I am looking into a 4-link Altered. Planning to use my current motor intially which should put the car in the high 7's. Eventually, I would like to go as quick as very high 6's/low 200's. Is there a big difference between the stability of the 125" and 150" chassis? I prefer the look of the 125" and there are more of them out there. Also, I figure a 125" would be easier to resell because of the compatibility with a FC body.
