Sounds like you've had rear springs from a Lusso fitted. A lot of TIs have been registered as Lusso, so when you use your reg to look for parts, you don't always get the right part.
I have a '10 2.0L TI Sportwagon, and had my rear springs replaced about a year ago. It was done under warranty, but I had to tell the guy what springs to use, as the parts search was showing up Lusso springs.
There should be 4 painted dots on the spring to identify what type it is for. Yours looks like a Saloon, so your rear springs should have White/Blue/Yellow/Yellow if it's a TI trim
A Sportwagon TI has Yellow/Yellow/Orange/White.
Q4 models have different springs altogether. It's quite confusing, which is why a lot of people fit Eibach springs instead.
Hope this helps
