I just found your site.VERY cool! I want to put
the new big bore shocks on my 777. I have a race coming up in early Nov. and
don't have alot of time due to my work to experiment with setting them up. Do i
need to use different weight fluids as opposed to the old style "skinny" shocks?
I currently use 60wt. in front and 40wt. in the rear with progressive suspension
reservoirs and K-factory medium springs.
Any help would be great!!

Thank you for the compliments! I love your question.
Although none of us at Infernosonly have used the K-Factory springs or the
progressive reservoirs on the old shocks I can tell you a few things we have
found out from our testing and racing with them over the last month and a bit:
1. The light green springs are very similar to the dark blue springs from the
old shocks, so under most conditions they are the ones to use.
2. As conditions
get rougher a few of the guys will start using the purple springs in the rear.
If conditions are real rough and dry purples may find there way onto the front
as well. The purple springs have the nickname "purple pothole eaters."
oils translate almost directly from the old shocks with the stock pistons (1.4)
using the pistons that come with the Big bore sets. So we find ourselves running
Kyosho 700cps(about 60Wt Associated) in the front, and Kyosho 400(about 35Wt
Associated) in the rear to start out and adjust as the conditions warrant. Much
the same as the old shocks again. Don't forget to factor the temperature of the
air in when deciding what oils to run as they thicken as temp drops.
4. We like
using the Cody King base setup to start our test and tune sessions with; as
posted in the downloads section of the site, (Cody King Base)
Just put the Big Bores on with the green springs with this setup. If you haven't
tried this yet it is a must!
5. There are more spring choices coming out soon
but so far we don't see much of a need for them on the tracks we have been
6. The new shocks seem to react a bit slower to everything compared
to the old ones, but playing around with pistons seems to have some affect on
it. The handling of the car seems less affected by this than you at first would
think. I have to say, I have now personally raced on 5 different tracks with the
Big Bores and they are working great! I have had no problems getting the Big
Bores dialed. The car is more stable than before, but has not lost any steering
in any way. It actually seems to have a bit more steering than before. Rough
sections that unsettle every other car are no problem. You must change your
driving style a bit to find some of this out however, you can't be timid through
rough sections as before, you just have to let the car pound through them,
actually it is impressive! Anyway, I could go on about this, but there is other
work to do! I hope this helps! Please give us a call and ask for Trevor if you
have any more questions.

I don't have them but I would assume that with the
increased volume you could go with 35 in the rear with green springs and stock
pistons. For the front I would stay with 60wt oil and stock pistons. Maybee play
around with the preload to get it to settle back down sooner and maybee go to
the next stiff spring than green. Jump the car and see what happens on landing
to the front end. I like to keep the nose up out of the dirt so if it feels too
stiff on the bench go to 50 in oil it won't change as much as the smaller shocks
in a long race. Have fun and remember it takes time to get new shocks broke in
and tuned perfect.
