I am lookin at my TC5 right now...not sure what surface your running on but mine is set up for carpet....I am running basically out of box setup w exception of the sways mine was loose I removed them and made a big difference....my ride height is 4.5 frnt and 4 Rear...Droop 1mm frnt 2mm rear and make sure you check your tweak that will create several issuies....Tires I am running Dbl/pink rear and dbl/pink/orange Frnt.....you could run pinks in the rear or try stiffer Frnt springs......Craig Drescher setup on associated web site is close to mine and my car is nailed to the track......My 2CENTS hope it helps...
