2005 4.8is Suspension - What now?

[Mistermorgan]

Hey all

A few months ago I bought a 2005 4.8is purely as a passion project, it’s not my everyday motor (that has 2 wheels) I just saw something that needed some love and wanted to rescue it, like a puppy at the shelter right!

Anyway I’m a few months in and have fixed most of the textbook issues it had them all, valve stem seals, coolant transfer pipe and alternator bracket gasket leaks all fixed as well as a number of other bits of work with a tonne of help from you guys! The last piece of work I did was to replace the suspension control arms all around - mainly as it was making a horrible clunk under braking and could be rolled 3inches whilst parked since the caster bushes were shot and the tyre wear was so uneven all around.

Anyway after swapping all of these out and taking it to get some new shoes and wheel alignment today the tech tells me he can’t correctly align the rear wheels, they will always have camber and wear on the inside edge since the springs (previous owner removed air suspension and replaced it with cheap strut master spring set) aren’t a good fit for the car and it’s lowering the ride height too much, he has adjusted everything to the limit of adjustment and it’s it’s still out.

Now - since the rear tyres are $350 each I don’t want to just accept I and keep it like this so wondering what I should do next. Given a set of BC Coilovers is $1500 AUD I’m wondering if that will even solve my problem or if I am looking to spend that kind of money is there a better solution? Wildly, a part of me kinda wants to put the air system back in and looking at it the previous owner left everything in except the air shocks/bags.

What would you fine folks recommend?
