areostar drum brake upgrade! with the 10" drums, upgradeing the drums to a heavier drum with heat-dissapateing cooling fins is as easy as lying to your parts counter guy. the areostar drums are nearly tiwice as heavy as the original unfinned stock drums and will take more heat before brake fade comes into play, they will also have greater resistance to cracking and warpage. do they work or fit any different, no. but when your in a situation such as towing a heavy trailer, they will be worthwhile. this set was speced for a '93 areostar 2wd 4.0 cost was about 50 per drum @ autozone.
