Hey everyone,
I want to get more into tuning and therefore need a proper test track for my tunes. It should be a balanced one because I would like to use my tunes for online races where I need good all around cars. I usually drive in S1 class. I would be happy to get some recommendations 
I use Horizon Mexico Circuit for tarmac testing and River Scramble for dirt testing. Both are (I think) the best average circuits with all sorts of corners or challenges
I tuned my 98 supra on HMC, but its very flat and once I took it “to the real world” where there are some undulations and what not, my supra did not like it lol.
Okay thanks, I will give it a try
I’ve started using Tierra Prospera Circuit for my test track. Among other things it’s good for tuning camber because those long sweepers give you a little time to study the telemetry. Playa Azul’s also good but it’s missing tighter turns.
I do all my testing in the ocean. I’ve never won a race.
Joking aside I also use the same tracks as MastR74. I’ll also sometimes just pick a spot on the map that’s really far away but generally I only do that for small tweaks to over/understeer.
For off-road (like trucks & SUVs for cross country) I actually do use the beach quite a bit because of the deep sand and compacted sand. There is also a track but I can’t remember it’s name off the top of my head. It’s on the left side of the map…
