Many thanks to Julian for this info. I took advantage of it, and am now posting my upgrade info. Luckily there are loads of Daewoo Matiz cars in the scrap yards in the UK. I bought a pair of springs recently for £25.00 inc delivery off e-bay. (Didn't even need to go and take them off, or get my hands dirty.)julian said:Standard Insight rear springs allow bottoming-out on roughish roads.
Daewoo Matiz rear springs are a direct drop-in replacement. Same free
length, slightly stiffer.
If changing to them, make sure you also swap over the rubbery plastic
sleeves that slip over the bottom few Honda spring coils. (Otherwise
there's lots of boooiiiinnnng noises!) Julian Edgar
At this price point, I'm in.Apparently "there are loads of Daewoo Matiz springs in UK scrap yards". Many US Insight owners want to install these springs in our cars. If a list of sufficient size of interested buyers were compiled, somewhere in the UK some enterprising soul may arise to fill the need or be able to direct buyers to a source or sources who will painlessly export these springs to the US.
I would be interested in buying two sets. Put my name on the list:
1. Hugh-Falls (two sets)
2. Kevin Dougherty
EV and PHEV conversions generally require additional batteries. Ride height changes with the load and to maintain ride height, a spring with a different rate is required. Peter has found that the Daewoo Matiz spring appears to be a satisfactory exchange for his loads. It may be OK for mine.OK, tell me why are we putting in new springs? I dont think it needs it for load carrying as I just drove 200 miles with a 200 pound wind turbine on top of the battery case (with some aluminum bars to spread the load!!) and experienced no bottoming.
I think one's need for stiffer rear springs must depend on the roads one typically drives and the load one typically carries. Having just driven 5,300 miles through Europe with 2 adults and our luggage (i.e., load capacity maxed out), I don't recall more than a handful of bottoming experiences.OK, tell me why are we putting in new springs?

The Airlift Co. Air Lift - Suspension Innovation Since 1949 support technicians suggested using their Suzuki #60793 air bags as a possible fit but had no specific recommendation. These could be a good solution for adjusting to variable load situations but if a known/constant load is being carried, like a set of batteries, replacement higher rate springs may be better........I wish there were air springs that could be installed inside the rear stock springs. One could increase the air pressure when a heavy load was carried to minimize bottoming without the need to install stiffer springs. One Insight owner claimed to have installed such air springs but never posted details.
