The maker of the OEM belt i am pretty sure is Gates. OEM belt through the dealer is close to $40.
I had the Contitech belt on my 924S for the 20k miles i used it and sold the car. I also have the Contitech belt on my 944 and have over 20k miles on it no problems. I changed 3 timing belts for people and they all used the Contitech belt, they havent had problems either.
The balance belt is only available as OEM as far as i know, i dont think ive ever seen an aftermarket one for sale.
Dont blame me if the Contitech does blow up though..
.
I would not hesitate to use a conti-tech belt again. Besides, that $20 you save off the OEM belt can be put towards a rebuilt head if the belt does break......
