been offered a set of 2 piece discs for the rear of my lcr cheap, will they fit, what is needed if so, i know they will fit a tt and r32 but not sure about lcr????
will 308mm x 22mm rear discs fit lcr

They look good mate,doesnt tt run same rear brake set up as LCR,so if they fit a tt then they should fit,but rears dont do much,id be a bit worried about increasing rear brake performance by alot,it may increase chance of locking rears up and make rear end feel abit unstable.
I am looking at getting exactly these. Where are you getting them from 'cheap' ? 
Pretty sure they will fit, maybe there is some grinding needed and also I am worried about the length of the handbrake cable - as with the spacers you would either need to adjust the cable or get a longer one...

Exactly why you shouldn't realy modify rear braking setups. The LCR doesn't allow you to alter the brake bias and too much rear brake bias is potentially dangerous. Forget about straight line braking, locking up the wheels then is bad enough but too much braking force at the rear when trailing the brakes in to a corner is a recipe for disaster.
So basically upgrading the rear brakes is a bad idea. The only time you should upgrade the back is to maintain the original brake bias when significantly upgrading the front. This shouldn't be treated as a hit n miss affair it's something that should only be done by a brake specialist. Generally speaking, leave it to the brake manufacturers and buy the recommended rear brakes that match a pair of front brakes.

Ive you run motul CBF600 racing fluid and DS2500 pads and the 330x28 big brake conversion like the one im upgrading to soon as supplied by Bill at Badger 5 then these rear discs should be ok as the front has been upgraded to be quite superior to the std ones. As im lead to believe its not the Brembos on the LCR it the std discs and pads that are poor. Afterall Brembo is probably one of the best brake caliper manufactures ever.

this is all it says, some customer bought them and didnt turn up for them, they are £200, does that seem good
ECS Stage I Rear Upgrade Kit, Slotted & Zinc Or Cadmium Plated
Bolt-on complete kit, Does not include pads
Finally a big brake upgrade for the rear of your, r32, or TT Quattro. The ECS Tuning Stage 1R - Vented 12.1" Big Brake kit features a 308x22mm vented 2 piece directional vane light weight rotor and custom zinc or cadmium platted steel hardware. By retaining the use of the stock caliper we are able to keep the price low and retain a parking brake.
(Please note some R32s will require grinding of the housing surface of the spindle.)

Standard LCR rears are what? 256mm ? standard fronts 323mm assuming no changes in caliper and pad/disc performance that's a front/back ratio of 1 : 0.8
All other things being equal, the braking force is proportional to the radius of the disc. So given the ratio of the two standard disc sizes above, even an upgrade to 330mm fronts will only require an increase in rear brake diameter to around 260mm. A 308mm rear is significantly larger than that. In fact it's18.5% larger, which will mean 18.5% more braking torque. If we use an example of a car where the front:rear bias is 70%:30% then increasing the rear by 18.5% will give a final front:rear bias of 66%:34% - a considerable difference in balance from original.
Personally I would never fit rears this big on a car like the LCR, you'd need something in the order of 388mm fronts to justify such a large rear disc.

then the ABS kicks in - but much earlier than it should
why would it when the speed sensor and pick up is still the same?
because the rear will lock up....
try braking 'quite hard' and yank the handbrake up... ABS will kick in.

I wouldnt bother spending alot of money on rears,when you are braking hard with weight transfer all the braking requirement is needed at the front,i know the LCR has vented rear discs so seat must think the rears do a fair bit but when youve been out for a good hard drive front discs are red hot but rears are only fairly warm which tells me they arnt doing much work.
think about it...
same force, more distance = greater moment
the greater the moment, the harder it will try to stop the wheel. It's physics.... and sodding obvious.

momentarily it will. then release. the lock up. then release - but all far too prematurely.
That's how ABS works.
So you won't slow down as quickly.
I feel like you should know this (but then Mk2 escrotes don't run ABS)
