When i bought the car it already had extended studs which was nice, but today one of em broke in the rear passenger side and i was wondering what kind of brand they are to replace the whole thing to match the other three. Here are some pictures if anyone can recognize what brand they are thanks in advance ! Btw they are 2 and a half inches long... i didnt have something to measure in millimeters.

 

No idea of brand but arp makes good extended studs.
