Did search... still a little confused...
I was looking to get Stillen pads, but they only make 82 to 88 pads ?

http://www.stillen.com/product/brake...age-28027.html

Then when I go look for calipers for a 91, I see "with or without" Performance package...

I have a drum rear. I know there was a shortage of disc rears that year. The front disc can't be too large, I have a set of 15" turbo cast wheels on them...

Is there an RPO code to look for?
What is the difference between stock and Performance Package?

Thanks,

Rafael

 

Stock is 10.5 rotors with single-piston Delco-Moraine iron calipers. Performance is the so-called 1LE package with 11.7 rotors and dual-piston alum calipers—doubtful that your car is so equipped.

No such code in the RPO...
So the non performance package brakes for a 91...

How about the 82 to 88 Stillen pads, I assume they are for the stock 10.5 inch rotor and DM calipers?

Thanks JamesC for always kindly sharing knwoledge,

Rafael

 

The above fronts will fit all non-1LE cars, 82-92. The rears will only fit 82-88 cars.

Cool, I'll send Stillen a note cuz they don't even come up when it's a 91 Firebird... just the Hawks pads...

 

Keep in mind that Stillen is a Nissan/Infiniti parts place, so their catalog may not be 100% correct for other makes...

 

You want the Stillen D-154HD brakes for the front. (10.5")
