I like the durability of the spring steel plate, but what I didn't like was the consistancy. I run stock with all 3 screws in the t-plate with the medium and medium stiff ss bar and the car was more consistant lap after lap with the fiberglass. I could turn some faster laptimes with the medium-firm bar though.

What I also noticed is that I left a couple of spare ones in my glove box and they rusted. That made for an interesting look.

It's still up in the air, but I only broke 2 fiberglass t-plates this season so far and the ss plate is around $30. I raced at least 2-3 times a week and practiced 2 days a week so there was a lot of running on those plates.

What about carbon fiber? CF provides great dampening characteristics as fiberglass. I have some cf lying and will give it a try. Doesn't the CRC T-Fource have CF t-plates?

Thanks JD. Yeah the teflon is good stuff. The rear suspension moves much smoother added that I sanded the top plate with 2000 grit sandpaper. Don't go any lower than 2000.

Where did you purchase the Teflon tape?

Lowes or any hardware store for $1.00 and used double sided tape for adhesion.

revzalot, when you say you blueprinted the rear axle and plates, what does that mean exactly?

I've carefully sanded the axle plates a little wider where the bearings sits. This will reduce binding of the bearings. Metals expands during load. Before it was a pain to stick the bearings in the axle pates. I've noticed the axle spins much better now. Very good mod to do.

spring steel t-plates yes no maybe

is there any bennifit to having this option or should one stick with the fiberglass

thanks

I ran a Silva .071 spring steel T bar in my Yokomo/CRC/IRS hybrid out doors on asphalt all last summer with great results. I rarely had to adjust the tweak and when I did it was just to compensate for uneven tire wear. The problem with the fiberglass T bars is that even though you may not break one, they do begin to loose their memory. Meaning that a fiberglass T bar will not return to center due to the fibers in the fiberglass breaking which can sometimes be seen by a white mark where the T bar makes the transition from the chassis to the motor pod. Most often though there is no outward visible signs of degradation. So determining when to replace a fiberglass T bar becomes a guessing game. Before spring steel T bars came along, I was changing my fiberglass T bar about every 16 runs unless I took a very hard hit at which point I would change it then, even if it wasn't broken.

My only knock on spring steel T bars is that I wish I could get one thinner than .070 to soften up the rear of the car more. Even so, I will never run fiberglass T bars again.

CRC also makes the 2 pod discs (the 2 round black plastic pieces) in white teflon as well. Makes a damn smooth movement. Click on my sig pic of my old YRX-12 and you'll see it. The teflon circle sticker I used for my rear pod plate was made by some company, and it has little dimples on it, so the oil/grease can retain on the sticker/disc better. If you use just flat teflon tape, it works, but after awhile, all the oil/grease disappears.

ok one for and one agenst

i run carpet have you ran the ss on carpet and with the same success

thanks

No. Not yet as I run a Speed Merchant Rev.4 on carpet but... I am building a Trinity Reflex 12 and I will be running a spring steel T bar on it. My team mates keep telling me that for mod I should run a T bar car so I am building the Reflex 12 to test their theory. Although I am a bit skeptical of their reasons why a T bar car is superior to a link car in mod. But we will see.

I have played with teflon disk a lot lately. They are good to have in your box as a tuning tool. I came this conclusion as far as dampening.
Softest to hardest:
Stock disk with 100 wt. oil
Teflon disk with Trinity Red Stuff
Stock disk with Trinity Red Stuff

Of course everything in between with different oil and grease and different weight of springs, but those three combinations seem get me everything I need.
They didn't seem any smoother, just changes the dampening. I couldn't use oil with them though. My top plate has holes in it to retain oil, the teflon disk are to small and oil goes everywhere. They are a little smaller than stock. They are fine with grease though.
revzalot - if your using double sided tape to put the teflon on that adds some thickness, did you shorten the springs to keep the same spring rate?

take care

John: I found a really thin double sided tape by 3m. It shouldn't shorten the spring rates that much since I also sanded the top plate.

Crashby: Link cars were PREVIOUSLY outshone by T-bar cars in Mod, because link cars tend to be more "free" in the middle of the corner, in mod they would sometimes lose rear traction. Your Rev. 4 has been designed to address those issues, and I've watched them equal or better T-bar cars in Mod. At last years Carpet Nats, Jake Pritchard's car looked AMAZING, as did Brian Jucha's. I'm willing to bet that you'll like it every bit as much, if not more, than the Trinity car in Mod.

That t-plate is used on the six-pack and t-fource. It is nice and stiff so that the car is controlled by the springs, not the plate and springs. Both of those cars are spring/t-plate cars and you could go either way.

I agree that it works well for asphalt, just a little too soft for carpet. they are super stiff initially, but once they flex they seem to react too abruptly. I am not the only one who has said this about them. You dump the car into a corner and it fights it's way through because it wants to rebound too fast.

I actually bent two. I don't know how, but one incident happened right before Cleveland '03. I also bent one real bad before cleveland '04 and this was a medium-firm. I checked my new ones and 2 of them were bent a little right out of the package.

Suprisingly enough-in all my spectacular crashes last weekend Ian-I didnt even put a stress mark on my t-bar!!! I was simply amazed!!

so is the thickist t-bar from associated the way to go for carpet or is there a different manufacture you guys recomend. i just started with these and i need to stock up on parts
