Induction kits (seen the AMD one, looks great but also like the forge twin intake stick to Revo best gains by far solid build too
Intercooler - upgrade the existing one? or keep it? (is it a FMIC standard?) yes it is an FMIC, i think you can go THS FMIC but that will cause more lag as you have lower pressure "IF" you plan on retaining your K04 if not then yes upgrade to the THS cooler
Mounts - engine mounts and dogbone mount go for VF engineering best mounts by far, got them fit last week they are just perfect
Bushes - polys all round or what?depending on the mileage really, im dong my suspension going for Bilstien b16 PSS9's with superpro cross members... Audi TT top mounts and bearing change ur sway bar links while ure at it along with ball joints
ARB's - what ones do they have as standard or upgrade these, if so to what?H&R rear sway bar 26mm dont get the front ARB will cause you issues.
Strut braces dont think there are any really
Brakes - what are they standard? (LCR had 4 pot brembos big discs) think they are 2 pot pistons
Exhaust - i will go resonated all the way as my cobra non res for the LCR was too loud - miltek the only or best option?, Best Bang for your buck really , there is super sprint but they are big money
DV - what are the option? think the forge is just noise really , just get the revision 'D' OEM if not mistaken
Software / remap - i had REVO stg 2 on the LCR loved it (linear) stick to them or AMD
other "must do mods" (on the LCR it was the rear wiper blade to the Fabia VRS one!) that sort of thing. LOBA motorsports fuel pump
im sure some one else would shed more light for you really as i come fro the S3 8L side of things
