I agree with all you've just mentioned Sy
I'll be doing ALL the physical modifications before I even touch a remap this time around......
Brakes - I'll be looking at a lightweight style upgrade to keep the weight down. Hopefully I'll find something around the 300+mm 2 piece fronts with 4 pots and a very small increase in the rears. Maybe even wait and see what Audi put on the hot S1 or VW put on the PoloR.
Suspension - Looking at the B14 Bilstein coilovers, whiteline ARB's and engine mounts.
Exhaust - Blade's Milltek looks just right.
Intake - dunno yet, but something will go on!
Intercooler - maybe Forge.
Audio - I'll be going for an RNS510 most likely
Alloys - Most likely OZ Alleggerita's - drops 16kg off the rotational weight.
Battery - change for a Braille or RedTop one - Loses about 8kg.
Seats - Lightweight buckets and a retrim in Alcantara - Lose about 20kg.
So, only mild mods
