DIY-racetuning - The Ultimate Forza Motorsport 3 Tuning Resource

My times after 5 laps: Rd. America 2:11.043. Catalunya 1:53.306. Suzuka 2:07.688 Sebring 2:09.959.
These were all PBs for me, easily leaving the ghost of a grip tuned Nissan R34 in the rearview mirror. So obviously I love the tunes, can't believe you got so much grip out of the stock tires.
The thing that surprised me most was the diff. settings, thats the most aggressive setup I've ever seen. Looking at it I thought the car might shoot straight off the road accelerating out of turns but to my surprise it works great.
I also like track specific gears, this is something I have to try more in the future, I'm sure it's worth a few tenths a second a lap.
I look forward to seeing your walk-through and how you arrived at this tune.
Keep up the great work, it's much appreciated.

I think the road america tune is the tightest in the corners and tallest gearing setup of the bunch. It really is just about keeping your overall speed up while braking early and coming out of the corners fast as Tooner said.

And I think most are running the controller with clutch.

That. in fact, all of us are

We use the manual with clutch and a controller.

Using the automatic transmission is probably leaving you in the wrong gear around the corners.

When you say 12 seconds slower, 12 seconds slower than what car?

What are you times on Road America?

Those are some nice times, congrats. Glad you like the tunes.

You have to figure that since the R8 has a sticker price of $155k that out of the showroom the stock tires are probably pretty good

as for the diffs, the idea is to compensate for the lack of 'turn in' with a lot of acceleration on exit. AWD cars, even if the nose points in initially, tend to wash out in mid-corner, or past the apex.

The high rear diff pulls the back of the car around when on throttle. And the high front diff setting gives the front wheels more grip as you power through a corner. Add some rear toe-out and we get the car to rotate better. Slow speed corners aren't as much of an issue for AWD, but high speed turning is where AWD shows weakness. The diff-accel is all about the 'post apex' portion of the corner.

if you look at how the car performs in the carousel at Road America, you get a feel for what i'm talking about. At first the car might seem pushy until you get your timing down for when to lift off the throttle, if your timing is correct, when you re-apply the power, the back end of the car comes around as you exit the carousel.

Hi guys, Sorry if this is in the wrong place.


Where do you reccomend i start on a "Ring" tune for the R8? (other than taking all four builds out for several laps each)

Which one of your setup's should i try to work with first?

Me personally, if it was a build from scratch, i would usually put on races tyres, suspension, tranny and weight reduction, (basically nothing that adds weight) but no performance parts, then i'd take it out to see what it's like, but after reading and doing all 4 of your builds, my head's even more cabbeged!!!

Do i need F & R Aero for the ring? If i don't shall i put on slicks?

Think i've lost the plot now!!!! But it's all good fun!!!!


Your guidance is much appriciated.

Cheers

now theres a tough question, i guess the sebring tune will get you on around there quite solid, or try the road america if the gearing is more suited.

Personally never driven it on the ring, and more shocking havent driven the R8 in about 3 months... I just like RWD cars way more then AWD, love to work the car around instead of the AWD doing it for me.

Anyway, let me know how you get on.

Cheers Stig,

I'll give them a blast tonight and let you know tomorrow.

Must admit, i'm very partial to rwd too - can't beat blating out of a corner with your arse hanging out


On another note, I've not been on your store front (yet), but can you recommend an A600, that can beat/keep up with LP640's? (wanted something different to a AWD Viper, Ford GT..... hence i stumled on the R8!!)

I usually race with 6/7 of my mates, but one of the ******* keeps bringing it out, and i just cannot beat him!!!

Cracking web site and forum mate

Cheers again

Perhaps a 911 GT2 (997).

As far as the Ring, high downforce, somewhat soft suspension, decent tires (the car needs to be responsive).

Bah... racing with your mates and he pulls out a leaderboard car? might be time to change friends...

The LP640, S5, 03 Viper and the alfa 8c are pretty dominant in no limit A class... nothing you can do about it really.

Is it me or does anyone else get major satisfaction beating some of these LB cars?

Thanks to your help guys I have a MUCH better handle on tunes, using the R8 to learn from I have started to play with my Boxster '10 and can keep up with the S5's pretty well.

A long way of saying thanks, all I need to do now is add the DIY logo on my tunes.
