Unfortunately what this means for Corvette is the requirement to get by with those leaf springs while cars like Dodge Viper compete with coil over based suspension as it is factory configuration for these cars.
Over the years, GMPP has been selling a package called T1 to allow Corvette owners to increase the potential of their cars. The T1 package routinely consisted of new leaf springs, beefier hardware, anti sway bars and specific shocks, along with specific control arms and bushings.
In the past, the installation of this package was relatively simple to install and alignment was not difficult to achieve. Although GMPP offered optional T1 camber plates to remediate the problem of unlockable bolts, not surprisingly, these expensive parts did not work worth shit, especially when considerably more affordable aftermarket solutions were available.
With the latest generation of Corvette, things have changed apparently, no camber plates are available from GMPP for C7 generation and there is a small issue with the magnetic ride option across the board, available for all current versions of C7. The even more convoluted part is the fact that the alignment on the newest generation of Corvette went beyond difficult, as the rear caster has now become another alignment parameter and failing to account for it leads to outright dangerous high speed cornering manouvers. Of course, none of this would happen had GM finally implement the coil over suspension system but this is another full story all on its own.
What is the biggest problem with this newest generation of T1 suspension package? The ride height is the problem. As a result of the T1 package, the ride height will actually go up, due to stiffer springs and bigger anti roll bars. To add further insult to the track injury, the schocks that come with the package have longer bodies and piston travel which removes a potential for lowering the car which is actually quite important in racing activities.
The funny part is that GM somehow forgets about this part while attempting to charge over 3200 dollars for this UPGRAYEDD.
Of course, as with the frame braces, the OEM car warranty goes out of the window... Maybe GM and Juechter had autocross rallies as the new racing objective for the newest Corvettes? Certainly, after installing that warranty voiding UPGRAYEDD, there is no reason not to try this activity... Most likely this is what GM means by OFF ROAD ACTIVITIES, LOL...
Finally, the confusing part lies in the fact that Z51 package is advertised as handling package, supposedly to make Stingray more track worthy. Apparently now, GM approves use of non-Z51 Stingrays on the track? Oh yes, there is no warranty on the car anyway...
Chevrolet Performance announces the addition of the T1 Suspension package to the Chevrolet Performance Parts program. The T1 Suspension package improves the on-track handling capabilities of the Corvette Stingray.
EFFECTIVE DATE:
Parts will be available late 2015.
ADDITIONAL INFORMATION:
Developed by Chevrolet Performance engineers, this suspension package was designed to improve the on-track handling capabilities of the Corvette Stingray, including Z51 equipped models.

*The use of this engine or component in a new Chevrolet vehicle voids the powertrain warranty and may result in adversely affecting vehicle performance. In some cases, use of certain Chevrolet Performance components may result in the failure of other components or systems, thus voiding the warranty of the failed component or system.

The installation and operation of these components or replacement engines in new vehicles is intended for off-road operation only.
I don't get it, GM is offering an upgrade to make the car more track friendly? However their marketing strategy is counterproductive. If I buy an $80,000 car today in 5 years after the warranty has run out I can finally purchase the kit to help me compete in the SCCA touring 1 class. Or put it on right away and catapult my corvette into modern day technology and void the warranty. Obvious they are baiting unbeknownst corvette enthusiast to stretch their dollar further and buy into the bullshit that this will aid the new pig into becoming a Viper and Porsche track slayer. Only a complete moron would ever buy a kit that should have come on the car in the first place.
ReplyDeleteAblsolutely agreed. You can buy a C5 or C6 and be more effective for a fraction of the cost, not to mention the nightmare of repairs, with no warranty remaining. T1 is pretty confining class and rewards factory design, leaving Corvette with those leaf springs far behind others that use modern suspension that allows for actual suspension tunniing, independently at all four corners.
