Tq is excellent. Avid was prety good. I got burnt by fedex but wasn't avids fault. Basically paid $80 for $45 worth of bearings. Definitly usps nexttime.
As with most bearings clean em.out with brakleen before installing with a single drop of light bearing oil. My avid ceramics were awesome but they did come packed in grease.
Everyone gets in thinking they can just do it cheap and be happy. I picjed up a used futaba and associated in 2011 for $600. I've since spent probably 6grand across all my platforms plus vrc lol.
For steering blocks, I know t2/3 blocks drop right in. I had to shim them to match the height of my spec r but I have one in my s1 and a stock one heh. I'm gonna try a t4 block. Basically any tc with two 5x10 bearings per axle should work with shimming.
