Top recommended performance accessories for the Jaguar F-TYPE R-75?

So I finally took the plunge and picked up a Giola Green R-75 last month and honestly I am in love with the thing but you know how it goes... once you get used to the power you start looking for that extra 5 or 10 percent. I am based over in the Cotswolds so I have some decent backroads to play with and I am planning a massive road trip through the Swiss Alps this August so I want the car feeling really sharp before then.

I have been digging through the forums and saw a lot of talk about the VelocityAP stage 1 tunes and their crank pulleys but I am a bit paranoid about the warranty since this is the final edition model and I dont want to mess up my coverage this early on. Also looked at the Eventuri carbon intakes because they look incredible but then I read a few posts saying the stock airboxes are actually pretty efficient and it is mostly just a noise upgrade for two grand which seems a bit much for no real gains?

I have got about 3500 quid set aside for some initial bits and pieces. Should I be looking at lowering springs or maybe some different spacers to help with the stance first or is there a specific exhaust mod that doesnt drone but lets that V8 scream a bit more? Just trying to figure out what actually makes a difference vs what is just hype. What are you guys actually running on the R-75 specifically?
