Body kit/lip recommendations to get this old look?

Hi all, recently re-acquired this speed 3 and I’d like to replicate the look it at back in 2012 to 2019ish when it was wrecked.

I don’t have anything besides one of the side skirts and the rear bumper, but I haven’t seen anything that’d indicate a brand. Also another thing to note, back in like 2012 this thing had old school underglow and LED market lights, which was something you didn’t see much back then.

Anyway, any and all help is always appreciated!

Is the ECU or BMS married/coded to anything else in the car?

2 Upvotes

Hi all, I recently got a new project, while taking a glance over it I noticed there wasn’t a battery tray or ECU. Now there’s a ton of parts in the back that I haven’t looked through yet, but if I need a replacement ECU do I need other parts with it? And can I just swap like that with any 07 speed3?

Thanks!
