1984 626, need some info
 

Here is my ride Link
Built in 1984, engine 1987, 2000ccm, 75kw


I need answers:

1. Original rims specifications (Hole circle code) and i want to know is there any more popular car with the same specifications
2. Original factory tire size?
3. Tuning info, simplest way... I've searched the internet but it's not very popular ride
4. I need some pictures of modified rides, so if you have the same ride, plase post or send me photos or links

Thanks
