    This one fell down the rabbit hole! Time to bring it back to the front and get some more tunes for this gem.

    I am currently working on AutoDelta Alfa Romeo Giulia 1600 GTA Corsa, with Furiani racing spec engine 170 to 180+HP. I am pleased with the test result so far, 1:08s at Tsukuba on comfort soft with 170HP, and stock weight + stock gearbox. Should be fun to drive :D

    Lots of interest but it looks like nobody had time this month. :( Of course, feel free to add any tunes to this or any other past thread if you have one.

    On to next month. Looks like Euro supercars 90-present. Doesn't really narrow down much does it? :lol: I'll toss out two having looked over the database that @XS maintains: Spyker C8, for which there is literally no entry to select, and the redheaded stepchild among the RUFs, the CTR2.

    Notes :
    Inspired by classic historical touring car and rally car from 60's, I made this special build, not a replica, but rather a tune with replica theme :)

    I based this tune on a real car that has Furiani built racing engine at 184HP that was installed on a very rare race spec Autodelta built Alfa Romeo 1600 GTA ( there were only around 40 built ). The real car has roll cage, 5 speed close ratio gearbox, custom suspension and dry weight at 740kg.

    For suspension, I used real life approach in tuning, 1600 GTA has a high rear roll center, while the front has low roll center, even more so when the car is lowered, this produces steep roll axes. This is the main reason the car needs to run very stiff front springs and very soft rear in real life, the same applies in GT6 :D. This also creates another problem which requires good damper and ARB tuning to balance things out. I settled for 9k/4.28k springs with damper tuned to even the load, and ARB to stabilize the car on entry and mid corners.

    LSD is based on 2 way competition spec ZF LSD with larger friction plates, and 4 lock position at 25%, 35%, 50%, and 70%. For this build, I chose 35% lock with optimized initial torque for balance on all tire grades from comfort/street to racing/slick tire.

    Gearing is based on racing spec close gear set, with a host of factory final gear options from Alfa Romeo ranging from 3.728 to 5.860. The stock final 4.555 is used on this build.

    I tuned and tested on a variety of tracks, from Autumn Ring Mini, Tsukuba, Silverstone Stowe, Fuji Speedway F, and Brands Hatch GP.
    When tested at Tsukuba, it managed 1:08s on comfort soft, and at Autumn Ring Mini 45s on comfort soft :eek:.
    The car has a a lively rear on mid corner to exit, easily controlled with throttle. This gives the driver so much fun and enjoyment on all tires from comfort to racing tires. With racing hard, it's capable of easily post sub 2 minutes at Fuji Speedway F.

    The Alfa is a BLAST to tune! I'm surprised more people haven't had a go with it! I will post my tune as soon as I'm done making a nice picture to go with it.

    Transmission
    I tried to use Praiano's transmission tuning method, but it failed to produce any faster lap times and I didn't like the way the car felt as opposed to stock. So, imo, leave this stock and adjust the final gear to each track.

    Limited Slip Differential
