Nothing personal taken. I never claimed I cared, only others care. Makes no difference to me. Whats-his-face entered the conversation like he was an authority on Ferrari's because his friend owns one. I pointed out that he wasn't an authority on the matter.
I don't even know what this applies to. Sorry for your confusion.
I love how you think a guy who *owns and drives* an actual 512TR is "not an expert". That just blows me away, man, Yeah, he's got money but he's also a
Tifosi of the first order (and a guy who worked his way up from nothing, btw) who knows every little detail of his car and risks the thing on-track at our private track every month:

While there are significant
on-paper differences between a 512TR and a Testarossa, they're nearly identical to
drive - especially since these cars (if used on track) are typically modded for reliability and added performance (and therefore don't drive exactly like an original car anyway). If you don't actually drive on track, you probably don't understand that even something as minor as changing tire type can really change a car's character - far more than a laundry list of factory tweaks.
You
will find owners of 512TR's that strongly feel otherwise, but I haven't spoken with them personally, and it's hard to find anyone who hasn't made a slew of reliability mods to their original Testarossa anyway. The point being: To keep an old, not especially valuable Ferrari (until recently - see below) like the Testarossa in running order, just about everyone modded the sht out of it. Values are now increasing, and most owners are returning their cars to stock and storing them.
Here's an excellent forum thread from actual owners of these cars:

And here's a fairly exhaustive list from a '92
Cavallino issue detailing all the differences. The car was simply improved over time, like nearly all cars.
Engine- Block is still flat 12 boxer engine cast in light alloy, crankshaft still has seven main bearings, the cylinders still have four valves and each cylinder banks still has two overhead cams.
1. Bore and stroke of 82mm by 78mm, 4942 cc capacity (unchanged);
2. HP increased from 380hp SAE to 421, with most of the increase coming from a redesign of the intake manifolds, a repositioning of the injectors, and a recalibration of the injectors, and a recalibration of the engine management system, the later controlling the integrated electronic fuel injection system;
3. Torque increased from 354lb ft to 360;
4. 0-60mph, 5.7 sec to 4.8;
5. Top speed- 180mph to 192;
6. New cylinder liner manufactured in aluminum with Nikasil coating;
7. New pistons due to larger intake valves;
8. Increase in compression ratio (10.1 to1)
9. Modified cylinder head gaskets due to a higher compression ratio and a different cylinder head coolant circulation layout;
10. Reinforced camshafts of a new profile;
11. Valve tappets with a new design bucket and springs;
12. New intake valves of a larger diameter;
13. Separate air boxes with filters, with a dynamic air intake;
14. Longer and straighter air intake manifolds;
15. Integrated electronic fuel injection system and ignition (Bosch Motronic 2.7) with self-diagnostic capabilities, and with ECU located in the cockpit;
16. Double independent submergible fuel pumps;
17. Exhaust manifolds with new layout;
18. Metallic type pre-catalyst converters;
19. Exhaust muffler with resonators and new heat shields;
20. Aluminum oil radiator with U circulation and without fan, allowing for better permeability; aluminum tubing;
21. Dual copper water radiators with U circulation in series and new aluminum tubing;
22. Coolant expansion tank located between intake manifolds;
23. More powerful alternator;
24. Secondary air pump with new air distribution pattern.
Chassis- Up front, the chassis frame was strengthened around specific points; for example, the steering rack mounts and the front suspension mounts. Highly stressed frame pieces are made of special chromium-molybdenum steel. At the rear, the old engine sub frame has been done away with. To gain a noticeable increase in stiffness, the rear frame was made an integral part of the entire chassis. The engine is now lifted out from above. Around the passenger compartment, the steel platform, rear bench, front and rear firewalls, and pillars are all welded directly to the tubes of the chassis. End result is that chassis flex has been reduced by 25% and torsional rigidity has been increased by 12.5%. Other chassis specifics as noted by Ferrari:
1. Weight reduction of 40kg/88lbs;
2. Lower center of gravity;
3. Reduction of unsprung weight;
4. Steering points in aluminum alloy;
5. New steering column shaft design;
6. New steering rack with longer arms and more direct ratios;
7. New steering moment offset;
8. Bilstein gas shock absorbers with aluminum body and adjustable plate;
9. New shock absorber settings;
10. Lighter weight springs.
Gearbox and Differential
1. Limited slip differential (40%) with reduced axial thrust to increase reliability;
2. New transfer gear ratio;
3. Strengthened transfer gears;
4. New synchronizer pre-loading springs;
5. Gear shift lever housing with sliding ball bearings;
6. New selector and modified gear shift lever inclination;
7. New single plate clutch with reduced inertia and asbestos free clutch linings;
8. Entire gearbox and transmission strengthened throughout.
Brakes
1. Larger front discs, 315mm x 32mm, with cross drilled braking surface;
2. Larger rear discs, 310 mm x 28mm, with cross drilled braking surface;
3. Aluminum calipers with larger pistons: front 44/40mm; rear: 40/36mm;
4. New ducts for brake cooling;
5. New brake proportioning valve;
6. Brake pedal ratio is more direct;
7. Redesigned hand brake with reduced application effort.
Wheels and Tires
1. Front wheels increased from 16 to 8 x 18 with 235/40 ZR 18 tires;
2. Rear wheels increased from 16 to 10.5 x 18 with 295/35 ZR 18 tires.
Styling Changes
1. New trapezoidal shaped air intake scoops on front with prancing horse;
2. Body colored front spoiler;
3. New profile to the C pillar fins in the rear sections with elimination of vents in sail panels;
4. Integral air intake slots added to the engine cover;
5. Rear lights are now dual colored and a redesign of the underbumper to change aesthetics of the exhaust system and exhaust outlets.
6. Wheels redesigned;
7. Interior restyled with elimination of center console and repositioning of the corresponding instruments under the central part of the dashboard.
8. Door panels and armrests have been changed.
Is that "authoritative" enough for you?
just have fun folks
Keep up the good work!
👍 Btw is this meant to fit on the Assetto Garage 2017 version (the new one) or is it meant for the older one on AC Car Mods Facebook page which has the two pairs of foglights?
