Porsche 930 Tuning Tips?

[YRS2703]

Hi all, I recently got myself a 930 Turbo that I decided to tune to the max, to replicate the Mid Night Racing Yoshida Special.
However, I noticed that as soon as I reach ~320kmh/200mph the car decides to spin out for absolutely no reason. Car was perfectly straight, no bumps on the road, and I wasn't applying any steering.
I don't want to throw on a widebody kit as that isn't accurate to the original car, yet I don't know what to do setup-wise so any help would be appreciated.
Full power and weight reduction, RS tyres. Around 570 bhp and 1100 kg IIRC.

Sounds like the ride height is too low. Also if you're running more front downforce than rear, that can cause weird issues too.

I'm going to try and raise the ride height a bit.. it does have a knack for oversteering on corner exits but that's just the nature of the car.
Could the dampers be an issue as well? Like the car hits a very minor bump and it just sends it spinning?

Have you tried Prianio's tune? Built for less power but will give you a good base

I'll give it a go tonight, but it seems like it was made with widebody in mind. I'd prefer to keep my car as a narrowbody as I'm waiting for another one to appear in the shop to convert to a widebody RWB Stella

Praiano's tune is great for this car. Personally, I feel all 911 racers should be wide-body, but to each their own (also, I doubt you'll notice if you don't widen it). No need to reinvent the wheel.

Wide body makes no difference to the physics, its purely cosmetic so won't effect the performance whether applied or not

Incorrect. You can literally see the stats that change on the installation screen. You can also run wider wheels with a slightly lower ride height without rubbing on the fenders.

Literally everything can be an issue on an old Porsche, especially one that's been maxed out.

You're best off posting your settings so people have more of a chance of steering you in the right direction.

I 👀 what you did there. Well-played sir!
