New parts tested
ZS-008RW Rear Arms
I got the rear arms some weeks ago
but since I have had no place to practice all the testing was done at a
carpet race. The first thing you notice when you see the new arms is that
they are much beefier than the stock arms. They have 4 different holes
for the shock (2 upper, 2 lower) and the wheelbase is adjustable. The shorter
wheelbase setting is still a little bit longer than with the stock arms
and the longer wheelbase setting makes the wheelbase approx. 263mm. They
also have a molded ball stud for the roll bar. They will also make the
car slightly wider.
The new arms flex a lot less than
the stock composite arms. Therefore they will give the car more rear end
grip than the old ones. I also found the wheelbase adjustment possibility
very helpful as you can change the feeling of the car really easily by
just moving the spacer. By moving the hubs rearwards for a longer wheelbase
you also "move" the weight forward. So while the longer wheelbase makes
the car more stable you also get more weight on the front, which will give
more on power steering.
Overall I'm very happy with the new
rear arms. In a back to back test with the old ones they definitely improved
the car, at least on that track. They made the car a lot easier to drive
so just go ahead and try them. They're well worth it.
