This is where you are showing that you are misunderstanding my intention. Both real world numbers ( correct data ) and proper physics engine are necessary. If you think Clio Cup with totally different spring rate and caster, much higher damper value than the real car uses is fine, then you never really care about accuracy of a simulation at all, all you care about is it feels great to drive and realistic enough for you.
Don't you feel curious how the Clio will drive if it has the correct spring rate ( stiffer front and softer rear ), correct caster ( lower ), correct damper values range ( the curve cover 20 click range adjustment and lower than Pcars renge ), and no rear anti roll bar ( yes the real Clio do not have rear anti roll bar, even the MK3 ). Then the correct final gear, Renault Sport uses special final not normally available from Sadev catalog ( Pcars sues finals from the Sadev Catalog, so one cannot know this without referring to the Renault Sport data )
My main issue though, is mainly concerned with road cars in PCars.
Have you read the consultant feedback report, they are based on custom tune not OEM setting for some road cars. Try drive the FQ400, that car has Nic Hamilton tune as stock, and SMS altered the steering ratio to be more forgiving as Nic likes very fast steering. The final FQ400 on release is basically Nic Hamilton tune, it doesn't not even use the real car spring rate. Nic didn't even notice the final gear is using 6 speed SST final, much lower at 4.062 on a 5 speed Manual Evo X that should have 4.687 final.
If you read the whole report, you will have greater understanding of what the physics lead and consultant did to each car. They often change the car parameter to what Ben Collins and Nic Hamilton think the car should do ( on a setup of their liking as they tweak SMS tune ), including specific tire of each car. The FQ400 for example, the spring rate was higher than the Eibach spring fitted on the real car ( if Pcars has proper spring physics and properly coded the motion ratio, this will make the car handle differently than it should have with OEM spring rate )
Then the caster, Oh my Lord, it has 6.00 stock caster as used by Nic, the real OEM Evo X caster is 4degree 25minutes or 4.4 degree( not adjustable/fixed ) Lowering can alter the caster usually 3.9 to 4.1, some stock Evo X has 4.2 or 4.1 caster ( degree ).The FQ400 is lower by 30mm front and 25mm rear from stock ( Eibach Pro Kit ). the ride height also seems to be off in Pcars. The higher caster alone alters the car turn in unlike the real car would drive. I havent touched the S-AWC yet, which seems to be not fully modeled ( ACD + AYC in particular )
See where I am getting at ... they are built with incorrect data to begin with, shaped to the consultant feedback. If the consultant didn't even know the car setup is unlike the real car, how they can be accountable for the end result ? They may give input to make the car drives realistic according to their experience driving similar car, like Nic said in his feedback on FQ400, he based it on his general AWD car knowledge ( he didn't mention specific real FQ400 handling traits ) and yet he also has to consider stable handling car as stock ( if you read in details ), Nic and Chris Ringley aim to tune the car to be good to drive ( stable, safe but still quick ) using custom setup.
My only wish is this, get the car data correct ( springs, tested real life weight/distribution, caster, alignment, gear ratio, and all the basic data ), then fine tune the other parameter like tire, chassis, aero drag etc using the consultant feedback. With old race car and data is scarce, I can understand, but the new cars like FQ400, 1M and Clio Cup 2014 Mk4, these should have correct data from the start of build process. This way, we can be sure Pcars is producing closer true to life replication of the real car and then when I get Pcars 2, I wont have to check the OEM stock setup and make correction again, just drive and be sure 100% it's as close as you can get to the real deal.
SMS also has hinted of giving OEM setup later on, will have to see if these OEM setup indeed correct OEM.
