I got 07 FD2 Sport
I bought a set of S-tech and box says FD2 - but when I went to get it installed the installer says it fron springs do not fit the car. I googled the TEIN code on the box and it says it is for CTR FD2R from TEIN website japan.

Now, does that mean I return it to the shop and get the FD1 TEIN S-tech? reading the trail people have posted up that AUSD model FD1 and FD2 (sport) share the same suspension?

Can someone please confirm - and if so, what about spring rate? because FD2 engine is heavier>
