Megane Scenic 1.6 16v TRW Calipers for SWAP to Clio Williams brakes

Hi!
I am not satisfied with the braking performance of my Clio Williams brakes system.
First, I bought four-piston Brembo front calipers from a Peugeot 406 3.0 V6 - but they didn't fit the Speedline Williams wheels-so large.
My mechanic advised me that the front brake calipers from the Mégane Scenic 1.6 16v (TRW system) would fit without modifications, plus the 280mm discs and plates for this car. Is it true? Will it fit without modification?
Here this what I want buy:


And I have yet one question, I heard EBC isnt good products?! Whats your opinion?
Thanks

Hi Sova,
I have checked the links, those brake calipers are standard one for 259mm diameter of the disc.
It would maybe better to check for the scenic2,0 16V brake calipers for the 280mm discs. (I am trying to solve the same issue - got clio 172 brake calipers and would like to have some bigger discs 280 mm on mine williams - but i think there will be needed some adapter for it...
