Drove the car around the block this morning, ran smooth and pulled hard. Took a log of that and sent it to Haltech, hopefully they can tell some difference between the two.
Recently finished these taller castle nuts, don't think I'd posted a picture yet. We had one strip out on one of B's ball joints a while back and it could have been a lot worse had we been going over a walking pace. About twice the thread engagement if you don't count the castellated part. 4340 steel, need to check hardness vs the stock ones when I get my hardness tester back, might get them heat treated. Since we normally have to use a washer or two under the stock castle nuts with our fabricated control arms these fit instead without washers. Put one on the Impreza when we reassembled it.
