I can do whatever I bloody hell want, thanks. :) Im not gonna change and down grade physics just so you can swap them all the time.

Reasons they crash your game is:
Cause I added a custom motor and have a custom name. TDUPE doesn't read new motor's.
So the physics want to read the custom name but you didn't install it on the SLK so when you tried the physics on something else its trying to find the "Honda S2000 1999" name in your database which isn't added due to you not installing the mod on the SLK.
The new motor is also trying to be read in your game though this gets added if you use the physics installer.
Kurgan I say again and again, make your own physics. Don't swap mine, there will be a time where I will keep doing this. You need to learn that I made the car replace the SLK and so I make everything (installers etc) be for that car. So if you wanna have the physics do them yourself for another car. OR? you could be a jolly good lad and use the SLK.
Complaining to me will not help cause I won't do anything about it, if anything I have a giggle at it. Cause to fix it from crashing is soo unbelievable easy that anyone can correct it. Think really hard and you can
succeed on fixing it.
(On a side note this isn't having a go at you, it seems the way I have to explain in a mean/rude term just so you can actually understand, its the only way ive figured so you can understand, all your posts never have anything good)
