Bill,
I have an older super stock camaro. I have a coil over/ladder bar setup in my car. I also leave on a trans brake. With a good 350 running SS/HA I ran 9.92 with 1.28 60 ft times. I now have a 327 in the car. it does not leave quite as hard. The car is very consistent. I do run a radial tire. I use the M/T 12.2x31.25 radial tire. I have had good luck with this tire. Hooks good and is much faster than the Hoosier bias ply tire that I ran prior to the radial. I back to backed the two tires and the radial was .013 quicker on several tests. I would recomend the radial tire. You will have to experiment with tire pressure to find the sweet spot for your car. Start at about 12 lbs. and work up from there. I have a single adjustable shock in the rear and double adjustables up front. I am happy with this setup. If you have leaf springs under your car now and change to coil overs make sure you install some good quality heim joints in the front of your ladder bars. The front heim is the only connection point to the frame. If this heim fails the rear end will move forward or backward and cause heavy body damage. Also you should instal a retention device at the front of the ladder bar around the heim to keep the rear end in place in the event of a failure. Most of the older cars do not have this. I had to retro fit my car after I converted from leaf springs to coil overs. Good luck with your project

AFCO offers two unique valving specs that are an option. BNC & BNR. Stands for Bull-nose Compression & Bull-nose Rebound. You would use BNC on the front and BNR on the rear. What that means is the initial hit on either compression or rebound is very solid and less so a as the shock goes through it's travel.
I just had my 4 AFCO's revalved to this but have yet to run them so I can't say if it's worth doing. I also had the rear valving stiffened up considerably from what was offered initially. But keep in mind I'm a stick racer. Opposite of what Rod stated earlier, I will be running a light spring on my rear coil-overs. That allows you to pre-load the spring to get the ride height and when you launch that stored energy is put to use. Rod having the shocks in front of the rear may have something to do with this as there is less leverage working the shock / spring.

My car is pretty much like Mike's was before, older Super Stock car with Ladder Bars, Mono Leaf Floater, and Comp Engineering shocks. I leave at 5800 and the car reacts fine, my best 60 ft is in the 1.37/38 range and on a good pass the car will really get sky high. I would save the money and put it somewhere else if the car is working fine with the ladder bar.

Smitty,
Thanks for your thoughts. The mono-leafs are an interesting idea. Beyond that, any changes would be major, and beyond the realm of establishing a baseline. Bill Rolik SS 1514 |
