225 rear springs. Carerra, PRO, Alden, or Penske have all been great to work with. (I know there are others so don't start yelling at me
these are the guys that we work with the most.
Keep us posted, I would really like to know!
