Before the XRG facelift, there was a base model XR. Here is a lightly tuned XR on sporty 205/60R14's from the old days:
It didnt have the integrated rear spoiler, had a shorter wheelbase and front end, and a simpler suspension.
Then the LFSiA noticed that tuning companies were tracking the humble XR and decided to make a new series of 1.8L, 825kg racing based on inexpensive road cars. N2 didn't allow big spoilers or under trays and diffusers in the beginning. A maximum tire width of 500mm per side, 1.8L engine, and 825kg minimum weight (without driver) basically summed it up.
Tuning companies maximized everything they could in order to win, but the simple rules kept the racing close.
((Work in progress))
I want it to not be too fast or too slow. the old 1.8 has a narrow power band and a 4 speed dog box so you have to drive it hard. Also, don't hit the kerbs!
