Ofna/Hobao17mm big bores on a truggy
 

As of now i have Ofna 16mm big bores with Mbx6t springs on my E-Mbx5T and I'm not very happy with them. I started off with ofna gray springs (soft) and where far to soft, went with silver (Medium) and where still too soft and in a recent trade acquired some mugen springs and I'm now running 75/9.75 front and 86/10.5 rear.

I don't get to spend a lot of time at the track so a lot of my time is spent just lightly bashing around the yard trying to jump off misc things lol

So has anyone tried running Ofna/Hobao 17mm big bores on their truggy yet? If so what springs and oil? would these be a viable upgrade to the 16mm big bores? If i do switch over to something else I'd most likely put the 16's on my mbx5 buggy

I don't imagine that the 1mm difference from a 16mm shock would make all that much difference. I'm super happy with the 16mm big bore shocks I swapped out from the original 13mm bore shocks it was equipped with. The truck really needed a better shock to handle the extra weight and damping needs of the electric conversion. It gained nearly 2lbs from the conversion I think.

So your running these now on your jammin truggy conversion? I'd be interested in your spring and fluid setup. Maybe it can help me play with my setup a bit.

I'm actually running the Jammin big bore 16mm shocks, not the Hobao 17mm shocks.

As for fluid and piston hole size? I'm still experimenting. I ran the OEM size piston holes and 50wt fluid, it was okay, handled big jumps fine, but the suspension was a little stiff, and I still had problems bottoming out, there wasn't enough pack.

I switched to the smaller piston hole, and that pretty much fixed the pack issue, but the suspension was a little too rough so I stepped down to 35wt (I didn't have 40 or 45 at the time and the shop was out of those).

So still experimenting. 35wt was definitely too thin even with the smaller holes.

Yeah I was talking about the 16s. I haven't bought any 17s was just curious. I'm running the 16s on my mbx5t conversion. I'm running stock pistons, silver springs and 35w oil and they seem really soft still. I have to set the preload almost bottomed out to make the arms and cvds sit level. I guess I'll have to try the smaller pistons and some thicker oil

I'm using the associated front Bronze springs, and the AE rear brown springs.

They were alot harder than the blue ofna springs.

Bronze (fr)= 4.74lb/in
Brown (rr) = 4.09lb/in.

The truggy weighs in at 10.5lbs with twin 3S 5000mah batteries and a MMM/1515 setup.

Just read your ride height comment. If you have to use excessive preload to get bones level ride height then you need stronger springs. The Ofna blue 16mm springs are stronger than the silver ones you have now. The bronze AE springs I have are about the strongest 16mm springs out there I think.
