Hi all , I need some information on the differences (dimensionally) between L/XT4 and XT6 rear disc backing plates .

 

From the manuals the disc rotor diameters are 226 , 256 , 266mm diameter for L/XT4 , XT6 , 1st Gen Legacy .

 

As I said in the above thread I am exploring the possibilities to see if XT6 type brakes can be made up without their unique components .

 

BTW I have the Aus reproduced rear hubs .

 

Cheers A .

Yes that would be fantastic if they are .

 

I reckon the way to tell would be to measure the inside of the dust cover section as XT6 disc rotors are supposed to measure 256mm diameter where L series and XT4 are 226mm . If the overall diameter of the XT6 plate is known I suppose that would be a good reference as well .

 

Fingers crossed , cheers Adrian .

i can measure mine for you. it's on the car, but i can take any external measurements of it that you want/need. just let me know, i need to swap my snow tires off of it anyway and will be doing so soon, easy access to measurements for you.

 

just get me exact details of what you want measured.

I've just measured up a beat up XT4 backplate and is approximately like this .

 

Overall diameter ~ 30cm .

 

The gap between the plates large middle hole and the half round section between the calipers mounting bolt holes 31.4mm .

 

The direct as in shortest distance between the caliper mount holes and the plates large middle hole - 48.8mm .

 

I expect the XT6 plates to be something like 20+mm larger overall and the other measurements approx 10+mm greater .

 

Cheers Adrian .

Subarutex , from the pic above and FSM's the XT6 ones seem to have a rolled lip on the outer edge facing outwards towards the disc rotor where the XT4 and L series ones are laid back at their outer edge (like a big shallow cone) towards the diff side (inner side) .

Also the stiffening "troughs" pressed into the outer stone guard section of the plate seem a lot deeper on XT6's than the 4 cylinder ones which are very shallow

 

I think these may be the way to tell the difference at a glance .

 

Can you let me know which you have please and do you use Paypal ?

Someone I know here gets bits sent in from the US for his V8 Dodge so should not be too difficult .

 

Cheers and thanks , Adrian .
