I hope this can help many people better understand on which springs to go with.
You decide which springs will work for you. I want to share the difference between FGY33 Springs Vs. Y33 Springs.
This is the photo that I took when I was changing out from Eibach to Espelir ESN149.
Eibach on the left. Espelir on the right. They both are made for Q45 FGY33. (Not made for Gloria Cedric)
Compare the design of the top flat coil to your factory springs. They look very close to factory springs.
In my experience I had to pull the TEIN out in 2days. The weight of the Q was compressing on top three coils sitting on top of each other making metal to metal pop/binding noise when I steer the wheels.
Tein Y33 Gloria Cedric application. To me it looks nothing close to the factory springs.
I also had steer to one side and lift the dust cover on the ground to check the shock travel clearance and the Q was pretty much sitting on the bump rubber. If TEIN works for your Q45 that's great.
This is a photo of espelir on the ground with enough clearance between the coils.( No noise at all)
I don't know why TEIN didn't work for me and few other people who had issues. I had no issues with Eibach or the Espelir.
This is how it looks with Espelir ESN149 on Volk SS 18" x 9 & 10.
Cheers!
