My 56 has traction bars with 225/70/75 TAs, 55 is mini tubbed with 295/50/15s and traction bars. You are correct about the unilugs and PIA.

Nothing wrong with Cragars just get the non unilug versions.

The only time I have had a issue with traction bars and clearance was my 55 and it was due to being minitubbed, the pockets limited things.

One of the best hooking street cars i have ever had is my 56, it has South Side Machine bars and 225/70/15s on 15x6 Torque Thrust Ds. Everything I own except front wheel drive junk has a posi, 56 has a 3.42 58 Olds 9.3 posi.

As far as speedos go real men don't need them. My 67 Camaro SS 350 has not had one since the 1970s and when I built the 55 I never bothered hooking one up. As long as you have owned that car you know the feel of it, plus you have a tach.

255/60-15 tires work great on many GM midsize and C3 cars for generations and I have used them on many of my cars over the years. Especially if you can run the same size on the front, which I always do. On my 55 I am running 275/40-17's front and rear.

255/60 /15 worked well on all four corners of my 78 Corvette, 235/6015 is about it for my 74 Z28, it came out new with F-60-15. My guess a 55-57 is closer to the Camaro on tire size.

I am leaning toward the 235/70R15 tire for the rear and 215/70R15 for the front. Fuzz, thanks for letting me know that information. Those are exactly the size rims I was thinking. I agree on the cost but I think everything Is expensive now.

15x6 and 215/70/15 work very well on front of my 55.

I got my 56 at 14 and 72 truck at 17 so I can relate.
