Confirmed. (Sorry for replying to my own post. ) I got this from my service advisor. Take a deep breath, a retrofit ain't cheap...
Performance Plus Retrofit - $13,000
Several customers have inquired about a field retrofit for the Performance Plus option. We do plan to offer this beginning this Summer for $13,500.
This upgrade will include the following items from the factory installed Performance Plus option:
* 2 x Rear lower control arms with revised stiffer bushings
* 2 x Rear upper links with revised stiffer bushings
* 2 x 21" x 8.5" front wheels with 245/35R21 Michelin Pilot Sport 2 tires
* 2 x 21" x 9" rear wheels with 265/35R21 Michelin Pilot Sport 2 tires
This is a package engineered to provide the enthusiast driver with a more responsive car and added cornering grip while maintaining excellent ride quality. While this does not include the revised dampers and stabilizer bars that the factory option does include, we have engineered this package to offer the majority of the handling benefits without requiring a full suspension removal and replacement, which would be far more costly.
The added grip of the wider rear tires necessitates the added lateral stiffness provided by the revised bushings, so the rear wheels are not available individually.
Looks like the package includes 4 rims and tires as well.
