Just an FYI
I haven’t been successful in buying John Olson’s springs so I went to Mechatronik. Here is a cost breakdown of their kit… considerably cheaper than I’ve seen advertised in some places…
4 springs: €700
4 KW shocks: €1700
You can get one, the other, or both.
I’d buy the whole thing if someone would buy the 4 Koni classics I have here. Still in the box, got ‘em 2 weeks ago.
I’ll be buying the springs, at any rate.
