We've had a few requests for our setups, so I've attached the WRL baseline setup sheet and procedure below for reference. I did not draft these, but can ask our engineer, Jason to clarify if anybody has any questions.

Thank you. I finally got my own set of scales over the holidays, along with setup bars from Sebeco, and tackled my first full setup effort. See attached. Remember, I am just a hobbiest doing HPDE, so wanting an aggressive setup, but not wanting to scrape the track and set lap records. I want to bring the car home in one piece every weekend. I primarily run various TX tracks like Eagles, Cresson, and Cota - while venturing off to Road Atlanta, Barbers, and VIR.
I had a very difficult time iterating between desired ride height and corner balance. I would set ride height, then balance way off, adjust wheels for balance, then height off. I must have tried variations ~20 times and settled on whats shown. Notice, the right side on both F&R are higher than the left side to get balanced. What am I missing? Any advise or comments are welcome.

Let me run this past our engineer and see what he says.
Hi Dan,
Setting up a race car on a set up patch patch is often an exercise in ever decreasing circles until you arrive at an acceptable set up.
We always add 5 gallons of fuel and driver weight each time we set the car up.
Make sure you have the front and rear anti roll bars disconnected (so they are not adding a force into the car) and the bump and rebound on the dampers set to their minimum values (counting clicks anti clockwise until the stop). We also set our tires to their hot pressures.
Corner weights should be within 5lbs on the front ideally. We can usually get ours spot on and close on ride height. It is just a case of alternating between ride height and corner weight. We typically measure front ride height on the front left of the chassis using our bolt on digital caliper bracket. We also have a similar bracket at the rear for the SL82 gearbox which is close to the centerline.
A couple of extra notes - if your set up pad has roll on / roll off extensions its a good idea to move the car off and on after a change. I also like to firmly push down on each end of the car a few times.
looking at your notes it looks like the roll bars are connected? If that's the case they do need to be disconnected.
Thanks.

For clarification if it helps: The car did have 8.9 gallons for fuel, 225# in seat for drivers weight, roll bars disconnected and Hoosier hot pressures. I erroneously did not adjust the dampers for this exercise. My pads do have roll offs as well and I systematically did that each time after adjustments for the car to settle. At face value, it seems as thought I did most steps correctly, but still had difficulty as noted above. Hopefully it goes better next time.
