Wheelhop question Riding in my friends 2004 Z06 (14,000 miles), he has no wheelhop. Getting into my 2002 Z06 (36,000 miles) immediately, in same conditions (drizzle/light rain), I have plenty. I don't care too much to race around in the wet but any difference like this is a sign something is slightly off...
My main question is: are there any differences notable between the 2002 and 2004 Z06 rear suspensions? Different shocks, or suspension settings perhaps? I've heard people say "swap to z06 shocks" to fix the problem as well as "swap to coilovers" with the latter being extremely expensive, so if its something like an updated damper in the 2004's it'd be a relatively cheaper fix. If there's not any differences, its definitely not a blown shock or anything of that nature, the car handles perfectly otherwise.
Other than the usual recommendations (coilovers), what else can be done to reduce or eliminate wheelhop in the C5 Z06? I've seen control arm bushing sets from $100-300 to replace all bushings on the control arms - is there an upgraded bushing set available for the transmission/differential?
Edit: his car is lowered slightly on stock equipment, is it possible the bit of extra preload placed on the leaf spring would effectively limit wheel oscillation?

I'd say when I just went out to see what variables came into play, 1/4 of the time it simply spun and slid out, with no rear chatter at all, but that was under very slow throttle inputs which probably doesn't put wheelspeed more than 10mph over vehicle speed. When he demonstrated for me, it went out very quickly and wasn't that slow at all on throttle input.
We're both on the same OEM tires, 295/35/18 Eagle F1 Supercars, he probably has more tread than I do.
I need to get my wheels balanced but its hard for me to believe that its a wheel-balance issue... as that is typically only a few grams of difference.
No differences that you know of between Z06 suspensions through the years, though? I'm getting an alignment soon, so I'll just tell them to shoot for 2004 alignment settings, regardless of any known difference I suppose.

Can't speak for the 02 Z06 but I installed Z06 shocks on my C6 and my wheel hop disappeared. Maybe your shocks are slightly worn. How many miles do they have on them? Regardless of what tires you have you should not get wheel hop.
If stiffer shocks doesn't fix it then harder (or polyurethane) control arm bushings should. You have to dampen vertically and horizontally to eliminate all wheel hop.

04 Z06 shock were pretty dramatically changed..different dampening and valving and just a lot better! do a search this is talked about a lot on the net

i use koni fsd shocks no hop..plus! better handling
cost 200 bucks more than the 04 Gm Z06 shocks

Mine is not a ZO6 but it has had wheelhop bad enough to break 2 rear ends. I think the tighter the shocks are the less wheelhop. Mine has the adjustable suspension pkg. and it broke both with it in the soft mode. It does not wheel hop in the sport mode.
