Suspension question

[Pappy]

I took the vette out the other week after registering it. The car run fantastic lots of power.One question though on acceleration when shifting I noticed that the rear swayed a bit when going into high speed? The tires on the car are 70's and are older,I ordered a new set of BF's but have not been able to get them installed since the weather turned ****ty here in NY again,I ordered
235 60's for the car will this help the sway? The sway bar bushings need to be replaced also,they are not that bad but I will replace them any suggestions?

Several things can cause the symptoms you describe - deteriorated camber strut and/or trailing arm front bushings, toe-in shims missing at the trailing arm bushings, excessive play in the rear wheel bearings, etc. If you're not familiar with the Corvette rear suspension, have a shop check it out; if everything isn't tight and properly aligned, it will have strange behavior under acceleration and cornering.
