Searching for front springs (rally)

[filh]

When I bought the car , it was fitted with selfmade coilover welded on stock strut . Easy to lift or lower the front , but pretty hard to keep the car on the road . My ae86 was acting like an fwd , despite all my settings .
When I fitted the stock strut , i use the same blue Tokico , with genuine springs , broken after two rallies . I had springs machined with a wire dia of 13mm( I think stock is 11,5mm or 12mm ).
On my last rally , I've been a bit optimist on gravels road and what happend?
strut , shock and spring were bent.
THat's why I want stiff springs .

first the optimist ride
