I'm running pink front and rear on medium bite dirt and they are working very well for me

new to the tekno game, picked up a 410 w/ a few upgrades, truck seems much better than my losi's were. looking forward to podium and tq's with this one!!

I am running the Baker setup with this truck. On our indoor hard pack that is a bit loose the kit springs/ 37.5 front shock fluid seems a bit soft. I may be looking to stiffen the front up just a little. what should i be looking at?

OK first outing was a hard lesson in short course. Racing on the high traction black play dough at the Ohio rc factory made me realize I got a lot to work on.
Tires felt great. Ended up with pink spring in front and reds in the rear. Can't get the ride height down under 30mm. Thinking about zip tying a couple coils together.
The nose dive in this class is the most confusing. Getting it figured out I just have to jump and keep around quarter throttle.
Had lots of fun though.

Take away rear anti squat. That will really help the nose dive issue.

Just have to break everything down for cleaing, oil changing and general inspection if you want to keep these things running. Front drive shaft/universals are shot. Good thing I have 2 weeks before my next race and an EB48.3 and ET48.3 to keep me going....

I pull mine apart and switch the pin to a different hole to help with that, and keep them lubed of course.

What are you using for an ESC? Make sure you have no drag brake set and even add a little push to help keep the nose up.

I believe the nose dive issues are from front springs being too soft and rear being too stiff. Try yellow front and orange rear and slightly thicker oil all around.

With the same shock oil package,try yellow front and orange rear springs. If you can, run the ride height at 26mm/fr,25mm/rr
The box stock pistons are more for bumpy,loose track condition so you'll have to stiffen them up for tracks with more traction.

Ya I think your correct Lowe, I was having some nose diving issues on bigger jumps. I installed rear pink springs and put heavier oil and the nose diving went away

The red springs in the rear are probably making it near impossible to drive. I'm running black in the rear (5 steps down from red), pink in the front. Ride height is 22/22. 30mm ride height is a little too high .

Actually, it's rare that the rear of the chassis is slapping and kicking up. And springs can only do so much if the damping isn't correct. To help with nosing over go to a stiffer spring in front, lighter spring in the rear. Heavier oil all around. Less anti-squat for sure.

A stiffer rear spring is only going to toss it over the front quicker. Reduce rear droop. There are a lot of factors at play here. I posted some info a few pages ago about this topic.

Lol...i misread the whole thing !!
I thought he was running the pink in the rear !! You are correct mr Tekno...that's is a case of too soft in front and too stiff in rear....that causes too fast of a rebound in the rear.

Thanks for the help I do realize that 30mm is way too high for the ride height. I cannot get any lower in the front. I'm going to try to turn the rod ends in some more but I don't expect to really gain much.
I was just trying different combination to see if I could eliminate the nose down.
