Signed up for:
Chin Motorsports track event at Road Atlanta: a TracQuest event. 2-Days: Saturday/Sunday on 05/04/2013.

Meantime, taking the car into CIN Motorsports for some light work:

- install CJ MS fuel starve kit
- figure out why my SRM isn't working (SRM light on)
- replace bracing on rear diff / chassis, and fix cross thread
- move SC oil canister lower on car

Others I will handle:
- get HDPro2 camera working with Traqmate
- fluids refresh and lab analysis on gear and engine oil

Question - what are the best SIM racers that have Road Atlanta? It's in iRACING, pretty sure... others?

We practiced on Forza. :P It actually did help a bit but the kerbs are much more forgiving in real life than they are in the game.

That is something I would like to know as well!

Thinking about my next NASA TT... I like the new rules! http://www.nasaproracing.com/rules/t...cation-sur.pdf

My car fits well in TT2... I could load weight ballast and go for TT3, but that would introduce a bunch of aero restrictions... I have to decide now between power and tire contact patch... here's the math - welcome any input!

I'll have to come and see you at the Chin event Saturday. I'll be at AMP Sunday.

wstar · 03-07-2013, 02:24 PM

Nevermind, had the points backward. I'd go square setup and better power, IMHO.

sig11 · 03-07-2013, 02:33 PM

Tire tire tire!

A friend last year ran TTB in his 350Z and did a lot of comparison testing at Mid-Ohio. He ended up deciding tire was everything. Ran most (all?) of the season on stock suspension, NISMO diff, a splitter and wing, and as wide a set of A6s as he had points for. He did a lot of testing from 245s up to the expensive extra wide 275 A6. He said the TT director couldn't believe how fast he was with that few mods at Nationals.

Hey Chris my next Chin event will be weekend of 4-May at RA... NASA TT on the 22/23rd of this month at VIR... would be great to see you at either!

Have to admit, I'm a grip fiend too! Inspires confidence... especially at VIR where more tire can help a lot through the esses

SPOHN · 03-07-2013, 04:25 PM

Ok. I'll be at RA Match 18 and AMP May 5. But I'll make it a point to stop by when your there.

wstar · 03-07-2013, 06:50 PM

Yeah maybe more tire is best, esp with your SC setup. I'm still NA and I always feel like my 295 rears are just "too much" tire half the time. I'm struggling to get 'em to push sometimes when I want 'em to.

My sentiment on this is completely reversing course now that I have better suspension. The problem wasn't too much tire, it was too much slack in the suspension of the car

Mike · 03-07-2013, 06:59 PM

295s work for me, but I run them up front too.

Sounds skinny to me. 315 front and 335 rear on car now. Going all solid bushings to hold everything in place.

I ran 315/345 for 2 years. It worked well on the hot days but on the cold days the tires never came up to temperature during the session. Out in always sunny California it probably isn't an issue.

So there is new rules this year so I'm doing an about face and running 275 square BFG R1 and/or Hoosier R6.
