Firm/Track Alignment for 2016 XJR ?
#1
![Question](https://www.jaguarforums.com/forum/images/icons/icon5.gif)
Hi:
I have a 2016 XJR supercharged. i always find the ride was too soft, so i brought to dealership. They said i have an alignment problem and require an alignment work. When i ask can they make the alignment value which give me more tight/stiffer ride, they said they cannot only if i provide them with my own alignment value. I did some google search without any result for that value. Can someone give me suggestions on alignment value. I am a track car driver, so track alignment or much more tight alignment is ok for me.
Thank you !

What tire pressures are you running, The Door sticker on that XJR, I think. says 41#. I run the same size tires and find that 38-39# give me the best ride and firmness. Of course, the tires you are using can make a difference. I swear by Michelin PS4Ss, and I have tracked my XJ and an XJR and they are geat fun on the track.

This implies that if you're seriously tracking a car, you should be starting with lower, not higher, pressures, given the greater rise in temperature, and thus pressure.
Don't forget that the tire pressure is not chosen for reasons of ride quality. You're trying to get even pressure across the tire, thus maximizing grip and minimizing tread wear.
On a road car I start with the pressures on the B pillar plate, and adjust based on the tire wear.
