I've got a similar setup in the summer on 20's and no issues at all with ride quality. now I'm wondering if the V8 sport shocks would be a direct swap and forego the cost of the Bilsteins...I read the Bilstein HD are very good though I've not personally tried it.
I haven't decided if I should stick to Stock shocks or go for Bilstein HD for the xc90.
Currently even with the Stock shocks with upgraded Endlinks, front and rear upgraded Anti-roll bars, front strut and bottom H-body brace handling has improved significantly .... and still very comfortable too on my 20" wheels. So I guess a balance must be striked somewhere in between comfort and handling.
Care to elaborate? What did you notice that was different, pros/cons?Bilsteins are great. Don't even consider OEM. Seriously.
