Lowering on Eibach Pro kit springs
Spacers or maybe new wheels
Front splitter, rear diffuser, spoiler extension, side skirts
Rear sway bar
All the above are reversible
Currently have a JB4. Stage 1 tune is something I'm maybe thinking about, although I'm not sure if it's worth the outlay over the JB4 (never driven a Stage 1 car). I have to say I haven't been blown away with the JB4, I think the majority of the performance increase is at the top end which is hard to reach on the road. Maybe a Stg 1 tune is different?
I'd like to improve the sound as well. If I were to, then I might instead skip Stage 1 and add a downpipe, going to stage 2 with a TCU tune on top.
Obviously, I think the tune is the sticking point. It's reversible, but I would feel a bit guilty selling a car that's had a harder life than standard. Warranty is already gone though.
The idea is to basically reignite my passion for the car as the more I drive it, the more I just feel like I'm driving a Golf vs some of the other more aggressive cars I looked at changing to. Unfortunately, the two areas that were tempting me towards something like an M2C the most were engine note and drivetrain, which no amount of modding would change!!
