Get some instruction. Proper performance instruction, preferably on an airfield or track so you can really push it.
Next, get a decent geo setup. Not just the wheels pointing straight, but go somewhere who can tailor your car to do what you want it to.
Then get some better boots. MPSS, will make a massive difference again. Also get some Rays on, £500 and you will notice the difference.
If, after all that you still aren't enjoying the car, then it's probably not the right car for you.
