Thread: P11 Auto-X Setup help

Thanks! Trying a ting. The panhard mod completely changes the character and I forget that it is a bean behind there.

so I adjusted the lower control arms to 15". Did not take any measurments before I changed it but I would say it is around 3/8" shorter. Also drilled the uca mount to lower the mount point for the uca only for now. Initial camber is -2.1 which is great and steering feels a lot more responsive as well. Also got 255 nankang ns2r all around so we will see how it does next event coming this weekend.

Just wanted to update you in regards to the bump steer. I found out that I had a bad rear hub bearing on the left side which was causing my car to follow the road. Replaced it and now i dont notice much bump steer now, would say it is about the same as before.

Nice! That's great to hear. Was the bearing making noise or did it have play? Mine are not making noise, but I have measured enough runout that makes me think they are going too. With Toe plates my rear toe will vary +/- 1/8", which is kind of crazy, but not bad enough to make me wanna pay $200.

It made no noise what so ever and movement was actually really bad. what gave it away was i stated to hear a click when applying the brakes, so i went to inspect the pads(or shoes in my case) and saw the hub moving about when taking the brakes apart. I never noticed the movement before because when working on the rears the had brake is always engaged and would hold the hub in place.

Haha I can attest to that, handbrake is usually up when I'm working in the rear too.

I wonder if I could just press my hub back in then, since bearing doesn't seem shot.

With the stickier tires the hubs will wear down faster so that might not work. just my 2 cents but still worth a try.

Figured i would update this a bit, still working on the old lady. Cut the front radiator support and made my own with some tubing. lighter and stronger. win win.


I also cut off the rear LCA bushing and replaced with a spherical joint. This is the first test setup with way too much anti lift, I have since added a spacer to the bracket and moved the bearing on top. i also have multiple holes to adjust caster.
not shown here but i also got spherical out tie rods and drilled the hub for a straight thru bolts. One thing to note is when I did the out tie rods with the UCA inner mount redrilled mounting holes, it had way to much camber gain for my car at least and car was all over the road. Change back to stock location with UCA and boom, works real good.

Thats awesome! How much caster and camber are you running currently? I've also been playing with geometry... these cars really want more caster.

I dont have any real way to measure caster, what do you do to measure it? Camber is currently -2* which is cool considering I changed back the mounting location for the UCA back to stock, before it was around 4*. Camber stays the same at 2* when turning the wheel all the way.
