Default Ofna MBX R2 *or any* Ofna buggy HALP!

Like the title states, I'm looking for a good starting point for the shock/spring setup, ride height, and anything else that might help my nose diving issue.
20+ years bashing R/C's, this is my first 1/8 buggy and first season racing.
My chassis is custom and slightly heavier than stock.
Running stock blue shocks.
Silver springs - I'm assuming they are stock, manual only shows 32330 red and 32340 yellow as option parts and no # listed for std springs..
60WT frt / 40WT rear.

So far it's a lawn dart on the jumps even if I stab and hold the throttle off the jumps, it only wants to nose down.
I've driven my MGT8.0, Savage XL, and RC10GT on this track and they all handle fine on the jumps.

Any tips are greatly appreciated, hopefully this ancient buggy can give me some good times on the limited budget I have!

Lawn dart no matter what? To much rear spring and shock. First lite'en up the shock oil to maybe 25-27. Then maybe softer spring. Make shure ride hight is set dog bones level on rear. Check over the shock's real well, could be some bind in there. And down load the Hudy set up papers, it will alway send you the right way.

make sure the droop is set right. if that car has the ability to set droop?

and if possible get a little more updated car that is made for racing asap if you plan on racing for any length of time. there are some really cheap cars for sale in the forsale/trade thread. i just bought hyper 9 for 150.

I have the droop screws set per the Ofna manual...

And yes, for the $ I put into this thing so far I shoulda just bought something new... live and learn.

I've only gotten to practice at the track once so far due to crap weather lately, I'll try to get out tomorrow if it don't rain and the track isn't slop from the last rains..

I ended up using stock MGT 8.0 blue springs in front, 40WT oil.
Homebuilt HD Tmaxx springs in rear, believe it was 40WT oil in there originally.
With preload spacers, rideheight is waay above dogbones level.
Slapped some Badlands tires on it today, which upped the ride height as well.
Handled like a dream lol!
