Default Suspension block dimensions

I'm currently busy with a custom project and i'm looking for some already made suspension blocks which will fit my needs.

I need a block which has centre to centre distance (for the suspension pins) of 32mm.

So if someone knows if a manufacturer has a suspension block which has that size could you let me know?.
And if so I would like to have some dimensions of the block so I can put in Cad straight away.

So I need this type with 32mm from centre to centre:

32mm is really narrow. Not sure you'll find any that narrow. Have you thought about stand alone suspension blocks?

What's in it for me?

OK, I'll let you off if you promise not to deplete supply for me just yet.

Kawada Sigma2 has such a suspension block. Total length is 50mm, profile 8x6, screws outside the hingepins at 44mm centre to centre.

Good luck.

The Schumacher Mi2 had 2 suspension blocks per suspension arm. If you take them, you can use every distance you want.

Basically anything like that is possible with any current 2-piece suspension blocks from any of the Corally, Xray, TRF and so on. One piece only, see above.

Der Dicke! hahahaha! that's the greatest screen name. I love it. Does it mean what I think it does?

Thanks for the suggestions.

Did some searching for the Kawada blocks, bit didn't find any. Car seems to be EOL. Only found a part number, bot not one shop who carries a single part.

The two-piece blocks would be plan B or C. Don't like the idea of having two separate pieces, makes it weaker and causes the possibility for misalignment.
But on the other hand it will make it easier to incorporate into my design and won't cause any clearance issues with the drivebelts.

Try harder.

http://www.kawadamodel.co.jp/

Brush up on your Japanese knowledge and you'll find the relevant page on their website.

Ask then RC-Champ (present here as sponsors) from Japan to send you some. C'mon don't let me do your entire project. Sweat a bit. The parts are still very much available and so is the car together with its newer sister, the Sigma2 V2.

Went to the Kawada site, there is where I downloaded the manual to find the part number.

But I will contact RC champ.

But again thanks for your help. Started already putting the part in Cad.

The blocks Corally uses on their 09 Phi look quite ok as well. Only it would be tricky to change the rollcentre and anti-squad by shimming I think.
Maybe order a set of the Corally ones as well.

The PHI 09 uses two piece blocks front and rear.

Shimming is actually a lot more accurate than anything else because of the more easily repetable machining involved and it can change both roll centre and anti-squat without any other part being touched. Setups such as those used by Xray or the older Corally cars are a lot more susceptible to machining/molding errors.

Tamiya TRF split blocks for the TA05 would most likely work great. They still come in all the different widths that the normal blocks do, but you could set them at any distance apart you want. Start with mounting the 1X blocks at a 32mm distance, then you can go 1A, 1B, etc. or 1XA, 1XB, etc. to widen or narrow your pivots. as needed. The 1X blocks are Tamiya # 54171.

Sorry I meant how I would actually be able to raise rollcentre and change anti-squat. From my Serpent S400 I remember having big shims which you place underneath the blocks. But now I went through the Corally manual I discovered they have shims for this as well.
Also different types of suspension blocks.
I fully agree that it is a far more accurate way to mount and adjust the suspension, was really impressed when I got my first electro tourer (Serpent S400) and asked myself why this type of suspension isn't used in nitro cars.

I've seen those when I started my search for some fitting suspension blocks, but if i'm correct there aren't any shims for the two-piece blocks, only found the one-piece shims which are used for the TRF416. And I really want shims to change rollcentre and anti-squad.
They are nice though. Would rather have the aluminum Tamiya ones instead of the plastic Corally ones.

How about the HB D4 suspension blocks. Might have to pop over to the off road section and ask those guys...

HPI pro4 has that type of suspension blocks you show in your pic and also they have shims to change the roll center and anti-squat. You can still look at the instructions on their web site

You can use normal round shims through the screws to raise the split Tamiya blocks. You stated before that you don't want to use them because they are weaker. It's quite the opposite. It's nearly impossible to bend or tweak the two piece mounts, and I have seen some really bent up one piece mounts. I run the splits on the front of my 416WE.

That's actually no issue at all, you can just use standard shims with a 3mm hole. I run those blocks on the front of my 416 raised 1mm with standard shims. Tamiya makes shims as well, so if you wanted a matching blue, it's easy to get.
