Bobby, another thing to play with is foams. you can cut down a rear foam to be wider than a stock front to get a firmer tire. If you go from ribs to tapers outdoors it should make the front end feel less edgy and smoother, not necessarily more steering. Depends on the dirt.

What are you looking to get out of the change?

Trying to learn the differences between ribs and tapers mostly. Last time I ran 2wd offroad in the dirt we had ribs in H.T, Silver and Gold compounds!

I ran the Red ribs and Tapers back to back last week but couldn't get a good feel so I was looking for input on which one 'should' steer more.

With only two runs on the track with Red Tapers I would guess that the car changed directions faster but felt easier to drive overall. I'm going out to the track again tomorrow night and will try what you suggested on the ribs and wear them down a bit before I run again.

Thanks

I've got the Racers Edge rear hubs on my B4 and I'm snapping ball studs like crazy with em. I'm using the silver AE studs, should I be using the blacks instead?

If I land just a little off it's a guaranteed snap. The jumps aren't all that big and I'm not landing on my side but if I catch the rear first a little off it's game over. I'm use to balls popping off instead of snapping and having to break out the dremel to put a slot in the nub to unscrew it out. I replaced all the ball cups to get rid of slop but it's just caused more breakage.

Titanium balls? That's all I can think of right now.

Get a set of the titanium studs from lunsford. I got those on the sc10/t4 and sometimes b4. never had a problem.

Has anyone converted to using a gear diff instead of ball? Thoughts? I'm thinking of changing if it doesn't impact performance much. On the same note, what parts do I need to obtain?

It's been done and it's generally accepted that it doesn't work as well. Many SC10 drivers change their gear diffs out for ball diffs for this reason.

Titanium will break as well also if it doesn't break the hub bearings, bent CVD's, turnbuckle and rear brace. How about the b44 hubs? I run the old ones with titanium balls ends but there's new b44 hubs coming out. Are you running the Racers Edge hubs for the 1.5 degree rear toe in? This set up is used in very low traction only. I'm going to try the new AE t4.1 factory team Suspension mounts for 4, 3.5, 3, and 2.5 rear toe if it fits on my t4. Racers Edge are more prone to breaking the ball ends because of the top mounting position.

I thought about using the new B4.1 hubs as well. I did the extra 1 degree hubs since most run it now with the light setups and to run the larger bearing. I like the look of the new ones coming from AE so I'll get those when i can.

I've used Racers Edge .5 hubs for quite some time on my heavier SC10 with no issues. Lord knows I have test the strength of those ball studs and have never had a break. Prolly a dozen race days all together. Half of those on 1/8 scale tracks with huge parts killer jumps.

No maximum height really. But it will be hard to have a buggy that handles big jumps and that corners well at the same time.

The largest jump i have had my B4 on was a massive tabletop at The Tiltyard in VA years ago. It prolly got 10ft in the air and maybe cleared 20ft?

I had a friend that tailtapped on the launch and landed that jump wrong with his B4 and it snapped his chassis in two so that the transmission and motor and all folded over on top of the front end and got tangled up with the front shock tower.

Jumps are important. But i would start with something medium sized to learn how throttle and steering inputs affect the chassis mid air.

This is very subjective -- what about take-off angle. Just make sure that if a car gets a lot of air, it has a landing jump to down side, or else the fast line will be to bleed off speed on the face of the jump and barely take it.
