Thanks for the advice. I'll keep driving the TB-02 for a while, so I should have time to tear down the TC-3.
Batjam, I wasn't planning on comparing the cars that night. I planned to run the TC3 and brought the TB-02 just in case. I practiced with the TC3, and ran the first qualifying heat with it until I hit a board and broke a front arm. So, I switched to the TB-02 for the second qualifier and picked up my pace by 2 laps (22 lap pace in the first qualifier, to 24 laps completed in the second).
So, I didn't go out to the track thinking "I'm going to compare a several year old TC3 with this brand spankin' new TB-02". But, the fact is, the TB-02 just drove so much better. I'm not saying it was faster, but it was much easier to drive, which in my hands meant I completed more laps.
So, I'm just trying to figure out if the TC3 is designed or set-up for a driver with more skill than me, or is something out of whack. What I'm hearing from all of you is something is probably out of whack.
As for the shocks, I recently re-built them with 50 wt oil in the fronts and 40 in the rear, kit springs: gold and silver.
The diffs are OK, I think. So, that leaves the bearings and hinge pins at either end of the suspension arms.
Thanks.
