For the 1997 model year, the Camaro got a new interior and new tri-colored taillight that would be standard on all models from 1997 to 2002. It was offered with a "30th Anniversary Package" which included unique orange stripes on white base paint. It was available only on the Z28 and SS models. 3352 30th Anniversary Z/28s were made in 1997 and 957 30th Anniversary SS cars were built. An additional 100 30th Anniversary Camaro SS vehicles were modified by SLP to include a 330 hp (246 kW) version of the
LT4 engine (108 total LT4 cars were made, 100 US, 6 Canadian & 2 prototypes). While the LT4 made it the fastest factory Camaro available, it was also by far the most expensive with a price of over
US$38,000. New wheels became standard POS this year (except on the base
coupes), being a 5-spoke design, (17" ZR1 style on SS coupe models) available in either polished or chrome (or white on the Anniversary Z28 models), replacing the previous 10-spoke "salad-shooter" design.
In the Z28 models 0-60 was 5.5 seconds and 1/4 at 14.0 seconds. The new SS models 0-60 times of 4.8 seconds and 1/4 at 13.10. Rare SS models with the LT4 engine got even better with 0-60 times in 4.4 seconds and quarter miles of 12.90.
I think shane is right, I think the Z28 badge was added.
The "SS" was on the side of the car (white car with orange stripe paint), The Z28 was on the back.
