Thanks Lynn. I do have one wheel that has a little bit of wobble that you can see when it is on the balancer. They are Centerline Pro Stock wheels made in '86. The tires are not very old and still look good, but I don't think they are holding their shape at high speed. I have no proof of this, but I can't find anything else wrong with the car.
Guessing that by 86 Centerlines were all shank type lug nuts. That may be your problem. Manufacturer will tell you they are lug centric. No way.
I purchased two sets of hub centric rings for Centerline wheels to Chevy axle hub size. They are a must if you want to eliminate vibration. You will have to have them made though, as I searched hi and lo and found no off the shelf rings that fit. Cost is just under $80 for custom rings, but well worth it. Everyone I know who runs Centerlines without the rings has to re-torque the shank type lug nuts occasionally. I never do.
As for the wheel that wobbles, as stated above, if you can see it wobble, it is way too bent to use at high speed.
Be careful, man. Your statment "This thing gets wild at about 110 MPH" reminds me of a motorcycle experience I had in 1983.
Suzuki GS1100E. At the time, the fastest production bike around. Magazines said something about it being a "wriggling handful" at speed. I figured they were over stating the case. They were understating. One night on a smooth two lane black top with zero traffic, took her up to about 130 mph (didn't take long to get there, that bike would do 0-100 and back to zero in 10 seconds in the hands of a capable rider. Anyway, hit just the slightest little imperfection in the road and the handlebars start shaking violently back and forth, like 8 inches. Holy chit. Almost crapped my pants. Let off the gas. No change. Blipped the throttle. No change. Tapped the brakes. No change. Not until I slowed down below 100 did it even out. Parked it on the side of the road, sat ont he curb with my knees hitting each other I was so shook up. Sold it the next day. Feeling nastolgic, I did buy an identical bike in 2007 with only2500 miles on it, knowing that in my old age, I would never foolishly exceed 100. After two episodes of inattentive drivers causing me to lock up the brakes (no ABS), and my brother almost getting killed on his bike whild doing less than the speed limit I sold that one as well.
Anyway, get this ficured out.
