Low-speed videos of launching the Z

[RebekahsZ]

Assorted videos of my Z at the track launching on bias ply slicks. Notice how the tire first moves forward in the wheel well, then the amount of squat and bouncing of the suspension. I think the bouncing may be a product of hitting the bumpstops... Will try to play with ride height to see if staying off the stops will reduce bounce. No video from last night when I turned launch rpm down from 4000 to 3000.

While I don't have anything technical to add, I just want to say cool vids! Its pretty interesting how that first 60 feet plays out in slow-mo.

Wow ! It's so cool to see how far the rear wheels move forward that much . My ZXT did the same thing during launch ( moved about 1.5" ) , the tires rubbed the inner fenders . Had to rolled them and made the rear subframe bushings solid . No more movement but has noise and vibration .

You might try longer, softer bumpstops.

Thanks, fellas. I want to figure out where to put my go pro to capture differential movement too, but I haven't been able to find a good mounting point (yet). JMortensen, I'm on that when I tear down this winter. I also am likely to spend big bucks this winter on shocks if dual adjustable konis are still around. I think something like minimal rebound in front and max compression may help along with max rebound in the back will help. Gonna try to video my droop straps to see if they are playing a role too. So hard to find someone to video the things Im working on while I'm driving. I'd love to have a codriver so I could watch the cars behavior more. Only so much you can do as driver and head lackey ll in one!
