Fabia vRS Combi 312mm brake conversion

Yup, about 8% less.

Its a funny debate / idea, personally I think the added weight is worth it. Addition of unsprung weight is only relative to the front wheels as its a fwd car.

I have 312's on the front of mine, have tried a few different sets of pads, etc. about to do the rears, I ended up with quattro carriers for the rears which don't fit (not even with the ECS spacer kit), propper ones just arived this week. I understand what people say about changing the pads, fluids, etc, but IMO the feel of the 312's is totally different to the stock front brakes which felt rubbish, even with better pads. Looking forward to the balanced set.

I don't agree with the percentages, or examples of what works on another car (eg software tweaking, I've not tried on mine). Brake feel is something somewhat personal, how do you measure feel in a percentage? I know when I use my brakes I barely have to touch them to quickly stop, worth the money over the stock system which always felt inadequate. The stock system could pull up just fine, but for feel and tracking (where the repetition of heat buildup makes little differences feel huge) the added bite really helps. Again, each to their own, the fastest Polo @ wakefield (owned by a person, not a tuning company) runs stock brakes with better pads, fluids, rotors, etc. There is much more to brakes than the rotor size, if I really wanted to do it properly, I'd ditch the basic single pot floating caliper design for something like the porsche 6 pot design (sexy and bitey).

Each to their own, for less than $1k I have a fully upgraded braking system to my needs, some will spend that on a nice set of pads, fluid and rotors.

Well I for one think you've improved the car and given yourself scope for further improvement down the track if need be.
