Whoa, that's a lot of questions to answer
Of course, it was made on normal SLR and mod also goes there.
As you wished, check 1st post.
Just put the car on SLR and didn't do anything.
If you are asking about some other sounds, then answer sadly must be yes. On the first sounds I wasn't working to fix the transitions, I was just putting samples from Shift to TDU and I was uploading it. Now I'm putting much more heart into it, I'm fixing transitions, searching for other car with same revs if the car which I'm putting sound onto have only 5 samples (idle, mid and high) and supercharger whine also is better now, because transition of it is also fixed, as here in SLR. So the proper sounds, which I'm happy with, are: this one, MCL F1, Porsche CGT and GT-R R35. Veyron is also not bad, but supercharger isn't as good as here. Rest of them isn't so good. Maybe I'll redo them later, but I want to make all sounds from Shift atm.
