Porsche Caliper Conversion

[mike_tt 2018]

Hi guys + girls.

My  2002 audi TT Roadster breaks need a little more bite to them i feel. I've upgrade my disc, pads, + hoses already [Mtec drilled + grooved discs, EBC Redstuff pads and Mtec braided hoses all round], but it's still not enough. I've heard people have put Porsche Boxster calipers on their TT's? But I can't find any info on what model of boxster or year? i.e a 2.7 or 3.2 ltr?

An I can't find any info on how to fit them..is their any complications, or conversion kits i need to get? 

i found this conversion kit: https://www.awesomegti.com/shop-by-car/audi/a3-8l/vagbremtechnic-front-brake-adaption-kit-allows-fitment-of-porsche-boxster-calipers-to-312mm-oe-discs/ 

but I don't know if i need it?

I found these break calipers on Ebay: https://www.ebay.co.uk/itm/112977968816?ul_noapp=true 

and the advert says that the calipers are able to take 312mm discs - which is what's on my TT.

Can anyone give me any guidance please?

 Any help is greatly appreciated.
