Even if GM go out of business, you can still get an FLM chassis, or use the stock item until something else comes along.

With the 3905 tranny, you have to use the stock slipper as the RR or Strobe version only fits the older 3906 tranny- just tighten it up 99% and you should be fine.

As for suspension, thats very much personal choice. If you were deciding between just RPM and stock, I would go with RPM. Otherwise, there are many different aluminium suspension options- RPM arms and towers dont give you many options for tuning your ride height..

As for batteries, 4s lipo is fine for upto about 35-40mph with the MMM system, or if you want a bit more silly speed then 5 or 6s lipo. 5s lipo is alot of fun for bashing I've found, and leaves the esc with some overhead so you arent red-lining it constantly as such.
