Surely quite a simple one but would really help - more search filters when looking for tunes.
I suspect we all have our favourite tuners, clubmates and friends but otherwise there are far too many.
A good start would be a filter by tyre compound - yes it’s not exact given the use of drag, drift and rally tyres for road builds but a start. Equally drivetrain would really help, especially finding purist type builds.
I’m sure this is also mentioned in more general threads about car filters but that should also be filterable by tyre compound - the tyre graphic doesn’t differentiate between rally and off-road.
