I was having tons of bump-steer on my 210. Wasn't sure at all how to alter that (be nice to have some info in the manual; have any of you seen the Schumacher manuals, they have a huge tuning section specific to the car at the end?).
Anyways, tried this:

No luck with the stock set-up, still waaaaay too much with my 20 degrees of caster.
Tried the original RDRP steering rack; still tones of bump-steer, but I really didn't expect a change as it is the same as stock but doesn't suck (cheap plastic vs aluminum).
I tried the RDRP R2 rack; still tones (which, I read "does away with the need to use countless shims on the outer steering blocks in order to achieve zero bump steer"). I found the opposite. Plus, if I read this right, I loose A LOT of adjust ability:

Seems like wasted money (although, they say 25 degrees plus in their write-up vs my 20 deg.; I also want to add that it is the first item I've bought from RDRP that I didn't dig).
Now, from playing with every adjustment I could conceive, I found that zero washers on the steering arm (on the wheel end), and a 3mm washer between the ball-stud and the original RDRP steering plate has given me the least amount of bump-steer with 20 degrees of caster. Very little, but just/still a bit.
Am I doing something wrong; should other adjustments deliver different results? I wonder as most set-ups on Petit-RC show cars with 4-5mm spacers on the steering-arms (I tried this and found awful amounts of bump-steer - although I will say that most use 25-30 degrees of caster).
Love to hear your thoughts!
