Bumping this as I'm thinking about lowering my XKR-S. Spires no longer has springs listed on their site, Adamesh has springs only for 4.2L models, and Mina looks to be a rebranded set of the only springs available (H&R).

Are those truly the only springs available for the 5.0L models or am I missing something?

 

Keep in mind the R-S’s already 10mm lower than and XKR, H&R may make the car too low. Without going to custom coilovers, KW adjustable springs are the only one I can think of at the moment.

 

It doesn't look like KW sells the HAS kit anymore. H&R seems to be the only option that I might have to go with. Edit: I just confirmed that Spires still makes the 5.0L springs so will be going that route. My one question though - since I have an XKR-S which has a firmer spring rate, and I move to an XKR lowering spring, won't my ride technically be softer?

 

If you are going to do it... do it right.
