Alllllright so yes, first time MINI owner and got to say, LOVE the car. AMAZING. Has changed my life. But, since I joined this site its gotta be obvious that now, I want more

So, to start off, I have a ClubmanS. Super awesome for a tall guy like myself, and love driving it. Never gets old. But, I want more. More power. More noise. More traction. More. More. More. So, I know the basics (worked on cars all my life) but the thing is, this is my first Euro car. So the engine bay, well lets face it, none exsistent compared to my old Honda. That being said, I will be getting some new tyres, upgrade the intake and exhaust, and chip it out. But I also want to know from any gear heads if there are other things I can do before I tear this motor apart, spend $10,00+, and make the super car I'm dreaming of. So, just wanted to introduce myself, and say GO MOTORING! Any advice is always great!
PS - are there any "kits" that can help to cut down on the weight of the car?
