Cause of squirrelly feel on hard acceleration?
I've noticed recently that my Z seems to be a little squirrelly on hard acceleration, almost "darty", which is rather disconcerting when the speed gets up there. It's almost like the car wants to go in random directions, and it takes effort to keep it pointed straight.
The only thing still original in the front end, is the steering rack, so I'm a little suspicious that maybe there's some slop in that... though I guess it's possible one of my other front end components has worn prematurely, with only about 10k miles since rebuilt. Any thoughts on what might cause that loosy-goosy feeling on hard acceleration? Thanks Andrew

Sounds like it's time for a 4-wheel alignment including thrust angle using the factory specifications as a starting point.

Re: Cause of squirrelly feel on hard acceleration?
Yeah, I was wondering about that... I had a Euro import shop do the alignment last year, it's never been quite right (little pull to the right), but I was ignoring it. Perhaps it's time to take it back for a re-do.
Unfortunately this is the shop that came most highly recommended in this area. Maybe it's worth a trip to Corvette Masters about an hour and a half from here. Not sure if they do alignments though.

Does it do it on completely flat ground? I found a marked improvement in this darting around when I replaced the lower a-arm bushings. It's still not zero but much better.

Re: Cause of squirrelly feel on hard acceleration?
Mine felt like that until I rebushinged the entire car with poly. Brand new inner/outter tie rods. And rebushing the steering rack. All my problems were gone instantly. I do all of my own work because I do a better job than any shop. The only thing I use a shop for is to mount and balance my tires and do a road force alignment. Thats it.
