First post to the forum, glad I found you!

I'm about to take delivery of a 2013 XKR-S in Italian racing red, very excited about the car! However, we have some rough roads here, tall speed bumps, etc., so I'm considering installing XKR springs, which I've read are 10mm taller 28 and 32% softer front and rear. In theory, this might also make the car slightly less tail-happy. Has anyone made the swap (either way) and can give me your impressions? If I swap to XKR springs will the ride be noticeable better? Will handling be adversely affected? I'm thinking traction might actually be improved on rough roads.

Any source for OEM XKR springs? Other options, such as adjustable coil-overs, that I should consider?

Thanks!

 

I will switch you my 2012 xkr springs for your springs? Car has 44k on it, obviously taken care of. Let me know

 

dcmackintosh,
Your handling would surely be impacted as I'm certain you will see more body roll/lean as well as some aerodynamic efficiency differences at high speeds.

On rough roads that have surface irregularity a softer spring will maintain more contact with the road surface. If this is for race tracks, most tracks are smooth, so a stiffer spring may be best.

It is a straight forward swap, so give it a try.
