As per the "what did you do" thread I had to source a pair of replacement front calipers today, as mine have seized on the lower inner piston on both sides.
After searching the 'net, I found a couple suppliers had them in stock. First being Torquen - albeit at over £600 for a pair for either cast iron or aluminium.. Then I found some fully rebuilt aluminium ones (the correct fitting for a TT) at less than half that, which got me thinking. Cast iron vs aluminium....??
Both seem to have their merits and drawbacks - the ali ones being much lighter, so less unsprung weight - whereas the iron ones allegedly handle the heat better, reducing the chance of disc warpage. If one believes everything one reads on the interweb LOL!
Seeing as I don't track the Zed - and I am happy with the OEM set-up, when it works properly, plus I have a set of Brembo discs waiting to go on, as opposed to the Ebay ones I had previously, I thought the ali calipers would suffice.
Opinions please - good or bad😁

A Little Help Please!!
How do you use a boost leak tester, Im not getting full boost until way up the rev range and even then its not really at max (stock gauge mind you).
I presume you do more than remove the filter and MAF and just connect
to intake pipe and pump away right? ;)
thx guys :bow:
