Thanks.. also to note other differences.. the braces front and rear that hold the a-arm pins, the a-arm pins are also upgraded, the hubs on the wheels are upgraded and as noted above the shocks are alum top and bottom and the chassis and shock towers.. quite a few goodies actually.. but for what I spent - the dx2, - the sr3000, - the servo's - the nitro parts even though I'm getting a few other upgrades it's way cheaper. I just found the losi "pro" or upgraded chassis new on ebay for 39 bux +ship and the shock towers I snagged from that
dragon racing ebay shop for cheap and look at least as good as losi's w/ even more mounting options. So I will dump less than 80 or so back into it for some upgrade parts... rest can stay ;)
