There's a lot going on with driveshafts that most people probably don't understand. I'd love to hear Cristian chime in, as I think he knows more than most.

The plunge of the driveshaft affects the suspension and drive line bind under power. A longer shaft plunges deeper, which makes the car more resistant to rolling under power which should translate into a "stiffer" front end. To me, it is sort of similar to arm sweep or moving the diff to a lower position. It basically keeps the car flatter through the corner.

Now, being honest, I can't tell much of a difference. I prefer our 51mm ones becUse of the narrower axle. Moving the coupling further out makes the car smoother as the angle it needs to turn is less extreme. This leads to longer durability and less re-builds, at the expense of having to replace the narrower bearings a little more often.

Can anyone comment on Paul's carpet setups for the t4'14, compared to the kit setup?

There's a trend from 2013 IIC -> Snowbirds -> Canadian Nats -> ROAR Nats towards a softer front end with less front end damping. I'm most interested in the ROAR Nats setup, because we use the same tires, and Kody came home and kicked our asses with his setup from that event.

But looking at it, it just doesn't make sense to me. It seems like it'd be really lazy and drag the chassis on the carpet everywhere.

What class are you running? Can you post links to the setups your referencing?

Mod TC on Carpet. Although I was considering trying it on my 2nd car (Stock TC) just for practice to see what it felt like.

IIC 2013:

Canadian Nats:

Maybe they're not worth trying at all. I don't have a Speed6 (only have LTC-R at the moment), and I only have 4* hubs. Everything else I have, though.

EDIT: My front diff is also 2.5M instead of 1M. :/

The thicker rear fluid slows the reaction of the rear end. It can help decrease a late traction roll. Yes Paul has been going to what some call a super soft setup. He has no worries about dragging the chassis.

OK, guys

I bought myself a second hand T4-14 and I am trying to remove the centre spur gear, by loosening the orange gear holders, one needs to be removed from under the car,

this is were I get into trouble as it will not loosen, the screws are so tight that I broke one..(Now needs to come out by drilling it).. !? I am using 2mm hex Hudy tool so it shold be a good tool..

Heat the screw up with the tip of a soldering iron. Generally the aluminum will expand more than the steel and it'll soften any loctite that may have been used.

Beauty thanks guys. My local track is a dealer for yokomo. I'll grab one to try. I do like the look of the white low friction belts. Might try and get a set of them over the next couple races.
