ok got it thanks guy. i just orded the upgrade kit for mine so i guess this might have to wait. i have never heard of this companany before looks like some good parts. i think i might try the vts4 disc plates or is that diff kit a must for 1/8 outdoor tracks. i think i got my car setup good but not great. i might try for this too. [I] have the stock sc10 with sway bars. that is all.
