17x9.5's front/rear - regarding performance

[Grimlad]

Are there any negatives to performance if I run 17x9.5" wheels on both front and rear for a '71 Chevelle?

Will they fit without modifications?

I plan on upgrading both front and rear suspension components (through SC&C) and don't want to work against the improved geometry/performance. I plan to slowly start using her for a daily driver and want the ease of rotation and spare storage (that's mainly why no staggered setup). I like that extra width for the slightly more aggressive look. Or should I go with 8's?

Any suggestions on tire setup and possible adjustments (offset and such)?

Thanks,
Sean
