Disco 4 Suspension/shocks

Hi

Im looking for some advise for my Disco 4, ideally i would like to make the ride a little firmer, more that of the RRS. I love the Disco 4, but wish it could be a little firmer on the open road. I was maybe thinking harder shocks???
Not sure how it would effect air suspension etc etc.......

Any ideas/advice would be great fully received......

Thanks

the air suspension system can be programmed for ride height and stiffness. not sure how much it costs but they shouldn't have to replace any dampers. try alive tuning or twisted performance.

Thank you landroverlane, I wasn't sure if it could be done, ill look into it.......... I'm glad there seems to be light at the end of the tunnel.

Thanks again.
