If you are running mostly asphalt, you cant go wrong with the T4. All the belt cars seem to have the upper hand on the awesomatix on asphalt and its a wash on carpet.

Only thing you need is going to be the array of springs and a 1.3 front bar as well as a 1.2 bar.

Can anyone tell me durability level of the graphite arms compared to standard ones that come in the kit? I'm not the cleanest driver and didn't want to waist my money.

The durability of the graphite is really good. What surface are you running on? I recommend running the graphite on med-high bite carpet and the standard plastic on asphalt unless it is super high bite.

I run on medium to high bite carpet.

ok, graphite arms will work well then. I have never broken an arm, usually its something else that will break before hand.

I like a front diff with Gravity RC 2.5mil silicon in it. Has much better turn in from a spool, but still pulls you out of the corner hard.

Trouble is, it still won't pull as hard as a spool/rear diff combo, which cancels out the improved turn in.

IMHO this is traction level and power dependent. Front diff should be good from mid to high traction when having low motor power like 17.5T or higher. In mod its not useful really

I am racing 17.5 on very high grip asphalt and medium grip tight carpet. I found it fit my driving style better and that the increased turn in on asphalt led to better corner speed as the car doesn't under steer as much. With the spool I'd have to brake more to make the apex, so the corner speed just wasn't as good. On the tight carpet its night and day how much faster the front diff is. For me it was marginally faster on the large asphalt track, but had a much better feel and was easier to drive the car.

Thanks for the input on the front diff. I still have a associated tc6.2 with earplugs in the front diff and it works great that way. just wondering of options for T4 15'

It took me a while to be able to get to these:



Part no. RSD159

Made from 1.0mm CF

Also, I wanted to show you our new progressive springs. These are not the same as before, I fined tuned the rates to allow a wider tuning range.

I have been testing these on carpet, primarily the Golds F/R and I really like them. This is on high bite carpet. The corner speed seems to be up and the lap times have come down. The feel is really awesome as the car it feels so locked down and at the same time steering is increased.



RSD156 Is the part number.
