Correct battery for 03 04 05 gt3 is 60ah part number 999 611 060 20
manufactures of battery and battery codes vary depending on the country code and exact time of built.
Also if you 've ordered the car with a/c delete and radio delete it came with a 50ah battery. part 999 611 053 20



ps I didn't read the whole thread but whatever you do, don't buy a braille lightweight battery; they are terrible and the after-sales is a disaster.
I bought the B2317 for my lightweight project and it ruined my alternator in 5 days. Then the battery died. Sent 5 mails to the company and they never replied.
So they deserve this.. Thanks for reading.

Sorry for resurrecting this old thread but I just wanted to mention that Optima no longer provide the euro brackets at all.

ust want to save someone else the time/hassle/expense before ordering an Optima and expecting to get adapters to help it fit.
