So, I went back to Walmart and got an additional 25lbs of weight plates, for a total of 70lbs. I'm glad I asked for the re-evaluation of this car because I'm not installing an additional 30lbs. Before I started drilling holes I decided to move my fire bottle closer to the tunnel to allow the weights to be closer to the outside. I put the 50lb stack to the rear, and the 20lb stack just ahead. Then I started the ballancing again. When it was close I went ahead and marked then drilled the holes, bolted the weights in place, and futzed with the corner balance one last time. The results with a full 12 gallon tank are 2818lbs total, so I can use all but about the last 3 gallons of fuel and make weight. The final corners are: LF: 700lbs RF: 700lbs RR: 700lbs and LR: 718lbs. So, I'm starting out slightly tail heavy, but by a half tank I'll be a little nose heavy. I've also decided to go back to the oe sway bar on the rear, it's tiny like about a 1/2" bar, but it'll allow me to continue running my 550lbs/in rear springs instead of purchasing a set of 600 or 650 springs. I was running with out the rear bar, but I think the car was running a little tight, while the adjustable bar I was running on full soft was a little loose. My next race is this weekend, I'll be running ITR and STU, wish me luck :026:
STU BMW Z3 2.5liter
Thanks to all who wished me luck because I scored my first first, in STU. It was a well fought race aginst David Allen in an e-30.

What you won't see is my car overheating ending my weekend. I've since pulled the head and discovered a very slightly burned head gasket.
STU BMW Z3 2.5liter
Yes - or at least 1/16" When I used to have weigh in my car (200 lb. or so) I used a rectangular plate that was about 8" x 3", with the two mounting holes about 5" apart (the weights were made about 10" x 6" and came from a stock car shop and were pre-drilled). Underneath the floor I used large and strong fender washers.
You don't want that s&*t coming loose when you roll the car!
