Old springs back in - ripped up $70. Will let people make their own mind up but this is how it played out. Admitted last week they'd sagged lower than bottom spec - roughly 5mm according to them. Charged me $70 labour and fitted new SL rears FOC to supposedly compensate for tow bar. Car ended up 360mm drivers and 355mm passenger with tow bar - too high. Said car left at 350mm so I sent pic to confirm 360mm. Offered to fit original SSL's back in and we discussed aftermarket spring bases which I'd agreed to pay for. Offered to organise them - said they'd sort it. Got email following day to say decision made to refit original springs FOC but not doing bases? Called in to sort and asked why given springs had sagged can't we just supply new SSL's in the 'upper end' spec and be done with it. Said yes, but as other springs were 'within spec' I'd have to pay for them again. Um, say what? Said why supply new SL's FOC then but now have to pay for SSL? Said should have charged me for them also but tried to help. Said ok, just give me old springs back and I'm out of here. Said no, they'd be down a set of springs. Biggest tell though, admitted they don't do replacements until outside of range which is....+10mm, lol. Did the whole President of car club thing and dropped my Cousins name but still didn't mean poo. Needless to say, I won't be running King springs ever again.
