i found the tomy springs from qfm were pretty soft. i cut them to the perfect size and they gave me the tightest turn i've seen but it came at a cost....a bit too much speed and it flips or on a slippery surface the rear end slides out. i alleviated some of the flipping problem with a stabilizer bar to keep the spring from compressing too much and it helped a lot. it'll still flip on fast turns but it performs better on bumpy surfaces like my carpet
