Now I know this won't be to everyones taste. But I'd like to fit a set of coilovers to my 2007 XKR. It currently has electronic dampers and I'm pretty sure that unplugging them will result in some sort of error message. I'm thinking of the BC racing coilovers. Have had them on 3 previous cars and rated them highly.

so is there a way of avoiding the error message? I was suggested that unplugging the module for the suspension would solve it?

 

These cars come stock with coil overs. What are you looking to improve in your cars handling?

 

I mean ride height adjustable ones. Looking to fine tune the height aesthetically. I also find the BCs give good ride quality

 

You can pull a fuse and eliminate the CATS error. I tested it when I was contemplating non-dampened shocks for mine. The exact fuse number will depend on year and model.

 

Excllent. Thanks, my car is a 2007 XKR. I'll check which fuse relates to CATS module.

 

Im installing my new air bag struts (full adjustable air ride suspension) this week and I just seen that CATS error today on the dash as well. I was told you have to pull the fuse but also unplug some module or something?

 

David why don't you go the xkr-s springs not only will it improve handling but will also reduce ride height by 10-15mm

 

It's something I'm very fussy about so like the ability to adjust the height to exactly what I'm looking for.

 

Then I would go short and shim up. I honestly don't see the point in a fully adjustable suspension when it'll be set up and left alone. It's not like we are running race cars that get different setups depending on the course.

I guess a more relevant question is, are coil overs with the correct dampening and spring rates available for our chassis? My experience with motorcycles gives me a dim view on the available products. Mostly sale brochures described how parts were sold for their looks but not actually applicable for the intended use / duty. Before I would buy anything aftermarket, it would have fully adjustable compression and rebound dampening as well as adjustable bump stops. Then there would be a mechanism to swap out springs to find the correct rate that works with the needed dampening. Kind of like the 'tune' thread. It's damn near impossible for an aftermarket to tailor products to such a small percentage of potential sales.

TLDR, I think buying coil overs only to adjust the height is going about it the wrong way.

 

The BCs have adjustable damping and adjustable preload with completely seperate height adjustment. You can spec springs if you ask. But the ones supplied have been great by past experience.

anyway. My issue is avoiding a CATS warning light.

 

You need to pull fuse 14 from the drivers foot well.

Very interested in what results you see with the BCs. I had considered them however was told by a few motorsports techs to avoid them due to the old adage you get what you pay for. Spires does offer a set of custom bilsteins from the F type for about 4x the price but of significantly better quality.

 

Handling was the weak point in my XK. If they could get the XK to drive like a Lotus it would be he best GT ever. Maybe your coil over's are what's needed?

 

For me coilovers have always been a huge improvement in ride quality compared to stock in the many cars ive owned. Especially when you start to learn how to adjust your dampers and figure out that perfect ride height. If I were to get coilovers I would have had bcracing-na.com make me a set, they do great work with quality coil overs.

 

What is a non-dampened shock?

 

If looking to improve handling go either the xkrs springs or eibach 20mm lowering springs

The springs on both are stiffer than xk and xkr the difference Is literally day and night

 

The springs on my XK I thought were already too stiff.

 

Perhaps they have been swapped out for the xkr variety as they are stiffer than xk and offer the same ride height ??

 

My car was 100% stock. Actually I thought my VDP was stiff sprung as well.

 

A steel rod? I'll show myself out..

 

Just had BC coilovers put on my 2010 Jaguar XKR & wanted to know how to turn the Adaptive Dynamics Fault light off.
