Really? The Tamiya short spring is shorter than TM's ones? I may need to try. I have a set of TM springs, the stiffest one I can use is dark purple and the min front ride height is 5.5 mm, I can't go any lower.
Yeah you diffinately need the shorter Tamiya springs if you want to get the right ride height. I had some of the standard length and found out they where too long the first time I tires them so then I ordered the springs I posted above and the problem was solved.
