You make a good point. 170 though, awesome.

Did you only get the fronts done? From MRC's site I'm assuming the price is only for the fronts, is that right?

Also, did u need to change brake lines or did the stock ones connect?

Found out the hard way...you do need to change the brake lines as the standard S4 ones will be short. OEM RS5 or custom braided ones should do the trick. I went for the RS5 ones.

Worth mentioning that if you have 19 rotor alloys you will need atleast 5mm spacers to clear the centre of the alloy from the callipers.

And then you will need a set of 30mm longer wheel bolts to ensure everything is fixed securely. Not so straightforward as I thought.

I thought I'd also add to this thread as I'm running this kit and made some discoveries of my own.

Like the OP I'm currently running 18" S4 alloys (8x18 ET47) and they do clear the RS5 calipers, barely. You'll need at least a 5mm spacer to clear the spokes, although I'd recommend a 10mm hubcentric to be absolutely sure, and you end up with around 1mm clearance on the barrel of the wheel. The larger the spacer the more clearance you'll have inside the wheel though as the barrel tapers out towards the inside edge.

I think the ET on the 19 rotors is different so the 5mm spacer may give sufficient clearance. Or should I go for 10mm?
