Will this be enough?

I have the Truerc 8000's and they seem ok so far (only used them for about 30 minutes) and especially for the price.
They are only rated at 10c though so using then in 1p configuration (4000mah) might be a bit much for them in a 1/8 car. They are also a bit longer and wider than the maxamps and won't fit in most battery trays, but I think they aren't quite as high, just something consider when planning the lay out.
Oh, and I think they make 6400mah packs which have a bit smaller foot print.
