35 Losi oil in the rear is a great starting point. Make sure you do not have any binding in your suspention parts.

No you don't have to drill the pistons, however I am starting to play with some smaller holed pistons with a little lighter oil.
AE big shock pistons fit perfect and in a pack you get 4 1.3 pistons and 4 pistons with dimples for drilling 6 or 10 holes. Luther mentioned Jammin pistons but they cost over twice as much and they don't have the blanks. If you want to play with pistons I would get 2 packs of AE big pistons and drill away if the 1.3s aren't good.
Here is a little chart I made for total hole area on 6 and 10 hole pistons.
10x1.0mm = 7.857mm2
10x1.1mm = 9.507mm2
6x1.3mm = 7.967mm2
6x1.4mm = 9.240mm2
I am not totally sure on this however the 10 hole pistons at 1.1mm should have similar static feel as 1.4x6 but the smaller holes should have more pack. I am going to play around with this for a while soon.
On another note, I was putting together some new rear shocks last night and when you crank down the seal cap it seemed like the seals were too tight. If this happens, I ended up sanding the little white seal from 1.1mm to 1.0mm. On the black bottom piece I took this from 2.6mm to 2.3mm grinding only the big side which faces the seals. After this I lubed up the seals, re-inserted the shaft, and it was much better.

good info on the shocks.....my son tq'd the open class at the rcpro series west here in socal at revelation raceway this past weekend....ended up second place at the end....car is nice....I have been doin this for a long time and I never ventured out to try an off brand except when I drove for SVM CRONO...But you guys have a really nice car here...good luck to you all. Hope me and my 11 year old can get this car noticed..........
