Wow! that looks amazing.
just wondering how hard was it to grind down the calipers? I am desperate to do the same for my P400 X. Wish there was something that was more plug and play.

You can swap calipers out if you have the regular P400 rotors and not the even larger ones that come on some of the models with 22" alloys.

Grinding is not difficult just takes a while if you're new to it. I am slow and a veritable novice when it comes to this stuff and it was a bit of a grind. Some rims will need less mod than others.



Couple of good threads on the forum and a nice write up by Saltek Motorsports here.

Gavin: can you confirm those calipers Part # (LR102243 & LR102246) are correct for a '23 MY X-Dynamic SE w/ 20's? Would love to swap calipers so I can run both 20's and 18's... as long as no loss in brake performance (or durability). Thank you!!!

I've not used them but from the many months of digging I've been doing here and elsewhere I'm 99.9% certain these are the correct part numbers. A member @mshotel posted in another thread some months back that they had fitted them and were running 18's on their P400. Thesecalipers are listed as fitting the 2020 P400 on OEMparts website https://landrover.oempartsonline.com/

They look identical to a caliper swap another person did on FB. I'll post the picture of them later.

Essentially AFAIK its a Discovery 5 caliper. If you have the regular P400 brakes, this is the caliper swap. ~$200 a pop on the listed site. If you enter a MY22 or MY23 VIN they will come back as not fitting. Enter your model as a MY2020 P400 and they are green lighted. Trim and model year are not important. Engine size and rotor size is. P400 with 20" wheels from the factory comes with the regular P400 rotors and calipers that I have.

From the site for part number above. Fitment detail of relevance

2020 Land Rover Defender 110 Base, First Edition, HSE, S, SE, X 2.0L L4 - Gas, 3.0L L6 - Electric\/Gas

Below is the full fitment list

Thank you!!! :-) Any specific 18" wheel / tire size I need to use? I don't plan on lifting... Just looking for more side-wall, and a bit more capability off road, and more choices for winter tires...

Type of wheel

Tuffant Simpson, EvoCoarse Dark Zero and Tuffant Kimberley are 3 I've seen done here. The caliper trim seems easier with the former two. I went with the latter and somewhat regret my choice. A good looking rim but a little more to grind.

AFAIK the caliper swap is doable with all of the above and more including discontinued Redbourne Alstons. It's a much smaller caliper. (equally as effective and safe per the strict Aussie DOT and LR Australia)

OEM steelies need spacers and trimming of the swapped calipers so that's a no for me.

Tire size without lift on 18's . Lots of options in R18 LT E (1 D) or XL load rating. Nominal sizes below

All R18 tires


265/70 are 32.6" and many users confirm fit in offsets close to OEM (I've gone for this)
275/65 are 32.1" and are very popular
285/60 I've seen on two users posts, both of who did the caliper grind. 31.5" I think so a little less sidewall with the wider tread
255/70 is OEM size. (KO2's run in this size at a D load so might be worth looking at too)

These will all fit without a lift. With the 265/70 being the tallest, be sure to check actual tire size specs rather than nominal listed here. Some can run bigger. 32.9" I've seen on some types in that size.

The no lift tire thread covers it a lot more but that's the meat and potatoes in the 18" rim no lift Defender.

Part numbers confirmed by a person who has swapped. They shared their part numbers with me. These are the parts for the caliper swap.

Thx again for the help, Gavin. I ordered a set of the 18" Kimberleys and the calipers. Now have to decide on what tires to get. Looks like the 275/65's are probably best bet, with no issues with rubbing during significant compression at standard height, according to the US Tuffant rep. As for tires, I am undecided what to put on the 18's, because I can still use the AT Wrangler Adventure 20's that came with the Defender. I DO want to get some good snows (I am in Wisconsin) but waffling back/forth whether to put some snows on the 20's (prob Michelin X-Ice), sell the Wranglers and put Falkens on the 18's, or leave the 20's as-is (with the Wranglers) and run those in summer and mostly street driving... During winter, or dedicated trips where I know I'll be off road, I could put the 18's on... Decision would be much easier if I could find a Unicorn AT tire that had great snow/wet and off-road performance that was quiet on road and handled well... My off-roading will be limited mostly to gravel/dirt roads (think Death Valley and White Mts in CA), deep sand (Northern AZ), and mud/snow we get here in WI. Another option would be to sell the 20's (wheels and tires) and get another set of 18" wheel's for dedicated snows...

No worries mate. Happy to be of some small help.

I run Blizzaks on my 20" in winter. I bloody love them. Grip for days. 275/55 R20. My Goodyears will go up for sale once I have them swapped off the rims in November. Not a bad tire, just not suitable for my needs.


Blizzaks in their element

Having a set of winter boots gives one more scope I reckon, to get the A/T or M/T that ticks all the summer boxes without worrying about the winter weaknesses of the tougher hard rubber compounds in the A/Ts

Look forward to seeing your Kimberleys. The really are a smart looking rim. (Biased ugly-baby syndrome here I guess)
