Think the stock bushings on your Z are up to the task of a track day? Think again!
I was doing a once over on our C6Z after two intensive days of track testing a bunch of existing and new suspension products at Reno Fernley last week (watch for results and video soon)and found some bushing carnage.
We were testing the Z in a stock configuration and adding suspension components to determine some lap time deltas. With that we retained the stock control arm bushings for all the testing because of the difficulty of changing bushings at the track.
Both of the front upper control arms had severe slippage of the bushings. The interesting thing is that is must be from rotor torque. The upper control arms are both pulled forward on the chassis. I would have expected them to be pushed back (toward the rear of the car) from holding the car back under braking. Instead the torque on the upright assembly under braking rotates the upper control arm forward.
Here is a little video of the spindle under braking also. Look at the rotor glow! I'm in the market for some new rotors
Anyone know how to embed YouTube stuff here on this forum???
Looks like a perfect time to put in a set of our
Pfadt C6Z bushings. Also note our Pfadt camber kit installed in the pictures. We put some tape on the shims to keep them from falling out while we were swapping components.
I'll post a full write-up on our testing very soon. It has lots of interesting data.
later,
