I thinks there's another member who complained about the reverse rake recently, that's why I've decided to go for the b14 as soon as I can afford it
TT rear spring pads are a quick and cheap way of sorting out reverse rake on the mk5/6 platform if needed 
I assume this will raise the rear up slightly, any idea how much?
Any particular year or model TT parts I ask for when buying from main dealer or euro?
Yeah it will raise the rear slightly, mk2 TT spring pads are twice the thickness of the golf (gti) version apparently 
Part number iirc is 8J0 512 149
Out of curiosity, is there an alternative to the TT spring pad that is thicker?
