Been looing for a replacement clutch for my 99 uk turbo

I recently replaced the gearbox with one from a 98 version code TY752VN6AA

I have been looking at clutch kits and have seen 2 that say they are for the 99 version impreza 2.0 turbo. only thing is they are both different sizes.

one is 225mm the other is 230mm are they both compatible? if so why the 5mm difference.

any help would be great and here are the two in question..

many thanks in advance!

 

99 5spd car was only ever fitted with a 230mm clutch as std.....

225mm clutch was only fitted to early classics
