Vote for SH tires, then 8-6 has enough power to break traction too.
Waiting what kind of ideas sinister gets from rulebook.

I'm liking SH as bread82 makes a strong case.

I like the stuff we have figured out, I was pre occupied with LeMans yesterday I have not gone over all the rules yet, I will tonight, should also build up the car to get an idea of how she be.

Jounijkk asked (remind me) about that fixed Miata, here it's, surely not totally fine, but better:
90/90
3.79/3.22
4/3
5/6
4/3
0.8/1.9
-0.02/0.00
Brakes 5/5
Ballast -4
Tires OZ Envy 4H +1"

Gonna drop nose bit to achieve better traction on front during last corner of Tsukuba, now I have to either make front tires scream or lift a bit throttle. Maybe getting front stick better after dropping it few mm, means small changes on springs and maybe bit other changes too.

Do a barrel roll!
Hello SiNiST3R

I have a question and that is, if we change tire width via GT6HE, does it make a difference in grip levels or in any type of way, or is it just for looks?

Tetsu *thumbs up*

It increases grip respectively. I have a tubbed out Noca with 405's and my Civette has skinnier front tired and fatter rear tires. Makes a big difference, maybe I'll throw some fatties on a Five-Dime to make a demo video when I got some free time, crazy busy last lil while.

You found any other than visual values for this on code, place where it counts tire width in physics model?

The car data counts in the physics. The Overall Diameter and Width both have an impact on performance, not just visual. The only value there that is only visual is the rim, we can put silly number n make the rims huge, but makes no difference, they will even visually clip the track if you go to big. Raising ride height can help a bit as ride height is fixed regardless of rim size, rim too big just go through the track, but act the same as normal sized rims.

Tires have size specs for performance OD/Width in the code. Then there is the visual code for the rims, but no performance related codes for various rims only a visual code. This is important to note we can completely remove the wheels by using a special rim code, and even then the car behaves the same, ride height, tire OD and Width all still in effect, but VISUALLY no rim or any rim makes no difference to me after much testing. One needs to understand when testing no 2 laps will ever be 100% identical.

The Bad shifting in GT5 and GT6 with the clutch, I hate it, basically you have to have your foot OFF the throttle completely and near fully depress the clutch to engage a shift. The shift wont occur if you have your foot on the throttle. Its basically rendered the clutch in GT6 useless, more effort than its worth...

I noticed few peeps complaining about this on many boards all pissed its not been fixed unable to comprehend why and often toss a few PD must be dumb jokes in there, asking always why it wasn't addressed in both GT5 and GT6. I have not seen anybody make the connection yet so I will...

Well it was actually done to fix a cheat being used online in GT5Prologue, yes this story starts with GT5P. What was happening is people with a clutch were flat shifting (shifting without lifting the throttle) but if your using a sequential shifter the throttle is blipped automatically (the grey bar goes red for the blip) so anybody with a clutch could drive the same car faster being able to flat shift with the clutch where DS3 and pedal sets with no clutch could not flat shift and ultimately were slower.

Check this video on youtube showing the flat shifting cheat



As you saw, full throttle on shift no blip (only can be done with the clutch) even hitting the paddle to shift no clutch will blip it , but no blip if you hit the clutch full throttle shift n dump.

In this next video we have somebody not using the clutch, could even be on DS3, so this is what the guys NOT cheating would see when shifting. You can see how much SLOWER a shift is when the throttle is completely let off vs a flat shift throttle on the floor..



And its pretty clear here the throttle gets blipped (reds) during shifts

Soooo PD re-coded the shifting so that IF you use a clutch you must blip the throttle fully as it is blipped for DS3 drivers and None clutch shifting. It makes things equal for ALL PLAYERS in the online format. I think it may take too much reworking how the shifting works to find a middle ground where shifting will be more realistic without jeopardizing the online fairness if it can even be done, since GT5P Gran Turismo has gone HEAVY in the OnLine direction, so online fairness in Seasonals, GTAcademy and even soon to come FIA events is a top priority for PD...

In the end shifting with the clutch is slower now then no clutch shifting. Perfect throttle blip on up shift equal for everybody and perfect heal toe downshifting every time.. Every set up with a clutch can be used sans clutch.

Then I'll have nice challenge on my mind, will challenge all readers here to do laps with few tunes, postings tunes and infos later here, many people will be surprised.
