[QUOTE="toofast4u, post: 1836077, member: 3891"] I have felt that at the track when I run to little pressure in my rear tires. Actually one of my 555Rs had picked up a piece of steel on the track and aired down from 35 psi to 10 psi. It was not a good feeling going into a turn at speed when I really noticed it. I think you need to seriously examine your rear suspension and make sure everything is in spec and does not look damaged. The first thing I would expect are the toe links since they are very weak stock and a toe change at speed which could happen especially when hitting road imperfections will cause the issues you are describing. I replaced my end links with the ones my MM which also allow you to adjust bumpsteer which will also cause the issues you are describing, but I doubt bumpsteer is the cause of your problems unless you have really lowered your car a lot since the 03 have a revised inboard mounting location which dramatically reduced bumpsteer in comparison to previous models. After that it could be almost anything that is broken or loose and moving in the suspension. I wouldn't expect that, but you will get the one wheel spin which will cause issues especially with the power our cars are making. You can have the stock ones rebuild. Toe is the angle the tires are facing if you are looking straight down at them. If the front of the tire is facing outward of the rear that is toe-out and if the front of the tire is facing inward of the rear that is toe-in. Toe-in will increase high speed stability to a point. Toe is adjusted on the front and rear of our car and you should have toe-in between 0 and 1/16" per side. Depending on the suspension compliance, bushings and component rigidity, the toe is typically used to compensate for there deflection. As an example with the stock rubber bushings you want more toe-in then with much higher durometer Delrin bushings. Trust angle compares the angle the rear tires are facing in relation to the centerline of the vehicle. This can be adjusted to some point with the toe and should be as close to 0 degrees as possible. I have heard of some people having to move the IRS assembly to bring there thrust angle in spec. Solid axle cars that are way out have a real issue and using need to have the chassis straightened.
