i was contemplating the idea of make some plus 2 or plus 3 arms for my trx250r. the only thing is i want it wider and not want to move it forward like a +2 +1 kit. i think i would base them off the stock arms and incorporate better materials. i plan to use 4130 chromo of the same thickness and size as stock. just i want my 250 to be a bit wider and i dont want to dump 2000 dollars on a kit when i think i could make a simple one for way less and uise the things i have lying around. i know this could be dangerous but i have plenty of mentors to guide me and i would like to start a project like this because it seems to be simple enough and not as complex as teh sand rail me and my pops are building.what measurements wopuld i need to take into consideration and what ball joints or heims would you guys recomend? thansk and this again is for a senior project which is required for me to graduate and this seems like a more tangable thing todo than try to build another sand rial by myself.

I would use the new laeger style ball joints. JD, JB, Alba, Houser, and others also use them. They are inexpensive, strong, and all sealed up. The open style ball joints and heims are a pain to keep clean and lubed. The most important thing when making arms will be the castor. If you put heims on the upper a-arm pivots, then you can adjust the castor. If you just put bushings on the upper pivots, then you will have to have the castor pre-set in your jigs. Castor will greatly affect the handling and it needs to be right.
Walsh used to use heims on the inboard pivots for the top and bottom on mx arms. They were able to adjust for wheelbase that way using different length spacers to move the heim farther forward or back.
Ricky Stator has a lot of ball joints. I like the new style laeger ball joints the best. You could use them for the ball joints and heims for the inner pivots. I think that would be a sweet set up.
Here is a picture of some laeger's with the newer style ball joints.
