Anyone fit recaros or other bucket seats into their jag? Not a lot of aftermarket support for seats. Need a bit more side support for the twisties.

 

How would you compare the comfort and adjustability of the Racaro vs the stock seats?

 

What car do you have?
I have an XJR and those seats hold me in fine.

I have an xkr. Trying to figure out if it is possible.

 

If you don't need the rear seats you could always get a set of performance seats from the f-type (non tilt) they are always in abundant supply otherwise xkrs if you need tilt function for the rear seating.

 

I have a 2007 XK (LHD). The current seats are fine, but I'm always looking for enhancements.

 

Those certainly are track-focused seats, and look great. If you're tracking your car, they will be a big improvement over stock seats. But stock seats are fine for what you should be doing on the street.
Just an FYI regarding safety with racing seats and harnesses: You're using a 4-point harness setup, which will be fine for 98% of track driving situations. However, if the worst were to happen, i.e. a very hard frontal impact (track or street) without a submarine belt(s) (a 5 or 6 point system), you can potentially slide right out from under the lap belt - not a good thing. That's why, if you look at real racing cars, they have 5 or 6 point belts.
Be safe and enjoy the new seats.
Cheers.
