    Mid Corner Steering Wheel Flutter/shake

    Ever since I bumped my camber over 2 degrees, the front digs in really nicely. The other thing it does is the steering wheel will shake in a sweeper and also when the car understeers. Am I lifting a tire? Does this sound like a travel issue?

    Front shocks wore out?

    Low tire pressures will also cause this.

    Caster is unknown, I got wildly inconsistent readings the last time I tried, but they seemed to imply I was in the 4 degree range. I found this odd as the lower adjustment slots were maxed out. I've since hogged out the upper mounts as well so I could hit my camber targets, currently running 2.3 there with 1/8 toe out and the front is doing its job for once. I need to drop spring out back to balance the car better, but it's pretty fast as it sits. I target 35-36psi hot as this seems to get the tires to roll over optimally and the temperatures across the face are consistent too. To optimize, the car seems to want more camber to be 15 degrees hotter on the inside but at this point I feel I need to address the rear spring rate first and also this newfound steering wheel shake. As for shocks, I don't know how to assess them on a race car

    Did you slot the lower adjustment slots or are they the stock length?

    Rubber bushings in the a arms?

    Front hubs gone?

    I still run stock bushings. Only time i've had front end shimmy was bad hubs or loose control arm bolt.

    Everything's slotted, stock hubs but a great brake pedal so I doubt they're to blame. It seems it does it when the tires break loose. Did it more with cycled out RA1s than not-yet-cycled out RRs. Lowers are the Global West heim kit (in good shape), uppers are new Moog rubbers.

    Steering rack/tire rod ends? Maybe it is the tires recovering...

    Let me drive if off track... I mean for a few hot laps and see.

    I see what you did there, but you know my car goes off road with this loose nut behind the wheel. So I did replace the steering rack with a functioning non-leaky junkyard unit prior to Hallett. There isn't any slop from what I can tell, is there some other mode of failure?
