Scott, where did you get the engine cover from? Was it from a cupra TDI? looks spot on
312mm are good enough, i'm sure you can get them to fit, pop into a tuning specialist and ask them?
you will have to upload some photos scott thought you might like this little phrase from family guy.... "barrow..that is all"
I would have expected it to make slightly more bhp and torque with a map, not got much more than mine is pushing out lol
However, yours look the tits and mine needs lowering
Looks nice in candy white, effort to keep clean I guess, got metallic black and that requires a good eye.
Cheers id recommend them like, especially if you have them laying about, they are really good!
Edit: looks like you got 312mm in your sig?!
