OEM Brake calipers - aluminium vs cast iron

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😁

I have something to say............ It's better to burn out than to fade away..... :tt2:
