Opera Performance S2000 '04 - Built for MCH's FITT Race Car Tuner Challenge
Be warned, this car will not drive like the competition, it has next to no downforce compared to the proper race cars, but don't think that means it lacks grip. It can be a little fragile on the entry to corners that drop away, T10 (Bruxelles), T13 & T15 (either side of Campus), it is much more stable into the flatter or uphill corners. Through Eau Rouge it is possible to carry 130mph+, but requires absolute commitment from the driver. The faster drivers may be able to negotiate this section and the tricky T18 jink by merely lifting. For drivers like me a dab on the brakes is required, but keep your foot firmly placed on the throttle.
There should be nothing else for drivers to fear from this car, it has amazing pace. If you nail Eau Rouge just right, you should see 156mph before T7 (Les Combes), nearly 10mph faster than any other car I've tested. The aforementioned drivers may see higher speeds than this, the gearbox will run on to at least 166mph. Not that I'm expecting to see anyone get close to that without draft.
Use the pedals to modulate your line through the corners, you won't have the assurance of the downforce that the other cars have. Tiny, tiny modulations of the throttle will see you safely through most things. It's better to lift by the smallest fraction than to run wide and risk the car being upset over bumpier curbs.
Final note, I had difficulty testing this car at Spa, as I'm too tight to buy the DLC. I had to use the Dreams Cars Seasonal event, which presented its own problems. I have run the car at a few other tracks, in a private lobby and it seems to be ok. In all honesty, I don't know how well it is going to run in practise mode
