hi, i have some 15 x 7 aero's, some have HDT cast into them and others have ROH cast into them. anyone know what cars where fitted with the ROH's? was it 'GM only' assembly line SS's etc?

Good question...Wheres Corsa when you need him Some original photos have not been recovered yet.

lol!! Some original photos have not been recovered yet.

The ROH's came out as a production replacement for a while, although ROH made the HDT's anyway!

With the design of the Aero rim the plan was to make them available to the aftermarket as well. The HDT cars would all get the ones with HDT cast into them and the ROH ones were for aftermarket use only and may also be done in other stud patterns. The HDT rims have two different stud patterns as the WB was different to the Commodore and the Aero's were available on the Magnum as well. Corsa

Yup, thats it, spoke to hdt and they said the original fitted rims were cast 'HDT' and replacement rims were cast 'ROH', all cast by ROH - GM/HDT copyright design another problem difference tho is that the orig HDT had dark grey paint and the ROH is black, I kinda like the black tho....
