I'm going to leave the lowering springs off. But I'm going to have the rear wheel arches rolled and modify the bump stops for clearance. Thundercat I strongly recommend you order the back issue of Jaguar World January 2010. This is a very good issue for the X308 enthusiast who wants to personalize there XJR. Check out the Silver/Platinum XJR with the 20in BBS Perseus wheels on Page 5. The rear wheels are 20x10.

 

that's my friend's car, can't help but say told you so.....front brake ducts need looking at too, or you'll have warped rotors from ineffective cooling, I guess you're getting to know how much work is involved with messing about with wheels and suspension......do Mina do returns? hehe!

 

Does his car have springs with the 20's? If no, did he have any problems with warped rotors with just the 20's on the car?

 

Thanks for the tip, January 2010 back issue arrived today, good stuff!

I have the US spec suspension on my XJR, and it does feel a bit un-planted in some situations, e.g. when braking from high speed (after overtaking)...
