thanks Bob. I did some digging around in the dedicated No Grip GTL Install and discovered...…
I had copied across the Game Data folder with all of the cars etc for the forthcoming series and all of the cars etc appeared to have been put in the correct place.
Upon deeper inspection, the Suzuki car folder was there and had all the relevant bits to make it work. Then I focused on the SOUNDS and uncovered the Suzuki folder, so it looked like I should have noise. But when I opened that folder it was empty
!!
Fortunately I still had the original Game Data download in my Downloads, so I opened that alongside the install and compared things. The same Suzuki sounds folder had a full compliment of subfiles/folders.
Rather strange as I had copied and pasted that very same Game Data folder into my No Grip install. At least it was simple fix, just copy and paste the missing bits into the Suzuki Sounds folder and that worked.
It did not make the Suzuki any faster, but at least it makes some noise now !!
