I’m heavily researching this topic as well, although a bit different situation as I know its on original OEM springs and OEM replacement shocks (SACHS - unknown vintage). PO put on 305/70’s (33”) which are a bit wide and look a little stuffed.
I’m currently sitting at 20” inches center of hub to bottom lip of flare, so level but I suspect a bit saggy. I am 99% decided on going Dobinsons stock height replacement spring coils (C59-210/221V’s) over any other brand because they are planted but plush (or so I’ve read vs. OME which apparently need weight to feel good), and they are variable rate (vs. linear), so they can take a little weight for the few times I might load up the cruiser. I have no aftermarket components adding weight.
Also, according to
@crikeymike, the Dobinsons are a bit higher than US spec OEM springs, as they were spec’d by Toyota for the Aussie market that way (UAE come even higher!). So, in the definitive suspension guide thread, I believe someone mentioned in the reviews that their stock weight rig went up to 23.5” rear and 21.5” front using the hub/flare measurement. Hard to say this would be everyone’s experience because there are so many variables.
I’ll see how that looks/rides with these springs, new OEM Tokico shocks ($60/per vs. $$$ alternatives that are enticing but I don’t need currently). Then plan is to eventually (possibly?) squeeze 295/75’s (33.4”) under if I think they can work. Under 2” lift with 285/295s has been mentioned by many as an ideal look and setup if you are not looking to go big on max suspension travel.
Mine is an also garage queen and weekend driver. Your use-case may dictate something different but this is what I am thinking is the optimal set up for me/my rig configuration, and without getting into lift geometry.
Welcome any comments or before/after pics if you’ve done the same setup. Thanks!
