Just reinstalled GTL after five years.I need some clarification about the Triumph 4 files.

Downloaded and installed Triumph TR4V1_1 from Altbierbude. From the Readme "sunalp2....To use this cars You will need to download the TR4 Version 2.0 package first, it's the new physics, from Butch at NFSBolide:".TR4V1-1 works fine without version2.0.
I even successfully added one of sunalp2's early addon cars the #17.

I have a mass of GTL stuff saved and it took me a few days to sort through it.I found two more TR4 files:
1)gtl-tr4a 33,013 KB downloaded 2009.The Readme file has no date or version number.
Is this the elusive version 2.0?
2)Triumph TR4V2.0 car files and biks by sunalp2.Includes the #17 car.Downloaded in
2007.
Just what do I have here?Is there a proper installation sequence?

If you are using the Autoupdater then you should have all the files with updates and new skins from me that you need for the Bude.

If you are not using the Autoupdater I really suggest that you try it as it saves a lot of time, effort and guess work.
