First of all, what brand are these springs?
I doubt they're Teins. Looking at that rear end, I'm thinking they're custom fabricated springs but only the seller can verify the reason for this stance.
If these get refunded, I suggest you go for Coilovers since lowering springs will blow your stock struts in a matter of weeks or months, you'll end up replacing struts and at the end of the day, the amount of money you'l be spending would be more than the price of coilovers you can get right now
