Banpei's two door panda Trueno from Japan

[banpei]

Inquiry to Apex didn't help either: they sold the last set for the AE86 in 2015 and have no documentation on them. That set sold in 2015 was probably my set, as I bought it in early 2015.
I tried finding more information online, but nobody knows the spring rates of Apex. Even new sets don't get advertised with the spring rate. Which means I have low expectations for these springs when fitted on my car. But they were fine for daily use on my AE86 back in 2005, so they should be fine now as well.
