Couple of glaring issues...
Shock mount locations: I'd put the rear/lower mount in the outside hole. I'd put the upper mounts more upright in the third hole location inside to outside.
Shock springs: A lot of times the front spring is stiffer than the rears; Blue/Silver is common.
Number of washers under the front ball stud mounts: On the front does that really mean 4 x 20mm? Or should that have been 4 x 2mm which is still a lot. 8mm?
Something else to consider: Dual rate on your radio. I typically turn mine down to somewhere betweenn 70% and 80% depending on track.
I'm sure others will chime in about droop, anti-dive, anti-squat, ackerman, etc.
