Caster/camber angle

[megagame]

I've modified my suspension to allow camber/caster change.

To do that I used a lathe, stainless bolts and nuts and drill bits.

Bolts used to hold A-arm are M10 metric. Steel sleeve in a-arm has OD of around 14,6mm and 10mm ID.

I've redrilled holes in plates on frame which are holding bushings and a-arm. They are now 13mm instead of 10mm. On lathe I've used big bolt M14 and drilled 8mm hole through top of the bolt with 2,5mm offset from center. I've also cut 2mm wide groove to have 13mm dimension at beginning of top part of this bolt. This 13mm dimension will later go inside places on frame.

I've made new sleeves with 14,7mm OD and 8mm ID. Bolts holding A-Arms are strong M8 12,9 (metric). So now I have 8mm bold which could be moved within round area of 13mm diameter.

Now I can move a-arm +/-5mm which gives plenty of room to change both caster and camber. Also, holes in frame were drilled with special drill to allow drilling in inside part of plates in frame. This is because top a-arms are bolted to part which holds the wheel, and you could use spacers to have negative camber. In my case bottom a-arm could be +2,5mm from center of frame and top -4,5mm which is total of 7mm of "travel".

I've bought spyder damaged in accident and repaired averything I could with cheap parts from other cars and used solutions well known in "industry" like case above. My previous project was using BMW FS650 and using whole suspension from KTM 640 to have ultimate enduro. Now me and my wife are a little bit heavier so spyder could be potential touring machine for us but it needs to be: 1. cheap, 2. configurable, 3. user friendly (no limp mode in ANY case). Let's see how it goes.

If somebody have some requests regarding some measurements I can do that .

BTW, I've used master cylinder from citroen and modifed brake reservoir to work with original one from can am.

Erm, I have to ask... Why?

I'am repairing spyder with bent frame https://www.spyderlovers.com/forums/...from-graveyard and I'm sure I won't be able to fix it perfectly. That gives me some space for error.

Also, I believe all cars have this setub because of a reason. I've measured all maunts for a-arms and I think there are some differences for each hole in a-arms mounts. In my case holes don't have same distance from center of frame which might cause differences in caster/camber. I'm sure having adjustable caster/camber will allow to have better traction.

"Why?". Why not?

Will do, tomorrow. I will be changing bolts from stainless to steel 12.9 since these are stronger. Grease will take care of rust issue.

I've drilled off center hole in aluminum block to put it with bolt inside the hole in lathe.

New sleeve for a-arms with 10mm ID.



This is already on my bike.



Bolt M14 after is drilled on lathe with M10 drill it is cut as described before.

Not many Americans think this way anymore, in our throw it away and get a new one society!

It is general approach all over the world, especially in europe. When I look at gov regulations it is obvious that it's not common to make/fix your stuff. For example, there is no possibility in many countries to register diy vehicle. Why? I have no idea.
Another example is that normally you have only 30 days to register bought car/bike otherwise you need to pay fine (250$ which is not small in Poland). To register it must be in good, working condition and pass inspection (everything must be working within specs, brakes, lights, etc.).
How can I register my spyder if repair willl consume more than half a year?
There is no way to register car/bike if frame was bent. In my case I hope gov employees will not look at this forum .

BTW. When I'm looking for answers regarding car modifications many times I find help on American forums. You guys and yyy Russians are best at repairing damaged things and analyzing how they works. This forum is great example of it . Without this forum i wouldn't buy spyder for repair.
