Its got gaz shocks and springs, lowered by 45mm at the front and 35mm at the rear, 17" wheels (205/40 zr17) and a rear strut brace. I think stiffer suspension would help it quite a lot but don't really want to spend anymore money on it!
I spent approx £200 on petrol. Overnight ferry, food on the ferry there and back, and hotel for one night in germany was £165. Track time was 19euros a lap or you could buy in bulk, I bought four laps for 64euros, approx £50! And then little bit of food while we were there and drinks on the ferry , depends were you eat but £60 should cover it! I took a bit more than that and bought a couple a stickers (5 euros, £3.50) and a nurburgring t-shirt (45 euros £30), just for souveniers! Basically £500 sould cover it each if a few of you go and share rooms! Hope that helps!
