Which discs go a GSI with Delco calipers?

[b943weg]

Hello All,
I have a GSI, E16 non-cat, with Delco calipers. Does anyone know for sure the disc diameter and thickness of the front discs that should be fitted to this car as standard??

Different shops are telling me different things...aaarrggghhhh!

Any help appreciated

should be 236x20 on standard brakes

Will 236x20 discs also fit the ATE calipers as well as the Delco ones?

As I've just fitted the Delco calipers (I had big brakes and big wheels, but want to fit the standard 3 spokes), then found out that they aren't the best, I dont want to buy some discs to suit the Delco calipers then have to replace the calipers with ATE ones and have to also buy new discs again!

astra mk3 d vans & cars had the 236x20 discs & ate calipers, and i think a fair few corsa b's did too
