So based one what I'm reading it looks like TTB is gone next year and TTC might be gone? The issue I see is running the math Most S2000's are going to have an AVG hp of around 205-210 range. Which puts them WELL short of what TT4 is going to hand them in terms of a power to weight. So the way I'm reading this is one of the most popular cars in one of the more popular classes is now going to be rendered obsolete due to lack of ability to make power easy enough to land in the class. I might be shooting myself in the foot by starting this thread as my car slides into TT4 nicely power to weight wise. But do we need to be arguing with greg for more allowances to give the S2000 a little help in the future TT4? Or do we request TTC stick around and just add 4 and slot the S2000 into TT5 in 2018?

The S doesn't fit into tt4 very well unless you have way above average HP and way lighter than normal. My car does not fit the bill. I need 30 more hp...

Brian, Im not even close. I'm at 11.4:1, Greg G will not let an aero S2000 get anywhere near the max for TTB which is 10.5:1.
I don't about murdering anything man, there will be some crazy built to rules TT4 cars coming out. There are a lot of modifiers that one can take advantage of such as FWD, 4door, etc. We'll see.

You MINUS .7 for non dot slicks, so for example if your raw ratio is 12.0, your new ratio is now 11.3 which means you're out of TT4 now.
You PLUS .7 for dot tires, so for example if your raw ratio is 12.0, your new ratio is now 12.7 which means you can either add more power or lose more weight.
This statement is assuming you're going to run a 245mm tire also.
*The penalty for running a non dot tire may have changed or will change though because there isn't many non dot slicks that are faster than a Hoosier A7 currently.

Yes, sorry thought it was -.7 and yes correct, tire width size will matter as well.
My TT4 setup as of now looks to be:
11.4 raw ratio
+.7 for DOT Hoosier A7 245mm
-.1 for being under 3000lb
Right at 12.0 adjusted.
It may change though but that is what it looks like for now.
