I'm the only B4.1 in 13.5 I believe, no one that is faster than me, everyone else who is runs a 22, rb6, dex or schui. I have a good friend who is AE sponsored, but he runs mod and we have been working on setup, he runs slightly different, especially with tires, he prefers the harder JC compound, but I find that having a 8.5 in your gives you on power steering based on torque, my 13.5 isn't as harsh, but when I tend to free up the rear, so far it has always been too much. I have like 10 small to med changes to try still, just don't have the time. I have been able to make the a every time, and won one night, but there are still racers who can pull .5ths consistently over my times. (yes just better driving is a big part of that).

My local track jumped the shark and went from a Clay indoor track to carpet. Does anybody have a good carpet set-up? I have the older B4.1 wc buggy. Also are there any must have upgrades to due to the B4.1 wc? Would Big Bore shocks be worth going to on carpet?

Im currently running a shaved U brace with C hubs. Our track is low-med bite, if I wanted to try A hubs could I just use spacers instead of putting a new Shaved u brace?

Thanks,
Rocky

BTW Anyone tried 4 1.3?

Yes you can. keep in mind that when the brace is shaved its a .060" difference which is a tad less then 2mm. i would start with 4mm and the long ball stud. You can break the u brace easier but if you just want to test with it its not really an issue.

stick with the C-hub as you need the traction , the A hub will have less grip ....

I find the C hubs to be completely horrible on loose tracks. The one thing it does not do on loose tracks is give me traction. Unless by traction you mean fishtailing everywhere.

Can somebody clear this up please? I thought the B4.2 came with Carbon C hubs but I see on the parts page its a Carbon A hub is that correct? And are most of you still running C hubs with big bores for indoor clay?

got my mocked up esc plate waiting for amain to deliver my b4.2

They come with A's. Our track is low to medium grip. I have used both A and C, and I prefer the A hubs myself.

Car squared up far better with 3 limiters. I run 1.6/green/27.5 ae oil. I can run more washers in the rear when running 3 limiters in the front. This adds infield traction. If I ran with 2 limiters, I found that I had to keep removing washers in the rear to gain ability to square up and exit a corner hard. Removing washers from the rear harmed infield traction. Because of this, I went back to 3 limiters in the front and more washers in the rear.

When I ran 2 limiters, I liked 0 or 1 washer with a shaved brace and a hubs the best. That is NUTS.

When I ran 3 limiters, I liked 2 washers on a shaved brace with the a hubs.

Even with zero washers in the rear, with 2 limiters in the front, the rear was still too willing to over-squat/roll coming out of a corner hard on power with lots of traction. Unfortunately, going up to the next stiffer spring, white, in my experience, at my track, makes the car suffer too much in other areas for consistency.

Makes me think 1.7s may be better in the rear with 35 oil.

Has anyone tried the exotek rear hubs? i got hooked up with a pair last night and was wondering if anyone has any feedback.

C-hub gives more grip & less roll , really good for smooth clay .

A hub performs best on bumpy , but has less grip . On really high traction or when using slicks A hubs are great ...

Not one better then the other , pick the one that fits your track conditions

you let us know, lol. A guy at the track was telling me he loved them, but then again he didnt even know they were A Hubs......grain of salt

this is just a suggestion but my car i bought from a local associated driver and the car is on rails. About the same med to high bit track, running blacks in the front and whites in the rear with 1.7 frt and back and 35 front 30 rear. shock in upper inner hole and outer hole on arm in frt. rear upper inner and inner on arm.

Theyre vertical ball stud so they could be whatever no? Btw, they're nice and keep the link away from rubbing the the springs
