over the past 2 years especially during the pandemic lockdown, I've spent a lot of time working on my Autobiography XJL, in the pursuit of the perfect look/stance I have hounded various companies and suppliers trying to convince them of the potential of the XJL.

after much digging around and research, I have developed a set of OEM fitment lowering springs for the vehicle which not only enhances the performance at higher speeds, reducing the body roll when cornering but does not have an impact on the comfort of the car which needless to say has shocked everyone including the technicians at JLR dealerships.

Before anyone asks, the rear air suspension will self adapt and adjust to the correct height once the front is lowered, this has been proven and tested without any issues on various XJ's.

The springs are manufactured in the UK but I can dispatch them to the US and other areas of the world.

In the attachment pics, they show the before and after installing the lowering springs from the front to the rear stance, there is a significant difference.

Are you on the Modified Jags FB group? I think what would help the other members of the forum would be some further back side shots and pics of your springs. Stance isn't for everyone, but I love the look. I think I've seen your car on the page, and it looks great.

When you mention JLR approval, did you receive support in installation at dealerships? The OEM hardly offers aftermarket endorsement.

 

Do you have 4 different tires?

 

Hi

Yes, I am one of the admins on the Modified Jag FB page, my car is the cover pic, the springs were installed by my team as I am in the motor industry specializing in the visual modifications, hence all the carbon on my car is well as a bunch of other stuff like upgrading calipers, painting calipers, bodywork etc. When the car was taken into the lookers JLR dealership for servicing that's when it raised a significant amount of interest which was followed by a meeting between myself and the aftersales manager in the mass production of the springs that lead me to apply for patents etc.

How much does the rear end lower? It doesn't look like much.

 

between 10 to 15mm, the rear is on air suspension and the level won't be static and it's not supposed to drop significantly otherwise the ride comfort would be too harsh although customers can always get lowering links if they want but it's not recommended
