Greetings from Estonian senator club!
I have a question about the differences in Commodores and Opel Senator B suspension. Does anyone have some drawings to the commodores (VP...VS) front and rear IRS suspension? Because I did`nt find nothing on the web. I can then compare them with Senators drawings and see what differences do they have. I am maybe interested of buying Whitelines swaybars or urethan bushes from some other australian maker. Because they don`t make nothing in Europe for Senators.
Many thanks! Kaido
Pretty certain that most Commodore gear won't fit the Opel. While they do look very similar the Opel chassis is a couple of inches narrower. While there are other minor cosmetic differences, I would say the narrower chassis will cause you issues.

maybe find a good engineer and get some made up from old parts?
Well, that was my last idea to modify the parts by my self or to let make them by someone if I don`t find nothing on the market. But I think it`s not a big problem if the senator is a little bit narrower if the swaybars are similar and the installation points are more or less the same then it can be fit there. I have a senators front suspension drawing here http://web.zone.ee/ea02/front.JPG and rear one here http://web.zone.ee/ea02/rear.JPG if someone can give me similar drawings to commodores suspension I`ll be very thankful!
I think that you will be better looking for another solution as the supension designs (from the pictures) between your Senator B and VN-VS are quite different. The VN-VS are built on a stretched version of the floorpan of the previous VB-VL - = Senator A + mods - with a new design on the front with the VR-VS. The IRS control arms look similar to the VP(VQ)-VS but the Holden's didn't get the toe control link until VX (which have a different design of semi-trailing arm).
e.g.: On the front the ARB link ends are turned 90 degrees - not an insumountable problem but that would suggest that they aren't going to be a straight swap.
I have a VN-VP front ARB floating around which I can measure for you if you wish - one for a live axle rear only though. I think that they are the same dimensions as the VR-VS anyway.
Thank you Cheap6, that was helpful I think I can use some other Opel models swaybars and modify them to get more stiffer bars.
