Your 2 cents is growing old. Bill Reilly the owner of RMS, lives right down the road. Call him up and ask him if my car is bent, he's going to tell you I installed it in a rush.
Here I am, trying to throw out there, what I've found out by experience with this product., and how you have to be very careful installing it. What the pitfalls could be. So people who are buying it know that these things can happen. You keep adding to this with what info ? Do you have a QA1, or are you basing your non-constructive advice on nothing ? Tell me how you get the Damn thing perfect, so everybody here that might potentially buy this, can have some confidence in this product. Share you expertise. Not, sand down the torsion bars. Did you know spring steel is stress relieved before it cools ?, did you know a grinder, and sanding disc can cause stress rises even under minimum heat, if done wrong ?, and take away from it's rated yield. You could buy torsion bars rated for 200 lbs, and end up with 2 different ratings. Do i need to post a link on spring steel metallurgy ?, there's a good one from one of the biggest steel automotive manufactures in the country.
The stock factory piece has a conical seat on the head of the bolt, to fix the K member in place. QA1 has nothing, you have to find the centering by measuring, and luck, or fixing it in place, than bolting it up.
When your done why don't we put hi-jackers on the backs of our cars, and drill holes in our exhaust too.
