- Exhaust Honestly, I don't want her too loud. The only consideration for me was flow rates - so any decent system with high-flow cats, but still enough to pass unnoticed in day-to-day driving (Well, until I put my foot down at least...)
- Blow-off valve — I don't have a gauge in at the moment (another little side project for one day) so I'm not certain exactly what the turbo is doing, or how well the system is holding pressure. So maybe that gauge, then tune, then valve if required.
- Front-mount intercooler Intercooler was always a maybe thing. I had a feeling that would be the case. I haven't got her hot and bothered yet, and temp stays rock-solidly in the centre of the gauge. So intercooler is off the list.
- Tune I remember Kido being mentioned alongside Matt McLeod and others on other posts, so they're high on my list of places to look at for the tune.
- Carbon Fibre scoop I'll definitely take photos / video of it being done then. It'll take some fairly precise cutting, I know that much already...
- Boot spoiler retrofit Yeah, she feels a bit bare without one. I'm considering pricing up a stealership for both a stock one fitted and DIY kit. I'd prefer to not make holes if I can avoid it, but if it's ridiculously expensive I might even find one on a donor car if one exists somewhere.
- LED interior lighting, and colour match front sidelights to HIDs Ready-made LED lights for the interior are commonplace, and there's already a thread on LED colour matching sidelights to HID headlights on this forum. Link: http://forum.liberty.asn.au/viewtopic.php?f=20&t=29541
- Gutter rash I've been suggested to repair rather than replace. Maybe factory GTB rims painted STI dark grey would set it apart on the cheap. some paint codes have been listed here: http://forum.liberty.asn.au/viewtopic.php?f=2&t=30321
- Bluetooth add-on - McIntosh definitely heard about the GROM IPD-3 with BT kit, when even the factory 3.5mm stereo jack kit is $220, the Grom for up to $400 depending on configuration is actually quite reasonably priced.
Thanks for your input Shav, muchly appreciated

. I'll keep that in mind too about the exhaust, only swapping out the dump pipe, would save some coin, and I imagine keep her quiet. Thanks for pointing me to Ultrex, seems they read my mind and have the carbon fibre bonnet scoop inserts; they have them pre-made as well as a lip spoiler and a blank carbon fibre surround mesh insert front grille... Seems your warning came too late Tien! So many things to spend money on... I might still try the wrap option for the current grille, see how it goes, because it will be cheaper than the aftermarket bolt-in part, but if I fail dismally, it's good to know the option's there. Cheers Shav.
It is good to know that the unit can be used with the steering controls. How does it go with call handling? And is it painful to mount the mic up in the A-pillar? Hmm. Plenty to think about. I was actually leaning more towards the Ultrex spoiler linked by Shav, I just prefer the way the other ones extend past the boot to cover the rest of the arse end...
