Rear hub with 928 bearing and increased offset, 928 Hybrid trailing arm, 944 brakes, extended hub offset, parking brak Options

[Wilhelm]

Few pics of a project I'm working on to break up the misery or paint, bondo and rust removal on my V-8 SBC conversion. I'm going to do the sheridan body work on my car and found these wheels which I liked.




The problem is the wheels are 10 inches wide with an offset of 2 inches. In searching the web site it seems that most people with this combo have gone with 3" spacers. This seemed like it would put a lot of force on the bearing and I still would not have many other rear brake options. So.... I found some rear 928 hubs on ebay. the bearings are much larger: 85mm diameter and 47mm wide (versus stock 75mm diameter x 37mm long) and this would provide me with other 5 lug rear brake options. So off to the barn.



First, put a piece of 5 inch 1.25 inch wall DOM(Drawn Over Mandrel steel tubing) in the lathe.

I don't know why this additional challenge occured to me yesterday but I really appreciate you'all sharing your solutions as they are great.

I wonder if the wilwood caliper or the pads are already heated up and have expanded more than the rotor when the brake is set and therefore the pads are bound up from the rotor not shrinking as much as the caliper? If it does happen and you do get it loose you might try a cushion spacer of some type under the stationary pad to keep it from being bound up on cooling, maybe even a warped washer ( I don't remember their real name)

It could also be the flexing of the mounting bracket from the leverage applied to the arm. I am sure you can figgure it out and make them work.

I know it's a pain but if it does lock up you might try jacking up the car and loosening the wheel and rotor and it might save beating the caliper up.

Both solutions look great to me.

I am going to try to move the 914 bearing housing out ward andrefabing the arm or a copy of the arm out to it to try and not have the stub axle so far up in the bearing housing, this may prove to be easier said than done. I currently think the 914 bearings are large enough. I already have the 911 brake and stub stuff and it looks to be enough brake for a hot suby in this light car to me.

I think it's better to have more heat than filler than more filler than heat.
My previous experience with torch welding helped me on my curve with tig. I don't have any grip in my left hand so I have to stop and reposition the wire pretty often so that is my challenge. My best friend is a welder and fabber by trade so I have all the advice I will ever need. His beads are almost robot perfect.

I guess my search abilities are not real good as I missed this yesterday when I was starting this solution search.
