Interesting take on the physical steering limit screws. It makes sense, too. Another rc car with a similar problem is the Kyosho Scorpion. The inside wheel at full lock can actually achieve a straight line between the steering link and steering pivot.
Being as Teknos are front-heavy by design, I think the case is even stronger for a misprint.
Unless the idea is something like the forward weight bias requires harder front springs, which requires thicker fluids, which would mean the larger holes are required?
Have you compared it to other...
The 410 2.0 and 410 SL probably compare like the 410.3 and 410 SL do. One is heavier with 1/8 buggy construction, the other is lighter with 1/10 style components.
