So much for being innocent.

Another great day of racing the USGT and USVTA cars at Rapid Competetion in GrandRapids,MI. The USGT car is fun to drive.
Looking forward to the USVTA NATS in FTWAYNE (Summit raceway) next weekend.

Hey y'all,
I've got a battery question... Right now I'm running 5000 mah 40c batteries (Gens Ace). I run these simply because it's what I had as they meet the battery limits of other classes I race or have raced in.
I noticed that the rules for USGT and VTA have no C limit for the batteries. My question is if it would really be all that noticeable to run, say, a 65c battery instead of my 40c? Would the improvement be substantial and, if so, in what way? I assume the difference would be in more punch out of the corners, but is that a correct assumption? Are there other benefits?
I like having a battery that's compatible with all the classes I race in, but if the performance jump is big enough with a higher C rating, I'll consider getting some.
Thanks!

Tommy, IMO based on my experience running good Thunder Power 5000 40c packs and new 6500 70c SMC batteries is that you will notice very little difference with a 21.5 in a USGT car. Notice I said "Good 40c" batteries. It seems the Gen Ace batteries perform good when new but don't age well with their performance dropping significantly rather quickly compared to some of the bigger named batteries. It is based on the chemistry used to make the battery that causes them to fall off performance wise and the internal resistance to go up.
It is a case where you do get what you pay for up to a point. You don't need to spend $120 on a good pack but you can do much better than a Gen Ace for racing IMO.

That's a good point that I was taking for granted. One of my batteries is going on 2 years old, but has been great. And I notice no difference between it and my newer battery. That being said, I have no idea if either of them is performing as advertised. I would be willing to pay for high quality batteries, but I've seen too many articles about the high end stuff not performing as promised, either. So what can you believe, y'know? 
That's why I just use the cheaper Gens Ace batteries.
That being said, I'm open to suggestions for battery manufacturers that are known to be as good as advertised and consistent.

Lipo packs in VTA & USGT Classes
I agree that if you have a good quality 5000 40c+ pack you will not notice much difference in these classes from that to a much higher quality pack.
I have done testing with my EA 5000 70c packs (These packs rock by the way) and ran back to back with my Revtech 6900 100c packs (Testing only!) Not racing in actual VTA & USGT Races and find no difference in performance or lap times.
Now looking on the other end of the spectrum, I have also tested 1 - 2 year old 5000 25c wolf packs that have a little less performance due to age. But we are talking about a tenth or two at best over the entire run. If you have packs that are over a year old you weld benefit just from a fresh one.
My thoughts are don't spend more than $60.00 to $80.00 bucks on a good pack such as a reedy wolf pack, EA 5000 70c pack, Trinity's 5000 Titanium packs are really good as well. Having a newer pack is better than having a really expensive one if it is quality and keep working on your setup and driveline.

Here's my TC6. The internals are still the same (Tekin RS Pro and Thunder Power 21.5), but it's got new shoes and....uh....new clothes?

Hey Tommy R, love that body! I work for SIEMENS, so if you need additional decals I might be able to find you some.
Here's one that I did for Crispy here in Indianapolis. He ran this at the USVTA Nats at Summit RC Raceway this past weekend. He's really happy with it.
A lot of guys run the HPI 350Z for USGT in this area. Good downforce and the front matches the round on many touring cars so well that it holds up really nicely.

BTW, regarding y'all's earlier discussion on using the number 69... When I was autocrossing my number was 16 and we ran in numerical order (lowest numbers first). I wanted to race later in our heat so I needed a higher number. A logical solution would be to go with the year I was born. Yep, you guessed it. 69. I couldn't let people think I'm "that guy" so I went with the year I (finally) graduated college....95.

Question ..
We run Jaco blues at our home track in the gt class.
Ran some hip xpattern d combound tires on 3mm offset wheels . Reset droop and ride height and car starts off great for about 3min then the rear end gets loose .
We r running 2deg camber F/R .
Is this normal to have it act this way or is the fronts over heating or what?
What would u recommend?

My xpattern d's do that. I tried the pro compound at the Us Nats at Summit, and they are way more consistent. I went back to the D's for the main and failed like a rock in the water. 
I also learned that you can run 26mm vta tires on all 4 corners. as gt rules state. "any treaded 26mm tires with any spoked rim" My buddy ran the 26m vta rubbers on all 4 corners and rocked the show in gt class. So i may try it.
