Main article updated with new testing scenarios 13-18 using the Sports flywheel and my conclusions based upon testing all available combinations on Race Softs.
The ultimate drivetrain for the Lotus Elise 111R is the Single Plate Clutch, with a Sports Flywheel, and Customizable Limited Slip Differential with an acceleration value of 50.
Lap times on new testing scenarios are with the same Test Spec car suspension and zeroed camber and toe settings as the first group; not from any of the discussions me and blueshift were having above.

Don't you think the sport clutch is heavier, so, it got more inertia so it also slow down slower (hence the slow shifting time : the clutch have to slow down rpm from the engine until it gets to the begining of next gear).
It's a shame we have no test tracks to measure braking power : I'm sure sports is better to brake too because it should have an effect on engine brake too (ie hidden bonus on "more decel"), but without having the DGL locking too fast with high decel (so you don't push while braking).
=> you have more torque at decel...
It's a great find, budious.

I think it's a shame what PD did to the RM version of this car, equipped with Semi-Race Flywheel and no way to down spec it. I had one in the garage but rarely used it until now, put it out on the track and noticed the same inconsistent lap times I had been getting during the tests with Semi-Race flywheel on the non-RM version. So I went with the high acceleration workaround with LSD, the combination of the extra aero downforce helps to keep it under wraps also, but combined the two help to make the car somewhat more manageable and drive like it's non-modded sibling. Now I'm running back to back laps with the RM all within 0.5s, before it was more like 2.0s on average cause of the random veering and snapping in it.

I play with a pad, basically I wouldn't feel like I'm really stick shifting unless I got a clutch pedal, like using a MT with paddle shifting. I get some cash put aside in a few months and GT5 gets patched up proper I get a wheel and pedals then let the fun begin. AT is more to eliminate driver error from the equation as far as tuning goes, occasionally I might use MT to race it when it's finished, but mostly not.
Ah ok I figured it must be for consitency since the shift points would always be the same(I assume). I was playing with the pad, and used the MT I liked it because it allows you to stretch out the gears which can come in handy. I bought a DFGT and its a world of difference! I have a G27 coming on the way then the DFGT will be returned lol. Look on craigslist for the DFGT you can snag it for $50 and it will exponentially increase your enjoyment in the game!
With the pad I always found throttle control difficult.

Last night I started running your 111R tune and it is very good. I am having a good time trying the different setups to get near your 1:12.500. I am hitting 1:13.200'2 consistantly and should get to your times soon. I look forward to trying your other tunes. Thanks Budius.

As i mentioned, my lotus has 303hp, the diff is set to 12 30 16. with sp clutch and standard fly wheel, the camber and toe all set at 0, with AT and duelshock i managed a 1:13.144 on deep forest.
Two questions:-
1. will lowering the brake balance smooth out the ferocity of the brakes allowing for quicker lap times or will it upset the suspension balance.
2. I can see the point when hot lapping but is the extra 16hp really worth the half a second, as when racing very few drivers consistantly lap the same time perfectly, mistakes, driving errors all happen.
great info by the way, you have soent a lot of time on this. much appreciated.

I imagine if you just purchased it you need to break in the engine for a while then change the oil to see the full 319HP. My lap times were pad and automatic shifting, your times may vary by input and driving skill, that's why I provided them only by the definition of a performance benchmark... you should see some similar time gain between your laps with the variable settings which were tested, whether or not you are seconds faster or slower than me on average. It's all relative and you can compare you own numbers and find the same gaps.

"but I'll be honest, it's no competition for any of the GT300 cars that have been run on dirty oil for two weeks to get them into the HP bracket."
Hey, Budious. Thanks for all of your hard work, bro. 👍 I find it VERY interesting. In your above quote, you implied that dirty oil is beneficial and I recall reading that somewhere else a while back. Can you please elaborate on this? Does it provide a fatter powerband or something?

Dirty oil is the process by which there are people who take cars that might otherwise be 340HP if they were properly maintained, and over the course of many thousands of miles, probably driven by Bob when they are doing other things, can drag the car down under 295HP... which if changing oil was completely realistic at all, then not changing it should result in sludge and destroying your engine! Fix this BS Kaz...
If the car was already capable of 295 if properly maintained, and you did the same, then you could fit more parts on it for peak power and torque at higher RPMs which gives you an advantage on the track. The 330-340HP GT300 cars already have very high RPM range engines so even at 295HP compared to an average street tune they have much more gear crunching potential.

I can see your point about "dirty oil" tomfoolery, but i can't see how this can be stopped. Unless the oil change is removed altogether, at what point will the engine become full of sludge and be destroyed and require a rebuild. This will always be exploited by someone which is a shame.

The patch coming out tomorrow will be reimplementing the Performance Points model used in GT5 Prologue. It's unclear whether this will affect seasonal events or is purely for online racing restrictions. The dirty oil thing could be addressed simply by making the car more symptomatic of engine failure when driving it, not necessarily actually having to destroy it literally. I'd just like for it to sputter and smoke and only go 50 MPH to stop the BS...

Thinking about this it could also be implamented via milage from the last oil change. most modern cars require a change around 10,000 miles on average. so a relative in game milage model could be made.
hopefully the performance points update will be across the board. Also a way to save more than one tune to a car would be most welcome.

I switch between so many cars... I don't even think I've worked on most of my Works in Progress... listed cars since I put them on the list... I have all new works in progress, attention deficit disorder ftw! 
I'm still tweaking on my methodology and process which is why I haven't posted more cars recently, I'll probably release a whole bunch at once when I figure out everything in fine detail and see where this new patch gets us on custom gearing. I been tuning my Camaro Z28 RM '69 for two weeks now and have over 3000 miles on it, still looking for that last 1% of performance I might squeeze out of it.

Hi Budious, the prospect of taking some vintage Italian metal (miraculously it isn't full of rust!) around some twisty forest roads was too good to pass up. So here's a
Lamborghini Countach LP400 '74 Review
Conducted using sixaxis controller on Region 4 PS3, update 1.06.
PARTS ONLY (default settings)
This car loves to yaw! Turn the wheel to oversteer, press the brake to oversteer, press the throttle to oversteer!! In braking, the rear gently slides out (which is quite controllable), but once on the throttle the rear has a mind of it's own. There's no wheelspin, just power oversteer; it's very twitchy and even more unpredictable.
Tyres are definitely a limiting factor, it would be much easier and faster with better rubber. Very difficult to tighten line mid-corner: your options are either lift-off oversteer or power oversteer! Deep Forest lap time 1:24.7.
Deep Forest Tunery Settings
Minimal changes to the settings (just removing the rear toe-in and loosening the diff), but they sure pay off! The basic handling character is still an Italian Drift Demon, but now the rear is far more predictable. Great stuff!! Kudos for not just bolting on the stickiest tyres you could find.
Lap time 1:23.4. The 1.3 second improvement is huge considering the small changes made to the setup. Absolute grip levels seem unchanged, I think the extra speed is purely because driver can confidently push it closer to the limit.

I only spec'd that car that way because it was originally for a seasonal time trial which was restricted on weight, HP, and Sport Medium tires only... and I did not spend all that much time on it. I've been meaning to go back and clean up the spec, but just haven't gotten around to it... thanks for the interest anyways.
However, given it's minimum spec, like you say, runs pretty good. I grind it on European Championship - Deep Forest for credits on occasion.
