i have read about every post on a arms and im still dont know if one brand is that much better than another. i think alot of people just praise what they happen to be running. i see alot people get the lsr arms, maybe because bob gives a good deal on them along with the tcs shocks. i also think some people just say one is better than the other cause that what the pros are using. i have just recently starting racing mx and have never had the oppurtunity to have aftermarket arms. i had a z400 last year and did pretty good at the local tracks with stock everything. i will also have to use my stock suspension this year since im pretty much broke due to buying the yfz and putting the basic parts on it. i plan on upgrading my suspension and stuff next year and wouldnt mind paying extra for the higher priced a arms and shocks if it is really that much of a difference. anyone with experience in this i would appreciate your input.
