Long time lurker, first time poster.

I've seen a few threads on lowering your X350, and wanted to post my setup.

Wheels:
Avant Garde M220
Front: 18x8 +30
Rear: 18x9 +30
(I also have 30mm spacers to make it flush to the fender, but I haven't rolled my fenders yet so I'm just going to leave it as is until next year)

Tires:
Front: 215 45 18
Rear: 225 45 18

Suspension:
BC racing coil overs. They had to be custom made, but I didn't spec custom springs or an extreme low kit.
(ride is surprisingly smooth and coilovers are fully adjustable so I could soften it more as needed. Rides a bit stiffer than stock given the 45 sidewall

Dash lights:
-Yellow warning light
-Messages: "Issue with Air suspension" and "CATS system fault" (or similar - I forget the exact wording)
-Not getting the Red vehicle too low message/light.

Taking it in a few weeks to get the codes cleared by a local Jaguar shop (hoping that's easy vs having to buy some sort of module faker)

 

Nice ride.
is this the XJR? Or xj8?
tell me more about your coilover kit?

 

It's a 2006 XJ8, and this is the kit I bought for it:

Took about 6 weeks to be made, but the quality is great and ride is awesome. Let me know if you have other q's!

 

I am surprised that you put tyres that "thin", meaning with an insufficient load index.
The standard load index of a 215/45 R18 is only 89, and it is 93 when XL.
Even a 225/45 R18 is 91 and 95 XL respectively.
For reference, the standard tyre on an X350 is 235/50 R18 with a standard load index of 97 (and 101 if XL)

 

So it’s fair to assume this fits he XJR also?

 

It should fit no problem, but I'd reach out to BC racing to confirm. They were pretty helpful when I was ordering so it'd definitely be worth the message to them before spending the money.

 

Interesting, looks good let us know if you manage to get the warning light off.
