Hi all
New to the forum and this is one nice site for F10.
I hope someone can help me out with this ,

I am looking for lowering spring for 523 but H&R only offers springs for 528 and higher , according to their website.
So do you think this HR spring for 528 will be good on my 523 ?
IF not I MIGHT have to wait for KW in the mod shop in my area.

And when installing the spring , do they have to take out my back seat ? Saw some posts mentioned about it , or was it only needed if the car comes with some special option?

Thanks
