stick your head under there and look
i would suggest that also. with most commodores you can see the springs by looking under the rear behind the wheels.
However, since you asked, i shall provide...
These ARE NOT commodore springs (Cant get on ebay at work lol) but commodore ones are just different size. The middle two are rear springs for a Live Axle, and (this is a bit of guesswork, i haven't had anythingto do with LARS) the bumpstop sits in the top and bottom of the spring. If coils were cut off, the spring changes in height, but the width is not affected, as it is a constant width the entire spring. Not that I condone it, but it can be done.
These are IRS coils. Note that the coil is fatter in the middle than at the top and bottom ends. Also note the coil ends are tight to fit just over the bumpstops (i believe its bumpstops anyway). This is what prevents them from falling out. You can see now if they were cut off, the bigger space for the bumpstop would allow the spring to move around and leap out as soon as you hit a bump.
Just thinking about it, urs is an Acclaim correct? AFAIK VS acclaims had IRS as an option, so it may or may not have IRS. I would think though, if it did with cut IRS coils, they would've bounced out by now...
Have a look at yours as soon as you get the chance, just lie on the ground and have a look under. Your springs are more than likely black from factory. see what shape it is and go from there. also check the spring for signs of being cut. whether it's IRS or LARS and it
is cut, i strongly suggest replacing them wiht standard or replacement lowered springs ASAP
Cheers
