Well after going through some of the tunes here,i decided to give the ol viper another shot,my ol acr was collecting dust and figured why not.I do a lot of testing on trial mountain and found that with this tune I picked up 1.5 sec. a lap,my best so far offline is a 1.22.063, I ran online also with tire wear on and got a 1.21.879. but killed the rear tires after 3 laps. I had to change my driving style some,be less aggressive entering corners,get straightend up and stand on it! I also had to run with TC set to 1 as its hard to be gentle with controller. To sum up my experience with the newly tuned viper,I think you just may see a bahama blue acr online for a little door to door racing.DragonthingRKM Motorsport's Python

Oh look, here's the RKM Python, a Dodge Viper ACR with a little more bite...
There is something I can't place my finger on here...whilst this car is not the first choice for proper racing, and whilst it doesn't really handle like a supercar should, it is still so amazing to drive it. And you will enjoy it until it bites you..q.which is your own fault
Just remember to be careful with that throttle...you might regret it otherwise

Er - so what your saying is that even though no aero figures appear in "settings" it does actually have downforce, but you only get to see this once you've added a spoiler from GT Auto...??

Yep which explains why some of those cars handle so much better than others in their class and why they have a higher base PP than you would expect for their power and weight.

Ok - cool... thanks.
Something else that Polyphony decided to do that totally doesn't make sense - if it physically has aero, how come it isn't shown in the same way as "non adjustable" aero - like the front aero that appears on a Cali (once you've added a rear spoiler).
Well confused now...

That's exactly what we're talking about with the ACR, once you add the wing you'll see it has 10 points of non adjustable downforce on the front.

Probably just a flaw in their GUI system. Seems only cars with adjustable aero have the downforce shown in the settings screen.

OK, cool cheers guys.
I hardly use aero for my cars, only time I really use it is when I'm running racecars, pretty much 9/10 (or more) of my road cars don't run it, so I never really noticed this. I mostly race road cars though, prefer the way they feel.
Hmmmm, that explains the Maclaren F1 '94 doesn't have a massive jump in PP when you add aero, as there's so much already there.
Understand now.. 👍

Does this mean that, in theory, the McLaren can have it's downforce reduced by installing GT Auto wing, then manually reducing it below the stock setting?
- 1,203
Nope , the car has a fixed downforce.If you add a wing , you add also 5 minimum downforce to the rear.You can´t go below.
Same as with the ACR.The car has 10/20 DF fixed and with a added wing 10/25 min.

Another name for this car is "Rolling Death". It's amazing that some mid engined cars handle like they are glued to the ground and will take any punishment you can dish out. While others will rip your face off and feed it to you.

WOW! I really wish PD had created one of these Civics as a Premium. At least a few more people would have "their car" in GT5.
Many thanks again to RKM for posting some great tunes for Used Cars!

Does RKM have a tune for the Neon SRT4? If not, are there any plans to make a tune? I have a good drag tune, but I have another sitting there ready to carve the corners.

A review of the RKM Cizeta V16 (looks like a road version of the Lamborghini Diablo with Ferrari Testarossa side strakes):
Sapphire's malevolent black swan is a handful. The RKM V16 is grippy unto itself at moderate speeds however it is easily overcome with the car's gobs of torque. My car underwent an engine overhaul (no engine upgrades) and with stock power, balance is easily upset with judicious amounts of throttle. This car badly needs a wing to keep the rear end planted firmly. For my tastes, the LSD needs higher settings to control the traction difference between the left- and right rear tires on exiting corners at high speeds.
Until that happens, throttling the gas will have to do.
Steering response is fast and the chassis balance is neutral, though with a HUGE preference for oversteer at the limit. Sure, the RKM V16 can hug tight corner apexes but the problem lies with exit speed. It's tempting to hammer the gas and power through the turn because of the improved handling and torque but that works against you. The V16 bites back with oversteer, though it's not difficult to rein in the back with opposite lock and throttle lift-off. I think the softly-sprung rear suspension contributes to the oversteer.
This is not to say that the car is not enjoyable or fun to drive. Not at all. However, the RKM V16 needs you to be alert behind the wheel because that rear end can (and will) slip with aggressive cornering. In my opinion, it'd make a real fun drift car but care must be exercised if you were to use this car to post quick times around a track.

Glad you found it as fun as it is supposed to be!
you are right about lap times, it doesn't do them unless you are alert and sideways the whole lap

Think I've got a track setup somewhere for max power and race softs. It's fast for a Neon but it still needs the "for a Neon" disclaimer.

Absolutely the best tune I have used for the ACR...great job! It settles into turns quite well as long as you set up the line correctly (all relative for the ACR) and dare I say it you can actually get on the throttle a bit early without losing it. Once it's pointed in a straight line it will run away from almost anything. Well done as I was ready to give up on running consistent laps with this car 👍
McLaren MP4 LM -
As I have a 8:45 am Constitutional Law class and it's currently 1:45 am I will keep this brief, for now. This is a car I haven't driven much to be honest, and I don't really know if I'm really driving it all that well. First lap around Spa with your tune (and a touch more power and the "B type" aero (same numbers)) yields a very respectable 2:29.884. Even more so since all the assists other than the ABS have been turned off. But then again is something that comes with every car nowadays really a assist? Different rant for a different thread at a different time. This time is also reflective of my standard controller configuration, yes this means the "analog" 'x' button is my go-juice activator as well as the "analog" 'square' button being by oh-****-slow-down applicator. If I ever got around to setting up my wheel properly and getting used to it I could see this time dipping a solid 20+ seconds easily.
Enough about the times though, how does this contraption feel on the track? In one word, amazing. It sticks just as you would expect it to and slingshots out of corners with the right amount of road-runner blood like a liberal to a 'occupy_____' rally protest! And the sounds it makes makes my willy all tingly. Trust me that is very distracting at 190mph on a curving straight! I colored mine the dark red from the dealer and stuck on some black rimjobs, all the better to emulate the scab peeling that this car inflicts on the competition, absolutely painful!
Oh yeah post #8000 in your thread! Do I get a sweet prize or something? Also I've been a long time user of your tunes, I also abuse them regularly as well. Good work all around.

It is a scary car before you get used to it's power and speed...and even then it is still insane! Good to know I am not the only one who enjoys driving it
I completely agree, it is a brutally fasr car, especially against similar cars. And don't worry about the extra power, I have a second more discrete MP4 with about 870bhpCainius

I don't plan to max out my track car (probably try to stay around 400-450 hp), but I would love the suspension settings. I don't usually use racing tires though, but I would like to try your setting on sport meduims, and maybe adjust some. I love the SRT4 IRL, and would like a respectable one in the game LOL.

I've never been online with it, so I haven't competed with anyone else. However, I am pretty sure that I have the suspension dialed in pretty good, comparing wheel spin to other I have seen. I might wreck it before I get to the straightaway, but it goes good in a straight line LOL. It is maxed out with 613 hp though.
