Tokico 5022 springs and KYB GR-2/Excel G struts - total mismatch or in the ballpark

[NewZed]

I have some Tokico 5022 springs I'd like to install but don't have a full set of Tokico struts to go with (HPs, 3012 and 3013, not Illuminas). In the meantime, I have KYB GR-2/Excel-G struts. Will the higher spring rates overpower the KYBs or will they work "OK" until I get the rest of the Tokicos? I've read that KYB recommends against using them with lowering springs, but not really sure why.

 

Any comments, from experience or theory, appreciated.

 

It's for street driving, lots of country roads, not much city.

Go for it. I ran kybs with my coilovers for years and they were great.

Thanks! One good story and no bad ones is enough for me. Next rain-break.

Just a follow-up for anyone interested - the numbers inthe FSMs don't seem to make sense for how the cars sit, by the year. The early 280Zs I've seen tend to sit lower than the later 77 and 78 Zs. But the spring rates for the early Zs are quite a bit higher for the same dimension spring. I think that means the early ones should sit higher than the late ones. Maybe I'm missing something or maybe the number are wrong. Seems odd. Not sure why WYSIWIG doesn't work, the format looks great in the editor.
