Wonder if AE is going to come out with new buggy springs like T5 and SC?

Looking at setups mostly see flat Pistons in shocks, not a lot of tapers??

As I understand, with 3 gear, less force is put on the front of the car during braking, more on acceleration - I could have this backwards.

thanks.
With the 3 gear you get a more reactive on/off power action no matter whether accel or decel.

4 gear is generally smoother/lazier part throttle; yet takes a bit more power to drive off. It will make the car drive flatter on/off power and harder to correct in the air.

Having driven both; I will never go back to 4 gear. You can adjust for the difference in weight very easily with pack location and C/D hangars.

Lite or CE kit? I run either a 8.5 or 9.5 motor with saddle packs... indoor medium traction clay, socal track/sdrc.

thanks.
CE kit since all the major tuning options are in the box and use a 7.5 or 8.5 motor.

Got a B5M FL and my rear hubs plays a hole lot and the rear arms to.
It feels like the plastic washers on the hinge pin is getting worn out.
Does anybody uses aluminium washers instead of plastics?
Iīve tried to search this thread but didnīt find any solution.

I'm thinking about building a second car specifically for turf tracks. I saw the red workshops lowrider setup, but it's rather pricey for me to do. Just curious, what are the other options out there? Or is that my best bet for this car?

Humpty just won the 17.5 class at the SDRC Topgun race and many other locals seem to be giving the "low rider" transmission a go locally. But like you said, pricey.

Has anyone else tried running a 34t pinion (B5m CE)? It seems the pinion is very slightly too big for the gear cover and is grinding against it. If I don't screw down the lower portion of the gear cover (which is where the pinion is) it seems fine, but that's not really ideal. I suppose I could grind off a bit of the inside gear cover if I have to but I didn't think a 34 pinion would be uncommon.

Drill a hole in the gear cover or if you aren't running on a loose dirt track, just get rid of it.

Check a few pages back. I'm working on one.
I'll post more info soon.

You can, or get a real thin shim and add it in. you can reshim to tighten up.

Don't love the 3D printing composite. Would be cool if AE came out with a kit or somebody like Jconcepts, MIP or Exotek.

What are you running for a spur gear?

Of those....I would think MIP maybe. Because they have already made one gear box and they have made chassis in the past, as the chassis will need new holes for the mounting. I dont love the 3d printing either. If AE released one, I would pick it up to try at srs for sure.

I run 34 and 35 on my B5M (original 4 gear). While it's possible they have altered the gear cover from 4 to 3 gear, it's unlikely that area would have been touched. Have you checked for a bent motor plate? Can you move the pinion down the shaft a little more? You could shim the cover out a smidge but unless you switch over to the fuel tube mounting method, the removal of the gear cover will get annoying.

we had an SRS local show up at our track in PA and told us that this was the first time he had to actually tune his B5M. At SRS it's all about just slam the car, dope your tires and put as much power into it as possible. You could run any setup and still wheel it fast. Hearing these stories always makes me chuckle
