I have a quick question about my car.

I have a 1991 Trans Am WS6....i understand (after reading from another forum) that the 91 WS6's all came with 4 wheel disc brakes. well...my car has rear drum and front wheel disc brakes. does this sound right?

 

1991 was the year that a supplier shortage led to the installation of rear drum brakes for a period of time. The original where given credit for the Disc brake delete. Sounds like your car falls into group.

 

would it make this car fall into a category of being a more rarer breed?

 

One big NO......

 

well that sucks that they didnt put the Discs in the back...stupid supply shortage

 

I believe the foundry that made the castings was on strike at the time and they were the single source. Since GM did not want to lose any production they went with the drum brakes.

 

is is hard to convert to rear wheel disc?

 

Do a search on the subject a ton of info on it.
