yea i took a risk with the length but luckily it paid off, and if they were too long i was gonna see if i could sell the bulbs and buy some short ones from HIDs4U or something.
i emailed the organiser too, he didnt know, i then spent a while finding some people who had it, a few measured bulbs and they were around the 46-47mm mark which i saw was what yours were so i was fairly confident they would be ok.
Ive been reading up about the goldeneye kit, its supposed to be very good for the price, lots of people bought them cos they were cheap but then were very impressed and said they were like a good german kit, so im looking forward to seeing the results myself
