the Accord clutch has 'printed' a different value on the pressure plate than the 325 set. as far as i remember it's 6600 vs 7500. I believe this is the spring pressure power in Newtons (N).
These clutches in i-dtec accords have been coping with software modifications of 210PS/450Nm.
I also know from polish accord forum that many people have installed the Type S Accord (factory 180HP/380Nm) clutch for 'regular i-DTEC Accords (150HP/350Nm) without any modifications at dealerships, because the regular clutch was slipping and it helped.
I made some pictures of the Type S clutch, also in comparison with regular Civic set
The pressure plate appears to be deeper on the Idtec? I presume it requires milling but where exactly did you remove the material from?
