Telemetry is now allowed in the ST rule book. That was something I wanted to play with, but couldn't do under PT rules.

We ran that combo at 2014 Runoffs Laguna Seca in our STL car, NB1 with B6. Gearing was spot on for that relatively slow track.

So is the consensus on the front aero that any small splitter is disallowed? I know that you get 4" in TT5, but if nothing's allowed in TT6 then why does the line, "functions as an airfoil ... and extends 2" or more past the outline of the immediate surrounding fascia is prohibited" even appear if all splitters are forbidden? I first read that as differentiating the larger TT5 splitter from a smaller TT6 one. It also seems odd to be allowing things molded in to "a replaced front fascia ... during the original manufacturing process" but not allowing the same piece to be built.

I read it as nothing is allowed except items called out in the previous section (cooling and whatnot) and appendix b. With the -1.0 modifier to rear aero the rules are clearly pushing zero aero. The iii section is calling out OEM front ends like the s2k CR, which was nerfed on the old rule set too.

I just don't see the logic behind this 18:1 proposal. How does this increase participation for 6? Not to mention the displacement rule which excludes SE30 and S944. ST6/TT6 is fucked with this rule-set.

The cost of SpecE46 is looking like less of an issue every day.

So the short story for me is;

my low powered TTE car that weights 2415 could lose weight pending my dyno results?

I dunno, doesn't seem TOO bad. I would have to add 30lbs of ballast to hit class limit, but that's after (mostly) optimizing for a class that's about to no longer exist. My ole BP05's meager 125whp would have been pretty perfect for running a little bit lighter setup. A heavy VVT 6 speed with mild power is probably going to wreck shop in this class though.

2460 / ~132avg (TTE* 136 peak) = 18.6
-.7 A-Arm = 17.9
-.3 Weight = 17.6
+.4 BTM Aero = 18

I think the 18:1 limit also puts to rest that thread of guys complaining about how their NC/FT86/RX8 street cars are too heavy / underpowered for TT5 and should be moved to TT6 because they don't want to remove their passenger seats or throw cams at their motor.

Except NCs are specifically banned from ST6.

cabowabo

That's my point. They have less of a leg to stand on now that the limit is 18:1 vs 17:1. Their argument at 17:1 was that they fit pretty damn well into TT6 and they weren't wrong. At 18:1 an NC would have to be bone stock I/H/E, so they could still fit without the exclusive ban, but it'd be a stretch.

There are 3 really loud folks who didn't want to change anything on their car go from E to 6. Everybody else now gets to go slower.

I actually like these three official changes:
The weight break for 226mm versus 257mm NSW will remain 2400 lbs.
The A-Arm Mod Factor assessment will remain at -0.7
100 TW Tire Mod Factor assessment will be increased to +0.5

Moving the class to 18:1 actually makes dyno reclass cars easier to fit into 6 without buying parts. Those reclasses were 18.5-17.5(for a 16.5 class). Now, they're potentially spot on pending some ballast here and there with no other changes.

Ahha, I misread.

Yeah I'm not quite understanding the logic behind that one.

I read those rules, but was too angered by the exclusion and going slower bit to digest them.





I'm with you guys on this. What.The.****?!

I've posted a reply on the NASA forum thread. I'd like to get as many people as possible to post on this thread with their feedback for ST6/TT6 for 2019.

From my perspective, I can suck it up on the higher ratio, but that displacement rule could really really hurt the class.
