You also need to cut the Ofna pin evenly on both sides for it to fit inside the diff case.
so how long u guys been using this ofna pin setup??? i am getting sick of trying new things and waiting.. just want one final setup that will work without issues???

My favorite setup is the 2650 on 3s. The 2200 is quite a bit heavier than the 2650. I thought with the extra weight the stock setup was a little soft and I could get better handling with stiffer springs. Stock shocks with gold springs up front would probably work well.

At the time gold springs were out of stock and I had some HB shocks, so I decided to use those. I put Associated 16mm front silver springs up front and Associated 16mm front black springs in the rear and it feels dialed.

I never have to worry about stripping a screw and especially when I'm at the track and patience is out the window and I'm going too fast.
Ya that gets me too. Might have to bite the bullet and get them

Yes number 5 is in the pack. It has the biggest holes, not more holes.

On a real windy race day...where should body be mounted? How low is too low?
Or does it matter? No holes in body cut

I like the aluminum screws idea but like the benefit of the strength of titanium over aluminum any day especially for such small screws, to each his own.
And don't you mean 8-32

The piston pack has 2 each of 1-5, for a total of ten pistons. The stock pistons are #3 front and rear.

sorry if this is a dumb question but I dont know anything about what certain pistons do, but when you go up on the # of the piston what does it do?

Just drill out your stock piston with a #56 drill bit, that will get you to the number 5 piston size. #56 bits are supposed to be 1.18mm instead of 1.15mm according to the charts, but all the ones I have mic'ed have been 1.15mm.

I like the way they feel personally, give them a try.

alright, but what do the different pistons do is what im asking, do they make them like stiffer or softer or what?

Piston hole size determines your high speed compression or "pack" in RC terminology.

It will also make the shocks softer if you use the same shock fluid, but usually you stiffen the shock fluid when you go bigger on the holes.

37.5 front/32.5 +/- 2.5 is pretty good with #5 pistons IMO.
