some tires wheel hop more than others. if it's a stock car and you can spin second you need a stickier tire. with a good compound you should be able to get on it in first and not spin unless you drop the clutch

But your car is almost 10 years old. The shocks bear the weight of your car, driven, or not. BTW, it's not really wheel hop, it's drive line shake in C5s. Best cures for it seem to be warm weather, stickier tires, and perhaps a differential brace. In straight axle cars, wheel hop is caused by axle wind-up, or the torque twisting the axle housing clockwise, perpendicular to the drive shaft. In both cases, damage soon follows.

if i detect any wheel hop i always back off
there are some good articles about axle wind up in the c5

My point was; it's usually not one single thing causing hop, but a combination of factors. At the same time, a change of just one factor may,(or not) fix your particular situation.

Tire recommendations? What are you running that sticks in first gear?

you can even roll on the throttle in 1st in 50deg weather and get them to stick on premium asphalt . in warm weather it's easy
tires are also way above average in the rain. i was able to carry some pretty serious speed in a downpour through an area i'm use to driving.
the real highlight of the pss is michelin using a street oriented compound that doesn't have to be over 100deg to hook, which, many of the extreme category tires do. i've driven the ad08 and XS on other cars and the XS has to be above 90-100, the yoke is better in cooler weather but not as good as the new pss. it's really the ideal street tire

I'm sure the '04 shocks are good and I wish my previous owner wouldn't have swapped out his for Bilstein's but I'm anxious to try out my Doug Rippie custom valve Bilstein's over any '04 shock.

I still haven't installed them yet, though, so I might as well have

I got a real good sale price on Koni FSDs a few years ago, and they were better than stock '02s, but I don't road race, so I can't say how they compare in that venue. If I ever need to replace them, I think I'll just get coil overs.

We've had this discussion in at least, what, ten or so threads now? Like forum Groundhog Day

i mean, it's not a bad idea and as wide as the pss is it may not look bad. i know the 285 35 would look fine

In one of the threads we both posted in, I placed a photo of a 255/35-18 Federal on an 18x10.5. It was stretched due to the 1/2-inch wider wheel, but it wasn't insane like you see from the VW crowd, and a PSS would be less noticeable, as you said. A 265 would probably look completely normal, since that's nearly the same width as the mounting surface of the wheel, and I bet that the traction control system wouldn't even notice that the front and rear diameters are slightly less different than stock (mine are and I have no issues with TC/AH).

Then my Z must be stronger than most, though temps could have something to do with it (doubt it) but even with NT05's on mine I can hit the gas hard in 1st and it always breaks loose no problem. 2nd can be questionable. Last drove it when it was in the 50-60's so I think the tires are ok in that temp range. Only engine mod is a Blackwing. '04Z...and wheel hop is never an issue with it.

when it's warm it will easily rival it though.
how are you hitting the gas anyway? rolling your foot or punching it?
cold weather is a double whammy for traction. 1st tires have less of it, 2nd your car is making more hp
pavement is also a big big deal. on brand new fresh asphalt you'll have a lot more traction than some old back road with a lot of rock tops for a contact surface
it's pretty easy to break 1st gear in cold weather unless you're on perfect pavement and roll the throttle

His source would have been Tirerack. Also, at GM Part House has inferred that the 2004 GM shocks aren't worth the money.
Also, the 2004 GM Sachs shocks are made in Mexico as opposed to Germany. Pick the quality that you want.
