First, congratulations, you want regret.
Now for your mods, go for Seat Sport tail pipe. This is definitely the most classy and unique one.
For lowering go for Eibach E10-81-011-04-22. This lowers 35 front and 30 rear.
Exeo Sport pedals are nice, have those. You can get the rs4 cheaper, those are nice.too
This is only my opinion.
