Hi guys,
I am back working on my electric concept car virtually, I now have 1 month of free time, hence I have decided to get back to the project.
Two months ago, I messed around with different resins and styrofoam to use as plug and I got it right and I have even built few !:4 scale concept car models for few clients here, due to NDA I cannot show it here, but I will show the personal work I do in this form once I start working on it physically.

I now need to start planning the chassis.

The wheelbase I want to use is about 2550-2600 mm and the wheel track too I would like to add about 80mm to the heyen's roadster.
Is it possible to maintain the same suspension and add length and width to the chassis?
or
should I just make a chassis from scratch?
