The Ford Thunderbird 8.8 IRS...according to the "book" uses 750 lb springs, but I recon that with the lighter car, 650lbs will work fine.
Went in to King Springs through the week, and they swapped them again...
Drove it this morning....MUCH better...felt really steady and solid on the road.
The fronts have always been 350 lbs King Springs....I think they'll be fine.
Cheers,
Warren.
