Sport Shims

NOTE: The Viper is equipped with sport shims which can be TEMPORARILY removed if vehicle is going to be used in a sporting event such as an Autocross. The increased camber angle is not recommended for normal driving on street, because abnormal tire tread wear will occur.

There are 2 sport shims used on each side of vehicle's front suspension. There is one sport shim located at each of front upper control arm pivot bar to frame attaching studs. See Fig 1 . The sport shims can be TEMPORARILY removed which will change front camber angle negatively by one degree. This one degree negative change in camber angle will allow Viper to exhibit higher cornering power than when camber angle set to production camber specification. The vehicle can then be returned to production camber specifications without necessity of doing 2 complete front suspension wheel alignments.

When sport shims are removed, front wheel static toe must be reset to production specifications. This can be done using a trammel bar and does not require using an alignment rack. When sport shims are replaced, front wheel static toe must again be reset to production specifications. This can also be done using a trammel bar and does not require using an alignment rack. All other alignment settings will not be changed from production specifications.
