That's good to know (about the shocks). I've always felt that Mugen's shocks was the one major shortcoming on an otherwise excellent car. I am thinking of putting TTR shocks on my car for this season. They are hard anodized and inexpensive. They also have the right size bore (pistons the same size)so setup should not change much.

David,

I hear the Mayhem shocks are even better and cheaper. I'm picking up a set to try on the MSR. They are hard coated and supposed to work just as good as the JLB shocks but only 1/3 the price

Check out the TTR shocks on Amainhobbies.com. Less than $60 for the set.

Hi Dave,

I checked out the TTR shocks but I'm not fond of the shaft diameter being reduced from 3.5mm to 3mm where the rod end screws on to. The SportWerks shafts are 3.5mm and so are the threads for the rod end. They are also $58 for both the F&R complete sets, come with springs, preload clips and are fully assembled.

I think the mugen shocks work great and very easy to adjust.
Smooth as glass!!

The Mugen shocks are great. Never broke or bent a shaft. But after one race day the oil is all gray from the psiton wearing the aluminum bore inside.

Black pistons are 2x 1.5mm hole. White pistons are 2x 1.4mm hole or there is another option pisotn that is 1 x 1.9mm hole. Interestingly enough, the black pistons (1.5mm) come stock with all MBX5 and Prospec kits. Mugen replacement shock kits come with the white 2x1.4mm pistons. Strange?

the 1.4mm piston will give more "pack" or high speed damping.

Things that make you go hmmmmmmmmm.

1:The good thing is Mugen shock are easy and fast to change the shock oil out.

2:I thought the replacement shocks are not in the USA yet?

3:The 1 piston and 2 piston confuse me.
Why not change the bore of a 2 piston? Its just too deep for me.
I guess I willl have to reread my XXX Main setup book again. Not that it tells anything about piston #

What he is saying is that the black pistons have 2 holes that are 1.5 mm in diameter each, the white pistons have 2 holes that are 1.4 mm in diameter, then the optional pistons have just one hole that is 1.9 mm in diameter.

So how does the 1 hole compress compared to a 2 hole piston. The 1 hole is larger by .4mm. I would guess the 1 hole would have less compression then the 1.5mm.

I am not sure how that works out. I have seen a setup that Chad Bradley used the 1 hole piston but I can only guess that it causes even more pack? I've never tried it. I find that the 1.5 piston and 350rear and 400 front works very well everywhere so I must admit that I have not experimented much.

Default conversion mbx5 to prospec

I am just getting back into racing for this summer and I have an older mbx5. I was wondering what all the upgrades are for the prospec and can it be converted easily. Car has maybe 2 races on it and is still like new so I do not want to buy a whole new car, but would like the upgrades that most affect the handling, especially the steering. I heard there were new a-arms and uprights, is this correct? Will they fit the older model? Thanks for any responses.

The only Prospec upgrades that directly effect performance are not really prospec upgrades. The front lower arms and knuckles give 10% more steering throw and the one piece engine mount prevents the clutch bell from touching the chassis in the event of an extremely hard landing (never happened to me). The rest of the parts are machined billet versions of the original parts that are stronger and heavier. Otherwise the two are functionally exactly the same. I have a standard MBX5 and since the region I race in has relatively soft dirt, I see no need for the CNC machined parts.
