I just took Rotary's Atenza tune out for a spin...
wow.
A FWD sedan on sport tires has no business being this fast, or handling this neutrally. As a side note, I did use the '07 new from the dealer instead of hunting for an '03 on the used lot, but the tune works nearly perfect on it as well - with one little tweak. I'm assuming it's because of the extra 50kg or so of the newer model, but I had to back off on the front springs - to 11.5 - because the car felt a bit too jouncy up front over bumpy sections of track. Aside from that, wow... just wow. Great work, two thumbs up.

Funny guy.
I practically built the thing at the Ring; if that's not a rough track, what exactly is? I personally have absolutely zero problems getting it to stay planted at the rear under braking.
In fact, I just went back and tested a few different settings from start to T1 at the Ring... First was your previous set of tweaks (brakes, diff, camber), then my brakes, diff, and rear camber setup, then my front camber. Your set got ~40.250, stage 2 got ~40.150, my original setup got a 40.062. The settings you gave were okayish and very easy to drive but understeered slightly at high speeds, didn't tuck back in off throttle the way I prefer, nor did they allow as much rotation under braking. The halfway settings were better at low speeds than my original setup but maintained the understeer at high speed of yours. Downforce DOES affect the needed camber angles (increases the available grip, increases forces on tire, increases need for camber) and this should not be ignored.
Sorry if you think I can't take criticism... I can and I appreciate it, just not when it's a bash on my methods on a vehicle I know doesn't behave the way stated.
If someone is willing to send me one, sure. Got a few others that take priority as it is though.
EDIT:
I actually have a dedicated tune for the '07, I may release it eventually. The '01 Concept version ought to take the '03's settings more accurately than the '07 (as the concept is the correct chassis) and you win it from silver A-License.
But yeah, regarding it being excessively fast... I took it online a while back and got more than a few people to ragequit after they changed the tire limits multiple times to allow them more grip... And still lost on the corners.

Heh, I believe it. Seeing as you've done a couple Mazda's already, I was wondering if you were thinking of ever doing a tune for the MX-5? I've got a bit of a special interest in that car, since there's one sitting in my garage right now. I'd be interested to see what you'd come up with for it.

Roj has an NA effectively ready to go, I have an NC that still needs tweaking as it's a bit understeery.

To be exact, it's the J-Limited '91 that you can buy new or win from a license test. Oh and it's supercharged.
I'll be free tomorrow so I can post it then. 👍I plan on testing your rx7 tune soon as i get funds to mod it, i picked one up from the used dealership yesterday. I have two questions...
Will you be looking at a 07 WRX STI to tune? They are amazingly fast cars
i picked up a jj-r or something? Some car that with weight reduction i got to 620kg@305hp....i put it up in a online race with cars from up to 420hp...and i destroyed them, tho my tunes skills suck and the car isnt very good at cornering...you might want to look into this car as the ULTIMATE sleeper because of its power to weight ratio

Thank you you guys for the helpful information on tuning these various cars. Sadly I just saw this thread right after spending a large amount of money tuning my cars to the max. 
Is it okay if I can use these settings for my max tuned cars or I have to start all over from scratch?

Some of the cars work well fully tuned, others not so much. The Mazda6/Atenza, RX-7, Civic, S13 and Gallardo (save for the Gallardo's weight reduction) can all be returned to the specs outlined after having been fully tuned.
If you're going to review the car, do it properly with the correct specifications if you actually want something from us. If not, it's a case of use at your own risk.

It's funny how such a small tweak makes a big difference eh? Glad it's working for you. 👍
Purely for looks. I'm not sure if the Type B offers more or less downforce, but as long as the downforce value is the same, it shouldn't make any difference which you choose. I only specifically mention the exact parts I use at GT Auto because I figured if someone wanted to make the exact same car, it's easy to do so without worrying about which aero I used.
Also, your R34 is probably loose because it's got alot more power than the R34 I tuned the suspension settings with. So the way I intended the settings to work have probably been thrown out the window by the high horsepower increase.

Im not a big fan of muscle cars. I bought it and used it for the Amateur Series - Classic Muscle Car.
Before i do the upgrades (just trying to save credits) i test it out. Yeah it was slow, too much sliding when exiting corners, i hit walls on tight corners. i didnt finish 1 lap of Monza. So, i have to buy all the needed parts and tuned it as recommended by RJ.
And Wow..... it really amazed me, the power, the handling. Its all there. It slides at the back a bit, but doesnt matter.
Thanks RJ.

I tried the Spirit R settings on my DFGT and I found it wasn't all that fast around Trial Mountain. Can't remember my laptime as it was online. Something in the 1.30.xx. Anybody else have their laptimes on Trial Mountain using these settings?

Looking forward to it. 👍
I'll let you in on a little secret. Me and RJ aren't exactly fans of the R35. We are fully capable of making one, but we choose not to. However, we will tune one up for you on request, if you give us a detailed review of one of our currently released cars. 👍

If memory serves the Scuderia has more downforce available; the vanilla F430 will not even touch the Scuderia in terms of performance or handling capability, but it should still feel good with my Scud setup.
Yeah, it's definitely still a car designed in the late 60s and it shows in the handling. And the top speed. It's miles better than the GT350R in terms of grip though.
That sounds pretty damn accurate.
Mind telling me what car you have that's faster with the same PWR that isn't Roj's NSX-R?

Cant wait to check out the new rides! lol especially the EVO X 
keep up the good work guys.
keep up the good work guys.
Tried the NSX online on the ring today. Talk about total rape. Managed to out drive gallardos, GT500 machines and even a Citroen GT after sticked on his ass and made him over speed in to corners. Was amazingly fun. Need a awesome car like this to be able to get nice times in the agonizing night time. Eating lotus elises for breakfast, as well as Scuderias and what not. Just awesome all around.
The Rx-7 as well is damn fast, so is the R34 setups. Very easy to drive on the limit at all times, but none of them was even close to the nsx times. The RX-7 on a good run got about 7:25:xx while the R34 averaged around 7:29:xx. Easy to maintain high speed trough all sectors and handling is a dream. Can't really find any of the car tunes here with any flaws. So it gets pretty bland talking about them as it's mainly same words as they all really shine...

Hey RJ, I noticed something whilst reading your Scuderia tune... you've got the carbon propshaft upgrade listed, but this car doesn't have one; it's mid-engined. Nothing major, just being my nit-picky self, though I thought I'd point it out.
Oh yes, and the tune itself is working well with a preliminary drive, I'll try and review it deeper later on once I have more drive time in.
