20" Alloys on their way.
I have been digging at work(JLR) for info on why I had problems fitting 20" wheels recently. Below is a copy of an E-Mail Reply i received with a few names deleted of course.
20" for L319 are still under development. Proposal is to use the L322 Pirelli 255/50 R 20 tyre on a new L319 20" rim. (L322 rims don't fit.) *********** from accessories is doing the wheels. You'll have to ask him about availability. We're doing the tyres but they're not signed off yet. Since they're carry over L322 they should be available, although I can't reccommend fitting them until they are fully signed off.
Apologies if you all knew this was coming anyway.

Nice to have someone on the inside
I have a couple of issues with this. If tyres are a carry over from L322 (255/50R20), then they're 106 or 109 rated, which we've been led to believe isnt weight rated high enough for D3. 20" Supercharged L322 Rims will fit, as do RRS ones, but the bigger issue is how to stop the steering shimmy with 20's on the D3 as it doesnt have the damped steering rack that the L322 and RRS have.

no, serious head on...
L/R have 2 wheels in the pipeline
1 x diamond cut (which is meant to be the dogs cahunas)
1 x standard 20" which is a bit bland....
The new wheel, so i have been told is supplied WITHOUT tyre...this i hope is true as L/R wheel and tyre packages are priced out of this world.
Alledgely a developement bodykit car at Gaydon has the nice 20" wheels fitted but pictures are strictly embargoed till near releaase time.TLO has left the building.......

i asked the question on damped steering and got a straight what's that
So i assume no retro upgrade required for these wheelsTLO has left the building.......

Large One,
as a few of us have tried RRS 20's, and seem to have all suffered with the shimmy (apart from RonP, who's obviously got some better ointment), the key difference I could see, as we all seem to be trying RRS 20's, was the RRS (when fitted with 20's - as per TSB) used a dampend steering rack, which the D3 doesnt. It might be said that the 20's are 9.5" wide, so thats causing the shimmy, but I'm running RRS 19's, which are this same width with no shimmy, so I dont think its a rim width issue. The L322 20's are only 8" wide though.
the saga continues.

Pirelli 255/50 R 20 tyre !!!
That seems heck of a skinny for a 20"
Anyone fancy a shot at my 20" Super 7's with 295 grabbers??

Still digging for info

Question
Thanks for the reply Guys. Lots of D3 Owners already fit L322 wheels and L320 wheels to their vehicles with different levels of success. I personally fitted L320 Stormer alloys and got steering shimmy as it has become called. Other I Know have done the same without any problems what so ever. There are many theories including the L320 having an additional dampening on the steering rack which L319 hasn't. Can either of you shed any light on this please.
Answer
Hello
As you correctly point out, L320 has extra valves in the steering to reduce kick - back. It also has a completely different steering system. The L320 wheels and tyres are also a different size, which will affect steering, gearing, fuel economy, speedo reading, refinement, handling,etc.
I cannot therefore recommend you fit anything other than signed off wheels & tyres to L319. Unfortunately there isn't a 20" yet.
WIll keep on trying to nail this down .

nice one goffie - keep at it.
After looking at D3 and RRS, most front suspension/steering bits (apart from steering rack) looked the same, which is why I suspected this bit as being part of the issue. Yes, your guys are correct, in wheel/tyre spec for L320 is different, but if you fit L320 19's (inc RRS spec tyre) you dont get shimmy.

Well at the end of the day it shares its rack geometry with the D3 so it can't be THAT different and as under all circumstances LR either by option pack or TSB state the RRS must have a dampened rack to fit 20" then I suspect that it probably the conclusion they'll come to - unless the wheels and tyres they are coming up with are specifically designed to avoid the potential shimmy with a D3 undamped rack.
But at the moment it sounds like they aren't aware of LR's own rack recommendations on the RRS...Cheers
