actually at $4,500 it's pretty reasonable since the package includes the following:
- front and rear skirts with color contrasting elements
- honeycomb-designed grille
- side sill kit
- integrated trunk lip spoiler
- oval-shaped exhaust tips
- 18-inch titanium colored alloy wheels, wrapped with 235/45R18 high-performance summer Pirelli tires
- performance lowering springs
- paint and installation (if bought as an option package)
A complete B5.5 Votex kit only includes the front, rear and side skirts and probably costs just as much if you factor in paint and installation.
This is OEM quality parts (polyurthane) and installation, and has a factory warranty to go with it -- I think it's a good deal.
