I'm really doubt you will find any place that sells that part seperatly. You will probably have to contact IRS, or just tape your batteries down.

that was my wort fear. anybody else have any ideas i don't want to tape my batts.

see if some aftermarket battery posts will do. I know there are some for the yokomo sd and other cars. Taping isn't a bad thing, i prefer it over battery posts.

I have had no problems with the TC3 going fast on asphalt. I personally have never raced on carpet before, so I do not know how fast my car can go on carpet, but my car is fast on asphalt.

The TC3 is fast on any surface. I didin't run carpet for 6 years and put a suggested setup on my TC3 I was given by a friend that was running carpet and it was like I never missed running on carpet. Car was hooked and fast right from the beginning. The TC3 is a very versitale car.

Speaking of the IRS TC3; I don't see many people discussing it. But I know that a lot of people have them. Does it perform so well that no discussion is required?

We have a couple people at our track that run them. I think that the newer aftermarket chassis from BMI and Warpspeed are better designes. I know my BMI has the batteries much closer to the center then the IRS, as well as being a stiffer setup. (And the irs DOES have the extra supports around the outside). I wouldn't be suprised if IRS changes there milling to get the batts closer to the shaft since all the new chassis are that way and there seems to be a lot of people milling the tub chassis to do the same thing.

The reason no one is talking about the IRS chassis is because its useless as a race chassis. My tub chassis has less flex than one of those things. IMO just a piece of junk. Surprising tho as IRS makes excellent products otherwise.

I used to run an IRS chassis. I may have what you're looking for but it's been awhile since I've looked at it and am not exactly sure what part you're missing. Can you post a picture of your chassis so I can see what you're referring too

I do not see any reason why taping the batteries would not work. I tape the batteries down in both of my sedans that I currently drive right now(thinking of taping batteries in B4 as well), and I have had no battery fall out of my car. As long as you tape the battery in the car correctly, it should not go anywhere... (it should accually be an advantage, because when you have to add weight to your car to make it legal, you can put the weight under the steering rack or something in the center... )

I run the IRS chassis. My friend has the warpspeed and my IRS seemed to handle better.We had similiar setups(different electronincs). I think its because the Warpspeed is designed for carpet, therefore will handle better on carpet than on asphalt

Call IRS. They will sell you whatever you need directly.

Do you run the chassis stiffeners?

DZBMF

jmeadowz, no i do not run the chassis stiffeners. I just have the graphite chassis and the standoffs.
