Hi John
I made contact with Phil Singer, the editor of
www.vclassics.com, in the USA and somewhere along the line we discussed IPD's front ASB and this is what he had to say:
"I buy very little from IPD, but I do recommend their heavy front sway
bar (I think it's not beneficial to run a rear bar, and they will sell
just the front although they don't advertise it that way). It really
transforms the handling -- you'll like it." - Phil Singer
From what I can tell he quite reputable in the US on old Volvo's.
