A Bike engined car will be a lot lighter so each wheel will have less weight acting on it to get things spotty dog ideally you need to know the weight of the finished car....Then it comes down to weight of driver/passenger etc.
Imagine a car corner weighted as it sits then some one as big a bloke as Lesg sits in the drivers seat...said car will be all to wonky so it needs corner weighting with the big fella sat in the drivers seat to get things all tickety boo so he can wazz about safely.


I'm not saying les is huge but his arms are bigger than my legs....
