Want to upgrade (as topic title suggests!) but have been having a few issues:

1) I have a 2003 import sti, which has separate low and high beam bulbs - and everything i read says it should have a single dip/high H4 - can anyone advise on this because what i can physically see and what im reading are two different things!

2) i have been told that something to do with the wiring on subaru's restricts the initial ampage needed for the ballast to turn on the hid and therefore they wont turn on - again is this true?

If anyone can advise me on what i need/where i can get it from (links much appriciated!)

Cheers guys

A little early for my experience unfortunatly but hopefully someone who is familiar with that year can help

Sorry I can't help either I've not done it only changed the headlights to after market. Bug has morretes and the blobeye is an aftermarket set off fleebay with LED side lights. never done a full HID conversion . I did read a little bit but like Jay said about the MOT I gave up on the idea as I didn't know enough and had other thing's in the to do pipeline at the time :D 

I had hid's on mine they were plug ɑnd play! Took em out ɑnd went back to standard, would say you could have em but I binned em

Jonny can you remember where you got them from? What bulb type they were etc?

I was speaking to a chap today about this who's MOT did fail because they didn't adjust  That was a Mk2 Focus though 

Jonny can you remember where you got them from? What bulb type they were etc?

Iam back at work on Thursday I think they may still be in my mates workshop so I'll find out, don't know where they came from. They were on the car when I got ιt! They are good but I don't lιke them
