Background

The info listed at Bonhams seems odd. Apparently this would be a 48 bhp Abarth 695 with a type 206 engine and a 5-speed gearbox giving it a top speed of 170 km/h.

When cross-checking these specs with bernimotori.com, which is the best Abarth source I have found on the internet, I found that according to Abarth the 206 engine produces 38 bhp (@5350 rpm), and that the 695 SS AC had a 4-speed gearbox that gave a top speed of 140 km/h:

Of course, that's "just" for a normal 695 SS AC, while the car at Bonhams is noted as a Competizione model, so perhaps it had some modifications done to the engine, and a special gearbox that the standard AC didn't get? I decided to give Bonhams the benefit of doubt and model my replica by the following specs:

Power: 48 BHP (Bonhams) @5300 rpm (Bernimotori)
Transmission: 5-speed (Bonhams, Bernimotori, Autmomobile-catalog)
Weight: 485 kg (Bernimotori)

I didn't find a single gearbox configuration that would give a top speed of 170 km/h, but by using the ABA 1652 5-speed gearbox and replacing its 5th gear with the 4th gear from the '68 695 SS the top speed does become 170 km/h. Of course, you still only have 48 bhp, so to achieve 170 you need to drive downhill or in the slipstream behind another car. Top speed on a level road and no slipstream is roughly 150 km/h.

Regarding the suspension and LSD settings, it's 100% guesswork and I picked settings that I think makes the car fun to drive. So you don't have to feel like you need to stick to my suspension settings. Use them if you like them, if not, feel free to adjust it :)

its ok buddy change my mind not gonna do it sorry for reply you abou it:)

Well, there might be other people having the same problem so I'll answer anyway:

When setting the gearbox and you don't get the values you need, you have to adjust the top speed slider. The values you need for this gearbox can be obtained by:

1. Set final gear to 3.700

2. Set max speed to 130 km/h

3. Set the gear ratios.
 
Here's an optional transmission setup for top speed:

Gear 1: 2.538
Gear 2: 1.474
Gear 3: 1.000
Gear 4: 0.741
Gear 5: 0.621
Final drive: 4.444

With these settings, the car will do 165 km/h on level road, and 178+ km/h downhill.

How to load the values:
  1. Set final drive to 3.500
  2. Set max speed to 240
