To be fair, the car was built at b500 already, changed the build a fair bit, retuned and cut back around 12 seconds. I think it was in fort street race
Ah shoot, really ive spent a lot of time tuning the shelby already and it’s not that it’s not good, quite the opposite. It’s just I was looking for a challenge. I.e. tuning a new car or returning to an older car i hadnt extensively tuned already.
Maybe another car? Or the shelby daytona in s1? Or the shelby cobra 427?
I’m glad you guys are interested in the challenge! If we do it, I’m probably going to drive your tunes on a few different types of tracks to see if I can figure out how you’ve set things up. That’s kind of what I had in mind. Not really a timed challenge, although it would certainly be interesting to see how I do in your builds versus mine, so we can do that too, but I think mainly what I was thinking was just driving each other’s cars wherever we wanted and then trying to figure out the build.
I’ve spent tons of time with the Shelby Daytona already too. And it’s a fun car. I have an A and S1 if we decide to go that route. But my suggestion is the Mercedes A45 AMG Hatchback. It’s stock at B700 and we can upgrade it to A800. I drove that car on the very first day I got the game and haven’t touched it since. What do you think?
Yeah… Well i’ve tried tuning it a couple times. I know its a very challenging car to tune. I’m still willing to try.
The hatchbacks are some of the hardest cars to tune in this game.
Like Potbox I drove the AMG on Day 1 and haven’t touched it since. I think that would be a fun car to set up - and it maybe a different style than what I normally do based on my experience with some of the other hatchbacks.
Are we agreed that we’ll tune it to A800? Are there any drive-type restrictions - Stock, AWD, RWD? Any other restrictions?
And what is the circuit we should focus on when tuning?
I’ll see what I can do with this car to make it something I feel like driving and then I just hope you guys like it.
Oh joy circuits! The High Speed Circuit in Castelleto might be a good one for this car. But I really don’t know and really don’t have a preference so I’m up for anything.
As far as restrictions, I don’t remember much about this car other than I think it had a relatively high top end. My vote is no restrictions other than A800. After that, just make it go fast!
I should be able to have a tune posted by Saturday afternoon EST. I’m looking for to driving your machines!
High Speed in Castelletto is ok but as the name implies, it is rather high speed. It has a few turns that are more challenging the faster you go.
I am using the Promenade Street Race event to begin and may then also use Vitesse and High Speed Circuits to help with the car. Also, try the slalom in Nice to help with stability - run as fast as you can down the promenade and slalom between the light poles without hitting them. I typically slalom every two light poles.
I’m not quite sure how you want to do this, Since we’re guessing the tune, I’m posting the build so you know what I’ve put on so far and then you can guess the good stuff.
Here is my current build: [NOTE: Changes needed to be made, I added things and marked them with an *]
Depending on how this feels and how fast it is, I may change up the build and drop down to street tire compound and add some MOAR POWER!
EDIT: Yeah, it’s an AMG power is hardly ever lacking. Power and torque tend to be the cars downside but luckily this car isn’t that high up in the numbers game yet. It is a hatchback though so it definitely needs lots of TLC.
Here are some build tips.
Don’t use brakes, driveline, clutch or flywheel. Spend that pi on power or tyres.
Even if I remove all of those upgrades, I will not have enough PI to spring for the Rally Tire Compound. Therefore these upgrades all shave off weight. I could add more power but this car doesn’t really need more power it needs a better motor and the only engine swap puts in too high of a class. My thoughts anyways but of course I will give it a try and see what I can come up with.
Well, I couldn’t get a higher tire compound but I did remove the clutch and increased the front tyre width.
I do like the brake upgrade because I can change the brake pressure and on this car it helps with control considerably.
I’ve shared what I have so far if you guys want to try it. Perhaps it will be a good lesson in what not to do. 
The file is called joeB and the description reads “try me”.
I’m actually hoping that such noob wow pipes in on this thread and shares some insights. He has several incredible tunes and has spent a lot of time working on hatchbacks and fwd in this game. He predominantly tunes fwd cars and hatchback AWD conversions. He gave me some pointers on the differential but it doesn’t work out to my liking - though this may be due to the rest of the tune being so different. Since we are doing a hot hatch his input would be appreciated.
I always use brakes upgrades as it allows me to change pressure and brake balance. Also I race manual w/o clutch and sometimes the clutch upgrade helps to get faster shifts and only costs something like 1 pi. The flywheel and driveline i never use though. I’d rather spend on more power.
Really I hope so too, when Potbox mentionned the a45 i knew I would have a hard time with it. I was also hoping for tips from someone who really knows fwd or awd from fwd conversions. They really do handle differently from other cars in this game.
It is an occasion to learn something and i’ll take it as such. Really hoping we can crack this case or at least get an insight that would change our views on the subject.
I will on tuning this in a few minutes and keep you posted
Also, to go back on a sidenote in the thread earlier which may also effect builds. If you are physically capable then manual with clutch should always be used. It is the most beneficial upgrade in the game and costs 0pi. I am trying to find out where it was all broken down in an old thread but manual w/ clutch has always been highly beneficial in all forza games.
I cant remember the exact numbers or find the thread but i believe someone was saying it around .5 seconds per 1 minute. I would venture to see most tracks are approximately 1:30 to 2:00 long each so therefore .75 to 1 second improvement by adding 0 pi…
Not to mention this also allows you not to apply the clutch upgrade of 1-4 pi. for the same benefit. So realistically the manual clutch option is actually .5-1 second a lap upgrade for negative pi.
The only time manual with clutch wont give these benefits is if you are in a car with 1 gear!
I have shared mine as well, titled “joeb” for tge purpose of beign easy to find. Try me 2 in the description.
For the moment the best i could do around high speed circuit was 59.942, using manual w/o clutch
Now going to try ppi’s

Driveline is often a good upgrade. I almost always do it as my last upgrade as you can take off 10-15 lbs with 1 pi. i use it just to round out my pi. I would rather take 10-15 lbs out of the car than add 1-2 horsepower. Even so there are very few upgrades that only add 1-2 horsepower without adding weight nearly negating what the added horsepower has done. Also the reason i do it as a last upgrade is sometimes you can add the street or sport driveline even when at the top of the class and not increase pi at all. so you can lose another 3-7 lbs and not increase pi.
Ptg, you are right about the drive line. I do the same, but its not an upgrade i really consider unless there is no other choice for rounding the pi.
Lets say i have a race air filter and im standing at 598 pi, i would rather try to downgrade the air filter to street and fit in another street upgrade than imstalling a driveline at that point.
If all else fails i will put in the driveline.
About PPi’ tune, i gave it a 12 lap go around high speed circuit. I was aiming for 10 but i had a lap time of 1.00.054 and i felt i could bring it under 1.00.00 so i tried two more laps, without success. So my lap time with PPi’s tune stands at 1.00.054
Here are my impressions:
What i like:
-Sharp turn in response
-overall very responsive front end, at high and low speeds
-very stable over bumpy terrain and absorbs shocks very nicely
-good gearing
What i dont like:
-Rear end breaks loose very easily in turns, both under throttle and when hitting small bumps during cornering
-hard to correct course mid-corner as the car becomes nervous (perhaps because of lively front end)
Overall i really liked it but the car could really benifit from increased stability, specially in the turns and even in the small bends
Well, the good news is that we both like and dislike the same things on the car with one exception. I;m surprised you like the gearing - it’s stock, and I hate it.
I agree the car gets unsettled very easily and I am working on fixing that. To help, I’m downloading yours now to go drive it.
I’m not getting anywhere near your time yet on Highspeed but your car definitely has lots more power haha.
I’ve made some changes to mine Joe so I will be sharing the updated version in a bit if you want to try that - it’s a lot more manageable and should be able to catch yours timewise.
such noob wow said he’ll post here once he gets back into Forza.
EDIT: I caved and put on the darn rear aero - 
Well… The transmission does a fair job. Tbh i thought it could be better but i certainly didnt think it was stock.
Joetben15:
Pros:
Very stable under braking - back end stays in place
Very easy to feel the back end and catch it before it slides out
Stable over the off-road portions and during surface transitions
Turn well under throttle - good mid-corner behaviour
Stable when flying through the air
I like the gearing 
Cons:
High speed, off throttle turn-in response shows understeer
I don’t like the turn-in response
Easily unsettled with the smallest steering input under throttle coming out of the corner, however; this is easily remedied with the throttle so…
I’ve put in 10 laps with your so car so far and the best time is: 1:01.875. I’m losing the most time on the back two corners. It makes a good wall riding car
Driving both our cars this car needs a lot more inputs than I would normally use, especially with the front wheels just to keep it all together.
Can I have the back end of your car and join it with the front end of mine?
That would be ideal.
I agree my car needs more turn in but at this point i dont know how to without changing the tires
