FYI   These rotors are equivalent to LR017953 & FTC1381 and should fit defender rear1987 onwards.   

And they are a good product too!!

Actually they DO NOT fit my '98 110 Bill....hehe, that's why I have two sets of them. I've imporperly ordered them twice now over the last 5 years :).

They are a 1/4" too shallow on their hub depth to run in a 110. These are right around 2" deep, the rear discs on my Camel are 2 1/4".

Now perhaps my Camel has some oddball setup?

There is a standard disc listed for the 110's, FTC3846G, that I believe is the correct one...er, I'm hoping at least, I don't need anymore that don't fit! :)

That said, these are a really good disc, if you've got the right rig for them!

Defenders did not have rear discs until mid 93.

They should fit Disco 1 and RRC though.

With the disco conversion Kits for the early 110's and defenders you could use disc brakes on the rear.   I just don't recall the details......

Found it!!!   FTC1381 was the part number that Colin used on his salsbury axle disc brake conversion....and I followed his lead ;-)

In fact.....I'll take a set of those rotors off your hands trevor!!!!!  Since I have the same ones I can keep them as spares and I think I use the same ones (EBC) ;D

Sounds good Bill,  1 set reserved for you. I'll bring them by when I come get my next BP order.

LR017951 FTC3846 BR1792R
110s to 1998.
298 mm diameter, 14 mm thick, 70.1 mm width.  Dimensions are the same as front discs, so I'm unsure as to why the different part number?

FTC1381 LR017953
Discovery 1 (all), Defender 90 (all, mid 1993 on), Range Rover Classic 86-95
290 mm diameter, 12.5 mm thick, 61.4 mm width.

SDB000330AP LR018026
110s - 1999+
298 mm diameter, 14 mm thick, 59.1 mm width. What is interesting here is they narrowed the discs.  I assume that they must have changed the caliper mount at the same time.

Well I am glad you have sorted the part numbers for 110 disc brakes.  Trevor's discs will not fit my 110 so I don't have to be  >:(  and annoyed that I just ordered new discs and find 2 of them could have been sitting in Trevor's garage all this time.  I ordered FTC3846G for my rear axle.
