Put in 2 more 8'' pneumatic tires in the center, drop them a 1/4'', and you'll be gold (for this configuration) Otherwise you are placing about 35lbs on each wheel (assuming you build about max weight) and these wheels are very grippy on carpet. With a wheel base that long, your drivers will be very unhappy.
We almost did something like that last year (our rookie year) but our mentor team helped us impliment a much better 8wd with the 2 center pair of wheels dropped about 1/8'' to 1/4'' (I would go 1/4'' using pneumatics, they squish alot more) And find time to test whatever you have on carpet before your regional!!!!
