Lancia Stratos
170HP La Festa Italiano Version
A classic of it's day. Iconic lines but legendary handling peculiarities
The brief for this build was quite an exciting one for us here at ETZ. The owner had a Stratos with a lot of miles on the clock and which had had some attention lavished on it in the past in terms of racing grade drive train and handling equipment.
He had always had a hankering to compete in the La Festa Italiano race series and to do so in a way that would garner the highest level of admiration from the crowd. Game note: The grid to be raced against was the first one that appears after a console reset.
Nearly all of the cars that ran in the series were 'modern era' and packed a fair punch in the Horsepower department, even tho' the FF drivetrain was the commonest seen in the field. However, the Integrale was an exception to this and our client wanted to be sure that this car could be beaten, even when starting from the back of the grid. As a fair number of horses had escaped from the old Stratos's engine, this added an extra layer of challenge to the project.
Tyre wear was not deemed to be an issue because of the shortness of the individual races (and because the car sat on soft compound 'serious' track day tyres already
). Aerodynamic modifications were ruled out for the simple reason that altho' the regulations of the series did not forbid them, none of the other cars would be using such.
Turn 2, Lap 1 and already showing what a tight line can achieve when at the right speed
As soon as we took the car out for a drive at ETZ's test circuit of choice (the Nurburgring) we knew that there were some quite vicious gremlins lurking under that '70's 'Wedge'. Coming to a stop sideways with your nose pointing at the inside of Aremburg whilst you had full opposite lock is not normally an auspicious sign
.
Our test drivers terse report concluded that the roll centres were out of balance, the weight distribution was not right for the length of the car, the camber change with damper stroke was wildly out between front and rear and asymetric fore and aft roll rates exacerbated all of the above. Oh and the brakes needed balancing too.
Not great then, we concluded
. He went off in a huff at that but we reckon he was just embarassed because we had him on film messing it up at the first hard braking from high speed corner on the circuit :angel:.
Let the boxy one cut the air for you whilst you bide your time waiting for a clean pass
After the first test run suggested we use harder compound tyres at the front to calm down the schizophrenic roll rates, the hardware we had to work with was as follows:
Sports Tyres (S2 Grade at the Front, S3 Grade at the Rear)
Brake Balance Controller
Racing Suspension
Fully Custom Gearbox
Triple-Plate Clutch & Racing Flywheel
Fully Custom Limited Slip Differential
That appears to be a Stratos sized hole you've left there "Mr. 147" - thank you very much
One thing we found as we worked at correcting the flaws in the cars handling was that the Stratos was more responsive than many vehicles we had worked on when it came to it's reactions to relatively small changes in the underpinnings. When we employed some lessons learned dealing with other unruly MR cars, we found that even changing the spring rates by an amount most other cars wouldn't even notice made quite a difference.
Opening the gap and pressing on to a comfortable victory
The settings suite we settled on is as laid out below. One thing to note is that if drivers wished it they could change the Final Drive to 4.110 at the Autumn Ring race. That effectively turns the box into a five speed and cuts down on gear changes.

There is more photography yet to be processed for the races at Cote d'Azur and Infineon Sports car but unless requested we don't want to overload the presentation with 'bandwidth unfriendly' visuals.
