I tried searching, but didn't come up with anything. I greatly appreciate your response.

Ran Durango stuff for a yr. Time for change.

Would love to come back to CRCRC, but JCP in Indy has got our attention. Can't beat semi heated with indoor plumbing, catered food, and being closer helps too.Lol

Proline is the tire of choice for the fast guys. But I will try the bar codes

slow down, amigo! I was just inquiring. If they don't already work, then don't go rush out and burn a set of tires and wheels... It just seems that running two different tires front and back, with dramatically different compounds, tread design, and performance... would throw any setup for a loop.

If you already have a set of x-gear white springs, you could toss those up front... that would take away a tiny bit of steering. How are you running your electronics? what battery, and where is it sitting on the chassis?

Orion shorty. Looks like it's about the same place as yours. And I'm running a 9.5 motor. I have a set of bar codes, I just have not mounted them up yet. I do have the white springs I will try that too. I like lots of steering, but the way it is now I'm not consistent.

I have the alum hubs coming in the mail. Now I hear they run a larger bearing? Does somebody know the bearing sizes? Or part number?
Thanks

What car did you come from? When I first switched from the RB5 to the 6, I was flabbergasted by how much steering the car had... it was uncontrollable. But the more I drove it, the more I got used to it.. and now it doesn't seem to have as much as I perceived when I first started with it. It is a beast of a car!

(but honestly, it sound more like a tire issue to me, but I admit I know nothing of your track, surface, or tire selection options).

It is all your tires. I had same problem with AKA foam on our track. I would turn the wheel and just do doughnuts. Everything was fine when I went to softer foam and same tires.

I ran 3-4 packs with my aka foam, but never seemed like they got broke in. I put another pair in the washing machine a few times and that helped...

Scrubs MC work well with Suburbs MC at my track, but the Scrubs do need broken in before they feel right IMO. They can be too aggressive when new. I run my scrubs with open cell foams in the front aka reds in the rear burbs.

Also, make sure you don't have any toe out up front.

What I have been told, is that it should be back in stock anytime between 1-2 weeks all the way up to 6 weeks.
