Anybody run NASA TTC or TTB?

If so, what setup are you running and are you competitive within the class?

I ran a NASA TT event for the first time this month. Because of certain mods, mostly tire size, I had to run in TTB.


My car has:
4 wheel 14" stoptech BBK
Hotchkis sways
Quaife LSD
5Zigen FN01R-C in 18x9.5 et22 all around with NT01 275/35/18
TC Kline/T2 shock spring combo
SPL front arms, SPC rear arms

In it's current trim, I don't see the Z winning in TTB. I guess in different areas you'll have different cars, but at the event I went to it looked hard. I got third place on both days but the first place person was a good 4 seconds faster per hot lap.

Overall the car did better than I thought it would though so I'm happy. I'm sure a better driver could squeeze more time out of it, just not sure if 4-5 seconds.

It's competitive on TTC.

Forgot to mention that the car is far from ideally setup in the suspension department, so there's time to be had tere as well. It was the first time out with the setup and I didn't have time to tweak it much. I have a bunch of points to play with if I stay in TTB so that would help.

Yep, just got my TT license, but will have to move from TTC to TTB...SUX!

2006 350Z Grand Touring (Brembos) TTC +7
275-40-17 RA1 all around +5 ,a up 20MM over TTC base +4
After market springs +2 non-OEM springs +2 (hotchkis TVS)
After market sway bars +2 non-OEM Sway bars +2 (hotchkis TVS)
After market Front upper control arms (camber arms) +4 (SPL F & R arms)

everything else stock (shocks, engine, aero, interior)

So a total of 24 points

If I go to 255 tires, that takes me back to 20..but still must move too TTB..right? I would still need to make 1 more change....likely the springs since they are "street springs" with very little drop or spring rate change. and I have run successfully without them..and that would take me to 18 points and back in TTC...but changing springs is a PIA...and would not happen till the winter re-build period...

The darn camber arm deal is killing me...............

Yeah, if I were serious about a class, i could remove the adjustable arms F/R, slap the stock brakes back(06 brakes aren't too bad) and run 255's. That would leave me in TTC with some points to spare. My car is pretty low with those springs so I would still get about -2 camber up front with stock arms.

I'm not that serious about it though. Just want to see what times I can cut...

yepper, i will just run-what-I-got this year to focus on driving,,,make any changes to get back in TTC over the winter....

I plan on running TTC next summer. Looks like the greatest competition will be the Neon SRT-4's.

Jarred, when did u join Allspeed?

I won the TTC Championship in NASA's Rocky Mountain region last year with the following setup on my '03 350Z :

- Stoptech 13" fronts/OEM Brembo rears (Cobalt Friction Spec-VR pads in front, PFC 97 in back)

- 350Evo sways (set at medium front and rear)

- Koni shocks (rebound control set at 3/4 up from full soft in front, and 1/4 up from full soft in rear)

- Eibach Pro-Kit springs

- SPL control arms (2.7 degrees camber in front, all other alignment specs set within OEM range)

- Nitto NT-01 on OEM 17" wheels (tires were narrower than spec, so I got some points back here)

- JWT clutch/flywheel

The Z can be competitive in TTC, depending on who the competition is, and how often they show up. Also, you have to be good at working traffic, figuring out when to go for it and when to back off, and managing your car throughout the event (fuel levels, tire pressures and wear, etc.)

GaryM05

I hear you, but I think the extra camber you can get from them is worth the point cost (the Z really seems to respond well to negative camber.) If you really want to get down into TTC, I would recommend looking into narrower tires, though I understand that might mean narrower wheels, and much more expense to go along with it.

You would give up some cornering grip by doing that, but you would be right up at the top end of mod points, and I'll bet the car would be a little more fun to drive, since it will likely respond a little more quickly by not having to move around those wide r-comps every time you give the car some control input.

Don't you have too many adder points to run TTC?

GaryM05

Not by last year's rules, which is when I was running in TTC. I'm racing in 944-Spec this year, so I haven't looked at the Time Trial mod rules for 2008, to be honest, and of course it's possible that they've changed the mod rules/point structure since last year when I was running in TT.

GaryM05

OK, I've just spent a few minutes looking at the rules for this year, to see where I would end up in 2008 (it looks like the main difference from last year that would apply to my car is that they've slightly changed how they count tire points,) and here's how I would end up under the 2008 rules, since you've questioned my 'mod math' :

- Stoptech 13" fronts/OEM Brembo rears (Cobalt Friction Spec-VR pads in front, PFC 97 in back): +2 points

- 350Evo sways (set at medium front and rear): +2 points

- Koni shocks (rebound control set at 3/4 up from full soft in front, and 1/4 up from full soft in rear): +3 points

- Eibach Pro-Kit springs: +2 points

- SPL control arms (2.7 degrees camber in front, all other alignment specs set within OEM range) +4 points

- Nitto NT-01 on OEM 17" wheels (tires were narrower than spec, so I got some points back here): +7 for the compound, -1 for the size (245) = +6 points

- JWT clutch/flywheel: 0 points (this is a free modification)

So, 2+2+3+2+4+6 = 19 points. This is the most points you can have without moving up a class, which is part of the game. So, I'd still be in TTC this year. Again, the big difference for this year seems to be the tire classification, as I would have to take 2 more points this year than I did last year. But, I'd still be in TTC.

But you have to add +7 base points....at least for the Grand Touring....check out the base classification for the 350Z, and you will see an " * " that means add 7 points to base, if you see 2x **, that means 14 points....

This is the game changer...........


Nissan 350Z (287hp)('03-'05)(enth. ok) TTC 3188
Nissan 350Z (300hp)('06)(enth. ok) TTC 3339

What are your mods laze1? And yes the little astrick hurts when essentially all you got out of it was brakes and a lot more points to start with.

The way my car sits now, I would be in TTA.

I would have to ditch my UTEC or go down to 255's to get into TTB. Last year I was fine with a couple points to spare, but the 08 changes really added up.

How many points are big brake kits? less than 7?
