I am not familiar with the Street beast door hinges. Are they two curved tubular steel pieces with a single 1/2 inch bolt running through them for a hinge pin? The type I am talking above use a mounted plate that is welded to the door side. They attach to the door by drilling, taping and then bolting the hinge plate to the door. This is a common type of hinge used on many kits.
The problem is that there is alot of play in the hinge pin. This is because common diameter tubing is used instead of a precisely machined part. To elimintate the play I drilled a 1/4 in hole through both upper and lower hinges. I drilled the hole in the center of the the arc. I took a piece of 1/4 inch threaded rod and threaded on a nut and slid on a flat washer. I then inserted this assmembly between the upper and lower hinges and backed off the nuts until the rod was tight between the hinges. I snugged the nuts down until the slack was taken out of the hinge. This eliminated all door droop. I also drilled a small hole and pinned the hinge to the frame mounting plate to eliminate the possibility of the plate moving. I keep the hinge pin lubricated with a spray graphite to keep it from wearing excessively.
For those people that want or need really roomy footboxes and cocpits my new Cobra chassis frame/body kit offers that. I am 6'2" tall and weigh 230Lbs. With the seat fully rearward I can not reach the pedals in my car. And my Cobra is the stock width and 90 inch wheelbase. If interested you can check it out at
