Installation instructions are in the zip.
Two hillclimb versions sequential and manual.
Two DTM versions 93 (no ABS) and 94 (ABS)
Two opponents cars : Alfa 155 and Mercedes 190 (simple aero for CPU).
Look at my profile page for Hillclimb tracks.
If you want sequential gear box on DTM : rename "data.acd" to "data1.acd" and "data sequential.acd" to "data.acd"
"Normal" (?) DTM version have H pattern, I think only 1996 ITC version have sequential. I have done a sequential (fictive) version of data.acd read the description and someone answer you in "Discussion" tab.
This car need improvement, I did not master very well the art of the aero at the time.
