Not broken. The company who built my steel 1-piece DS did a great job but the shaft was 3/4" too long. Not a 'mistake' and not their fault. It's not something Adam would have even noticed cause it wasn't until the whole rear was torn a part and the DS was out that the problem was discovered.
With it being too long, the shaft was bunching up the trans and motor. You could easily see where the shaft was literally banging against everything and when the car was under load, the power was bunching up in the rear and screwing everything up. I'm actually surprised I pulled the 60's that I did with it the way it was working. The shaft was cut 3/4" and now the power goes straight to the tires and transfers perfectly. The shop that dialed in my rear and suspension noticed the flaws when they took my rear a part to weld my axle tubes and put in c-clip eliminators. With the exception of my rear shocks(which I picked out), they liked the parts that Adam had recommended for the car but the DS being too long was really not allowing the parts to do their job. Some changes to the pinion angle and some other stuff and the rear was dialed in. Meticulous alignment was the finishing touches. On the brake, if I can hook this power (which I should now) I'm excited to see the results. I've also taken over 150 lbs that was in front of the axles and moved it behind the axles. I've shaved over another 100 lbs altogether without cutting up anything. They worked a lot of tricks that shaved weight I couldn't believe. There is almost 100 lbs under your spare tire well that can be shaved believe it or not by stuff that doesn't even look like it weighs anything.
There was also a nice trick to remove the exhaust heat that goes into the supercharger while the car is idling that tricks the sensor to think its' still doing it's job. Really cool stuff and I'm excited. I'll have lot's of build pics in the next week or so. I've been taking pics and documenting a lot of stuff and I'm just waiting to put them all together in a single build thread.
