Disco4 wheel load rating and RRS fitment

[Slunnie]

Hi all, would anybody know any of the following info regarding the Disco4 Style 104 20x8.5" wheel by any chance?

1. If it will fit over the 380mm Brembo 6pot brakes on the Range Rover Sport


2. What the load rating is?

Those wheels are 53 offset, RRS 8.5"rims are 47 offset. I'd be concerned that they would foul the upper control arm as per this link Wheel Offset | Range Rovers Forum (https://www.rangerovers.net/threads/wheel-offset.342914/) The wheels in that link are 9.5"inch though not 8.5"

Thats really interesting, I didn't realise there was that incompatibility also. Thanks for this Tote!

From watching this video (I've just found it), I'm gathering that the the 380mm Brembo brakes will fit behind the 20" Discovery rims when fitted to a Disco3/4

Even Disco 19" rims fit over those brakes which are the same as on my L322, currently wearing 255/60R19 on D4 rims.

The 20" RRS wheels fit over the 380mm brembos on my RRS with no problems, I have a set in the shed I can take a picture of the markings on the back of them if that's helpful.

Hey Graeme, are they are L322 6pot Brembos with D4 rims? That is actually exactly what I really was trying to find out! Thanks very much! The L322 Brembos are offset slightly differently to the rest.

Thanks Tote. Thats perfect as well, thanks very much for this! Greatly appreciated too. No need to take a pic

Yes, L322 6-pot Brembos allow fitment of any 19" D4 rim and therefore any D4 20" rim. L322 offset is normally +57. I initially had my old 2010 D4 19" rims fitted and now have MY15/16 7-spoke rims. A good 3mm clearance exists between the callipers and the rim.
The 6-pot Brembos were optional on UK D4s.

Thats really interesting, thanks so much for this! For the caliper clearance, is that to the face of the rim or the actual rim of the rim. Never the less the fit sounds like it is good. What makes this also interesting in terms of the fitment is that the L322 380mm rotor is offset abut 20mm further inboard (away from the rim face) that the other 380mm rotors used on the other vehicles like the RR L405, RRS L494 and Disco5 and they seem to bolt across to the Disco3/4 which also matches what you're saying about them being an optional fit in the UK.

Those brakes fill that wheel really well!!!

The close clearance is radial rather than between the spokes and the outer face of the calliper and is inwards somewhat rather than near the spokes as the calliper slopes more or less parallel to the reducing diameter of the rim as it approaches the spokes.

L494 19" rims are 7.5" which suits the 255/60 tyre better but I was concerned that their less offset might adversely affect tracking and self-centering on loose or muddy surfaces, so used 19x8 D4 rims. D4 rims are more readily available too and therefore cheaper as I wanted 6 rims, so 2 sets of 4, leaving 2 to replace damaged ones as D4 19" rims aren't the strongest of rims if abused.

Hmm, interesting. This thread has made me go & stick my fingers between the 6 spot callipers and the 20" rims on my L494 - so plenty of room for 19" there, but I'll stick to 20"
There is also clearance of (guess) 4mm between the callipers & the spokes.. Certainly looks tighter than that.
Now to wash my hands!

Have you got an L494! Best looking LR in my opinion. Thanks for this info, checking it out and getting grubby hands! Greatly appreciated!

[Graeme]

Maybe you could fit these rims as clearance over the callipers looks OK.

They're massive!
