For the front C hubs, i put 4mm 0.2mm thick shims on the turning pins so it stops the wheel hop that the car had. The front wheels after 2 runs are still very tight, and the car is actually quieter and is more responsive and less twitchy.

I can't post pictures yet, but when i can, i'll share everything i've done. I ordered more RPM cups to tighten the suspension, and my main chassis is too weak and tweaked.

Future mods:
EXOTEK Carbon fiber chassis, should get it next week.
and
Pro 4 suspension parts.
