So this past year I've spent countless dollars/ hours upgrading and testing my track car as I'm getting ready to race every event possible in 2020. I've had many roadblocks including overheating, brakes & many others. Well I have overcome those roadblocks and destroyed all of my past lap times and the car feels better than ever but now I have one last issue to work on. When I come into the braking zone at about 120mph the rear of the car lifts up and my rear passenger wheel locks up and is off of the ground a few inches. The car becomes very unstable and wants to swerve and pull to one side. This is causing me to have to brake lighter at the 400 foot mark while all of the porsches, lambos, ect. are braking at the 200 foot marker coming in around 120 -130mph. This is the only thing hurting my lap times at this point but I don't even know where to start without dumping $3000 experimenting with parts. I currently have stoptech big brakes with all stainless braided brake lines, motul rbf-600 brake fluid, & abs delete. My suspension is the Megan Racing EZ-II coilovers with the front dampers full stiffness and the rear about half. At the track someone suggested removing the rear sway bar. We did so and the rear wheels didn't lift up as much and the car felt a little better but more definitely needs to be done. Anyone with experience please share your knowledge!
