I would actually fancy an all LX4 server at bronze level. Maybe alternating the server between LX4 and UFBR. Not between races but between days.
Swapping between races would mean a lot of people disconnecting because the other car may not be their cup of tea.
The LX4 would be a great build up to race 2.
The UFBR could be good practice for driving the restricted cars on sticky tyres at race 3.
It does not take a lot of talent to drive the UFBR safely but keeping the momentum in such an underpowered car is not something to underestimate. (something I still seem to lack
)
