Thanks for that, much appreciated. Also, I have another car not a Lexus!, but I am using the same 9.5mm spacers all round as the offsets on the wheels are too high and sit too far in the arches. When the spacers are put onto centre hub ring it makes the spacer flush to the ring, ie the wheel can no longer sit on the centre ring, therefore the wheel is held on by the bolts, these are extended as they are the bolt into the hub set up and not the studs out of the hub if you know what I mean. I know the centre ring is there to centre the wheel, but am I alright with just the 5 bolts holding the wheels to the hub now there is no centre ring to sit on?
