Actually not all 200 mm bodys will fit. 200 mm refers the the width of the body, but some bodys have different wheelbases. For example I have an hpi rs4 3 and protoform bodys don't fit my chassis, the wheelbase is different. But i have seen protoform ads in magazines advertising there bodys on the 4 tec chassis, so i guess that would mean hpi's bodys won't fit your car. I know the cadillac CTS V, and the corvette c6 body that protoform makes will fit because like i said they advertise them. I hope this helps a little, I found out the hard way that not all 200 mm bodys are the same. But i got some good money on ebay for it.
Is the 4-Tec nitro powered or electric? Most electric 1/10 touring cars require a 190mm lid where the nitro powered cars use 200mm.....................
just got a mail response from traxxas and they said that the 190mm body is a perfect fit, mine is electric, so maybe as nitro buzzard says nitro is 200mm..... i use my 4tec for drifting so i need it to be electric
