Can I ask, what size tyres you have on your car, and as it been lowered?
agree with Rich's post, you have the wrong profile. Falkens452's on mine and its not been lowered. Also my rear wheels are 11" wide so can go bigger than 275

I would go and get a laser alignment done and wheels balanced. Hunter systems are highly regarded for laser alignment. Check out there werbsite for a local opertaor
I also have no issues with EBC grooved discs. I haven't tracked them though and have no intention of doing so. I will say though that HEL braided lines is a great improvement for a small outlay
you can do a ECU reset. Check the guides section. This will clear the fault error and the light on the dash will go off.
As above, take it back to where you bought it and get it checked properly. the crank sensor could be on its ways out so get them to foot the bill
or R35LEE for a second hand part and if you dont want to fit it yourself then pop into Lockwood and Greenwood. Speak to Dave on the service desk and he'll look after you and give you some club discount
