oks, i made a rear suspension, but it isnt a Tbar suspesnion....i guess i got side tracked while making it and made something totally different that works wonders...
i call it a "V" suspension system

i removed the tabs that hold the rear to the main chassis..and i noticed that when i skrewed the rear back on, it pivoted [sp?] back and forth.....and i was like whoa...
and what i did next helped the most, i took a spring from a cheap mechanical pencil, and stuck it horizontally between the pivoting point, "the V"...and to my amazement, it was awsome....
what was even kooler, is that if i tighten the skrews, i can actually harden/stiffen the suspension...
now the performance is friggin awsome, it actually seems faster...because it puts the power down
