Recommended setting for DS3 user :
Steering sensitivity at +1 or +2, all aids off, except ABS 1 ( if not comfortable with ABS 0 ) with 4/4 brake balance as starting point.
Notes :
Lotus Evora has great track record in the GT4 class, the car was built in collaboration with Cosworth, who provide the powerplant, tuned to output 360PS. The car weighs 1200kg with 39/61 weight distribution. The MR layout provides excellent traction and good handling balance.
Suspension uses Eibach race springs and Ohlins TTX 4 way damper kit ( optional ), the base model comes with 2 way damper instead. I tuned the springs based on the real car motion ratio/whee rate, settled for 650 lb/in / 900 lb/in spring rate. I also made the damper stiffer as the car has considerable rake to mimic real life ride height setup. ARB, camber and toe are set to balance the springs and the stiff damper.
Gearing uses Xtrac 426 6 speed sequential with sintered dual plate clutch, so I fitted twin plate clutch and set the gearing using ratios from Xtrac 426 catalogue. The gearing provides good acceleration and top speed on the 3.286 final ( there are 2 final ratio option from Xtrac 426 that can be used ). A higher final 3.769 is used when the car is driven on the track with lower top speed required.
LSD in this replica is quite unique, I used 2 way setup with high initial + high locking rate, and it works well for the Evora GT4. This still allows for freedom when trail braking with the rear rotates nicely.
I tuned and tested the car mainly at Silverstone GP, aiming to replicate real life lap time. Target was 2:14-2:15s. During testing, the Evora managed 2:13s on 1.08 ( camber still broken ).
Please leave feedback as I haven't tested the car on 1.09 
UPDATE 1.09 : Credits to @cbarbosa, added another LSD setup with lower accel value at 27 for more manageable corner exit.
UPDATE 1.11 : Added additional suspension setup built for enhanced stability, credits to @danbojte for the rear spring rate test ( 15.18 ) and @ColinH96 for feedback on my tweak suggestions. This updated suspension offers easier handling and more refined on the edge behavior.
Tested at Silverstone GP, managed to beat the old time at 2:11.4xxx 
Crazy fast for 355HP/1200kg car. The Evora also tested at Nordschleife, handles okay there, should be great for 500PP racing.
UPDATE 1.11 V2 : Added additional suspension setup using no rake / equal ride height. This will add eagerness to rotate due to the reversed ride height effect bug.
I have tweaked the damper extension front and rear to accommodate the changes, as well as readjusted the ARB to control the body roll and the added rotation.
I also have added softer spring rate setup with higher ride height ( by 10mm ) for bumpy tracks like Bathurst and Nordschleife. The car will still need smooth steering, but the added freedom to rotate mid corner will help the car easier to negotiate tight corners. The added body roll will be helpful as cushion / early warning before traction is lost, it is also highly recommended to use the original LSD setup ( 20/48/48 ) to maintain optimum traction. Avoid curbs and grass is paramount 
ENJOY 
, I didn't look at custom wing in GT Auto. You can install it and have some downforce, not sure of the max value. I heard that on 1.11, some rear wing have max value changed. The Maserati MC GT4 at 390HP is not quick, it has slow acceleration and low top speed compared to other GT4 replicas. You can use Forza 4 power figure at 433HP if you wish, it will allow the Maserati to lap in 2:13s at Silverstone GP.
I have been asked to drive online by quite a few member ( tuning session, cruise and race ) , but I couldn't. I have issue with my internet, when downloading updates I always have xxxxx036 error ( server time out related ). Tried on my friend's house internet, same thing 
Having this garage is just my hobby that I would like to share, at first I was skeptical that anyone would be interested to cars made differently than mainstream tuners ( no outright speed or ease of use ) I also want to say that most of my replicas has high lock/initial LSD, to those who prefer LSD setup similar to other tuners ( close to open diff ) and a lot looser car especially on FF car, simply lower the initial and accel/brake, it will surprise you how much some cars can be loosen at the expense of traction.
I think I have about 30 to 40+cars on my garage that has yet to be posted 
I need to work on Wangan Midnight again too, it's been a while, just need a couple of cars, then complete the work list on real life section.
