* As I've (as a newbie) understood it the "default" wheel base on touring car chassies is 257mm. Correct? * The actual wheel base can be adjusted. This is normally used to tune the car for optimum performance on a given track under given circumstances. * I've noticed that different bodies have different nominal wheel bases that more often than not isn't 257mm. * For a good visual appearance I suppose the best option is to have the wheel base on the chassie to match that on the body. * When there's a clear difference in wheel base between body and chassie, like ~10mm, does it matter? Case in point: Protoform R9-R body. Optimised for technical tracks with tight corners (just as the one I'm running). Nominal wheel base 263mm, one of the longest I've found! For tight corners you're supposed to run a short(ish) wheel base. For my T4 chassie that would be ~254mm. The chassie has a maximum wheel base of 261mm, 2mm shorter than that of the body (and even more with some toe out counted for)! To me it's a little strange that Protoform design a body with such a long wheel base in the first place. More strange is that it's optimised for the type of tracks that benefit from a short wheel base. * Is the R9-R really a good choice for a tight and technical track, or is there a better option? * Should it be used with the wheel base maximised (to fit the body), or should the wheel base be adjusted for the track rather than for the body (ending up with the wheels very off relative to the body)? |

the simple answer is the body should be made to fit the car,otherwise your making setting changes which could be detrimental to the handling of the car,i always use a speed 6 to set up then change to say an ltcr shell and see how it changes the handling,the wheels cut outs are done with the wheels on the car using a compass cutter and i never follow the cut lines sometimes i have the shell sitting further forward on the car than the cutlines allow |

Thanks for the reply! Seems my impression was about correct. The nominal wheel base is a non issue. |
