New boxter, last owner chopped springs- cause fishtail or tail wag at high speeds??

No way to know for sure until I get them out of there. But had a shop look and did not see any evidence of any other way other than springs chopped. Its too low and plan on installing factory springs back. I would have thought if they used lowering springs would be stiffer ride also? Had a car before lowered on springs, and the ride doesnt feel like it? I plan on checking wheel sizes tomorrow, betting some front and rears may be reversed?? Will be sure to update!
