I like to get my car feeling as neutral as possible, with the general amount of steering that I want, with all those settings still down "the middle". Then from THERE, you make the smaller changes to fine tune. Springs, Oil, weight, track, WB, caster... these are all the big guys.

Edit. Haven't tried laying shocks down yet, just because nobody does it like you said. Probably worth a try tho


I gotta get out to TRCR more!! the dang drive, AND bridge toll, always keeps me away. Maybe ill make it out this Friday.

I was thinking about getting "ION 2.2" M3 (Soft) Off-Road Buggy Rear Tires"

Should I use "ION 2.2" 4WD M3 (Soft) Off-Road Buggy Front Tires" in the front?

If you have the time, you could always cut down a set of 4wds to the width of a 2wd for testing.

Pretty sure you need the nut, but not the washer/spacers + ball.

A number of pages back there was mention of using the Exotek posts and the concern that there is now a metal-on-metal situation with the shock caps--curious what people experiences/thoughts are with this?
Might it be better to stay with the stock bushings?
Thanks

I dont think you need them. They should screw right into the screw which would eliminate the need for the little screw.
