Bought a 300mm rear disc conversion for 2wd cossie but the disc looks to far away when fitted. how think are the brackets and bells?

i think ive been sold the 4wd disc conversion whats the difference pics would be good please cheers

 

you got 4x4 calipers as 2wd ones wont fit.

 

measure the tickness of the disc
20mm means 4wd, 10mm means 2wd

 

It's even more simple than that, if the disc is vented, it is for 4x4 calliper, if it is a solid disc, then it is for 2wd calliper .

 

i gave him more credit than that mike

if it's a solid disc, make sure you've put 2 wheel nuts on to hold it tight against the hub face as sometimes this is the root cause of the disc not sitting flush and striaght and looking miles off

 

its a solid 300mm disc yes

 

this the the new disc compares just didint know if the bells for 4wd not 2wd or something

 

btt

 

i'd say that looked like a 4wd bel to me as it seems to flat for the 2wd version

can you put up some side by side pcitures please? as in from the side?

 

I thought the rear discs were interchangable with 2wd and 4wd so the depth of the bell should be the same, the only differance being the solid and vented part and the caliper being differant, i could be talking total bollocks though.

With the disc bolted on, there is not physically enoguh stretch in the flexy pipe to reach the caliper, that's the first problem.
The second problem is the caliper if it were fitted onto the disc with pads in etc, is so far away from the brake mounting lugs that the spacer is about 3/4 to 1" too thin, doesn't bridge the gap between the two let alone bolt up.
The disc bells imo are wrong and need to be set in a LOT more.

the discs look spanky

but ive been told..and seen drilled discs get cracks in them

each to there own opinion.. but just grooved discs for me

 

on the 4wd versions, all the extra width is towards the outside of the disc and caliper, the inner mountings and cables and pipes all stay in the smae position so there is no need to change anything at the factory
you keep the same hub setup but change the width of the caliper to allow it to clamp onto a wider disc = less faffing about when you want to upgrade as everything is just bolt in and away you go direct from the parts bin

agree with the pipe needing to be longer to fit over the top

i'm just wondering if someones not just bolted either the wrong bell to it or even just bolted the bell on the wrong way around

 

on my mates porche turbo thing, he actually melted the discs between the holes

but this is going back a good few years now when he first got the turbo version (around the same time as the 355 rari's were out because he was getting it fixed to part chop it in so no pics )

 

The bells are the problem as they don't sit in far enough.

Whose kit is it, as it is not one I have seen before?

 

not sure mikegot of ebay from someone who said they come of a 2wd
here side pic

 

Thats no where near right m8, wrong bell end of.

Steve

 

 

looks the same as the kit on my 2wd saff same brackets too just mine aint polished and they fit fine...
not sure on make tho...

 

Bells and brackets look like the correct ones to me as well....

 

what kit is yours?

anyone got a pic of the bracket fitted

 

On my computer at work I think .

 

which side does the countersunk part of the bracket sit?

 

4wd bell

the vents on the 4wd disc would bring it into the correct position on the hub

 

not got any pics of mine as car has been away for 4 months....
ive seen others on 2wd the same as mine too..

 

ok guys they do actually fit but need bigger brake lines.

Im just wondering why 2 holes in the brackets have deep countersunk in them and what way do they face when on the car as i originally though they were for the lugs on the caliper to sit but when i bolt it up the caliper sits at too much of a angle and wheel wont turn when i have them facing the inside of car its ok but still aint got a idea on how they go?

 

they may be countersunk because the bolts were allen bolts, to sit flush and not get in the way

 

you are right lol
just figured out why its because the norml nut is so close to caliper you cant get a socket in it when it turns so need to use allen key bolts lol
