sweeeet. thanks matt.

Yes, im running them in the front... i never tried them in ther rear, im using the stock rear axles, with the blue alm yoke bones in the rear.
i installed the TC4 bones a week after i got the car, (maybe 2nd week of april), been running the car with a front 1 way and we usually run twice a week, around 5 to 12 packs per day... so far, there is no visible wear on the bones... but i did notice some polishing of the TC4 bone where it contacts the steering knuckle, so i polished the innner portion of the stock knuckles.
in my opinion, this is the best option to use in front, in terms of durability, looks, and wear.

Hi Matt... is there another way to get bump-in steering without having to flip the turnbuckles...
why would the stock setting of the turnbuckle give more corner speed, if it actually bumps out during full lock?

Since the stock setting bumps out slightly, when the car corners hard the outside wheel will want to straighten slightly keeping the cars speed up and not scrubbbing it to make the corner. I'm talking about really small changes in the steering angle here, nothing major, just turn the wheels on your car and compress the suspension and you'll be able to see how much bumpsteer I'm talking about. It's just another small tuning option that myself and some others use.

BTW, Matt... thanks for the explanation. It definitely helps to know how the steering angles will affect setups. Thanks again!
