A simple repaint of the Haas to change the black on the front and side to a more greyish colour.
EDIT: Also added a darker shade of grey
Open hass.erp (F1 2016\asset_groups\f1_2016_vehicle_package\teams\haas\wep) using Ego Erp Archiver
Texture -> Import select the haas_paint.tga
Save and overwrite hass.erp

For those wondering about the helmet I use a customised version of http://www.racedepartment.com/downloads/career-helmets-pack.11747
and the chrome effect is from http://www.racedepartment.com/threads/helmet-finishes.126474/
