: Ever wonder what your suspension is REALLY doing under there? (Part 2)

Hello,

If you recall we posted some information a while back regarding the CTS-V chassis and the amount of rear cradle movement.

Ever wonder what your suspension is REALLY doing under there? We decided to get some useful footage to see just how much movement the rear differential cradle is getting under load. The results were pretty cool! We took multiple samples of video to see if it was just isolated to 1 certain car, or 1 certain suspension combination, model year, etc... The results were the same. We even loaded the camera up on our torque monster drag car and the results were still the same. Here is part 2 of the video clip "Chassis Movement".

So without further ado here is the video:

As you can see that deflection from the cradle mount has been greatly reduced. This now allows the energy to be driven into the corresponding suspension components. Now some of you might be wondering how or why this is relevant. Well it is said that a chassis that is allowed to flex under load is virtually impossible to properly tune the suspension. The reason this is the the case is because the variable rate of bushing deflection does not allow one to properly dial in the suspension. We have developed and designed a unique chassis brace that will increase the torsional rigidity without compromising the vehicles overall ride quality. These braces bolt into place without any permanent modifications to the chassis or any cutting. The results are a much tighter chassis that now acts as if it is performing as one. This forces the previously wasted energy, through bushing deflection and chassis flex, back through the suspension as designed by the GM engineers thus ultimately transferring the energy into the suspension.

By properly channeling the energy through the suspension rather than through the chassis or soft rubber bushings you can increase the following: handling, 60', launches, turn in, increased lateral grip, higher turn in speed, predictable handling, etc..

very nice product. What is the total weight?ANy lose of ground clearence? I hope to add this soon!

Isn't that of the front though? The ant-sway bar and mounts looked different.

the front subframe is aluminum(or it could be magnesium, I'm just positive it's not steel) the rear is most definitally steel though. the D3 video has a steel subframe, ergo.

Hello,
Thank you. Total weight is estimated to be around 20 lbs. No big loss of ground clearance. Most of the aftermarket exhaust systems hang lower than the bracing does.

Thank you,

Hello,
That is the rear of the vehicle. However the camera is looking back towards the rear subframe. The front subframe is aluminum and the rear is steel.
