Welcome to the club!
I cant help you witht the dash bulbs.
The sporting's do come around 15mm lower than lower spec models iirc. If they are after market springs then they are likely to be either yellow/red..and should say on the spring!
Also i dont think they have an ICV, are there any other symptoms?
Post up a thread in the 16v sub forum and you will probably get a better answer in there!
Have you got any pics of the car?
