Wheelbase adjustment BSR BT-4

Recommended Posts

I would like to fit a tamiya brat shell to my BSR BT-4 chassis which has been set up as a 4wd drift car.

 

The shell looks like it will fit fine if the wheelbase is adjusted to the two inner settings front and rear.

 

As the chassis is belt driven, do I need to replace the belt or is there a larger tensioner that I can fit to resolve the issue?

 

The shell is a hard body and a proper beater and is being used as a trial for a mint condition hard body shell to be used later on.

It is just the arms that are adjustable, I thought the wheel base was too but I was wrong.

 

I have moved the arms forward using spacers, it makes very little 2.5mm difference so I think I will cut and shut the arches to where I want them.
