More holes on the piston the faster the travel of the shocks will do. I use 2-3 holes as my base setup.

Do you guys put the put the delrin outdrives on the front diff?
If not is there a reason for this? and is it softer than the grafite 1's ie will it brake easier?

There are 2 damper sytem (may be more, but I only know these 2)....# of holes, or the size of the holes.
For Pro 4....the more the holes, the faster the rebounce speed because oil can travel thru the damper's holes inside the chamber thru more openings (holes)....if only 2 holes, oil can only travel within these 2 holes...vice versa, 5 holes, oil have more openings to travel, that is = faster damper rebounce speed.

I run the delrin outdrives on both front and rear diffs and they have been absolutely fine so far. From what I gather delrin is supposed to be stronger than graphite so there should be no durability issues. I think the reason some people think delrin is quite weak is because of TIR's spool which uses delrin outdrives, but there's a lot more force involved when you're running a spool.

What pro 4 shock piston number do you use? I still use the #3 piston as per manual. I also use 35wt shock oil with it. What piston-oil combo do you recommend for low to medium grip concrete tracks?

Well guys i just came back from my race. I did horrible, but had fun. My spring combo was awful, and i couldn't get my car dialed, but i was able to manage. Next time i'm just going to run the out of the box combo,and use my bronze sway bars.

If, you're running foam, yes.

o sorry, i forgot to mention i'm running rubber (rp30's)

When i went racing yesterday my pro4 wasn't dialed at all, there seemed to be front traction problem, the front would leave of the ground when cronering hard.

track and tires :110 degrees, rp30's most peolpe were running rp30's that day. people claimed 27's were running out of traction during the end of the day.

My setup: front: yellow/black springs, 50wt. shock fluid, #1 shock pistons
rear: stock gold springs, 50wt. fluid, #1 shock pistons
ride height: 5mm
sway bars: 1.2mm all around

your main problem is the 3mm chassis. if you have the stock 2.5 i would use that or possbily go the 2mm chassis. the 3mm is used mainly for carpet unless you really have extra high grip asphalt. try a different chassis it should help then work from there
