Has anyone on here fitted 330mm discs and the equivalent calipers to a 2.0lt, and have they any advice, images, or step-by step guide ?

I have been looking at the 'How-to: Cheap brake upgrade' which is helpful for What parts to get,
but im find it confusing how to actually go about fitting them? :(
I have a 2007 2.0lt M Sport with 18" MV2 wheels.

Is it ok to just change the fronts? Will this MASSIVELY upset braking?
Im not too worried abut the current braking performance, its mainly for looks (with the added advantages of some increased stopping power if need be).
 
I'm sure it would be fine to change fronts only. With the MV2s though, you can't really see the brakes that much anyway. I'd maybe be more concerned with the increased unsprung weight with them.
 
I made a similar change to my 2.5 and the balance was fine. I later upgraded the rears as I was disappointed with the improvement in performance - although it may be more significant in the lighter 2.0, but the BMW brakes just aren't very good hence all the ///M drivers going for BBKs. For better feel and stopping power when you need it go with upgraded hoses, fluid and possibly some decent pads.

+1 with the bigger callipers and disks it adds up to quite a lot.

ADD: The bigger brakes do look nice though, but don't forget you're adding also to the insurance, future disk and pad replacement costs.
 
Not much difference in the parts cost.just buy E46 badged bits as they are usually cheaper :D
insurers didn't care on mine as they are the same as the facelift.
Unstrung weight is an issue but stopping on a big is more important. May be more critical on the 2.0, so don't go massive on disks and calipers.
 
Definately doesn't upset braking.. I've got standard rears then 356 8pot fronts, the fronts do most of the braking on all systems

In regards to unsprung weight is it not the same suspension system as the larger engine models
