if you wanted to open up a little more space you could move your receiver to where i did on my tc4 on the front bumper. you battery is set a little high which will affect the center of gravity a bit just watch you high speed turns or the car will roll. you could try to mount the battery on the side between the wheels would help the COG with the battery monted on it side the body should clear it just find. if you got you a stale pack you would have a little easy time fitting it in the car
