Default Let's see your setups...

Hi all, having some issues with my suspension tuning and was wanting to see what others have come up with to help combat the torque twist. I'm running an Axial with the stock chassis. So far I have the stage 2 on it with a basic close mount 4 link setup in the rear and i have some ideas about some changes, but i would like to see what others have going on with their rigs. One thing I noticed is when I rotated my front diff to straighten out the drive line, the twist came back with a vengeance.
Please post some pics and share some knowledge.

Thanks alot

Erik

i am also starting to notice issues with the torque flex. I am going to start this weekend with a new steering horn to replace the striped plastic one. Things i have conisdered to help with the torque twist/steer is going into a longer spring in the left hand side, or changing into a heavier spring. I may end up going to heavier springs over all to reduce my overall flex. From what i have seen 1 pop can and a little more is ample flex, and that will help with the drop out i come across in my playground. My course is mainly riprap (12-24" smooth to jaged rocks around culverts and drainages). Often times i would like to be able to float a tire over a gap versus dropping down.

I am also going to shift some weight around and even take some weight out of the rears. in need to be able to have the front drag me more often than the rears push me over.

I've never cared for short upper links and most link mounts made are designed around short upper links. Long equal length links will provide a smoother reacting suspension. Short uppers will push your pinion towards the dirt on droop. This mount is designed to run stock Axial straight lowers as uppers. Either run bent or straight lowers to have equal length links. Equal length links will keep the pinion angle the same throughout the suspension cycle. I've always dealt with Torque twist in the shocks. The side that squats,try a stiffer spring and/or thicker oil.

This mount will lower the mounting point of the upper links compared to some mounts. What that does is give you less vertical separation between links at the axle. Therefore giving you a touch more antisquat. That helps the rear from squating so easy on acceleration.

I've also found you have to run a really flat pinion angle when using short uppers, angling it up seems to make the TT much worse. So I don't run short uppers anymore.

The asymmetrical mounting points at the axle can help with torque twist too. If I were using this mount with a stock axial chassis I would have moved the uppers back a hole. I'm using the Mayhem LS2.0, it's upper and lower link mounting holes are closer together front to back, which I prefer.

Cool, starting off with some good ideas. I have the stock chassis but I drilled new holes closer to the center for longer links and try to get the lengths closer. And yes, I found that running the diffs above level increases the twist alot. I have also noticed that everything on these things that increase performance in some way will have a drawback somewhere. Like chasing my tail.
I am running stiff springs with spacers on the front right and rear left at the moment. I had the twist down pretty good till I got new tires. Then the increased traction brought it back. Then I raised the front yoke for more clearance and the twist got worse again. My next attempt is going to be to drill a new hole in the chassis to raise the chassis end of the left rear link up about 1/4" or so to see what that does.

Does noone make an axle with an offset input shaft?

A little big for 2.2's,but they can be done....a Twin/Mad Force axle can be modded to any width you want and can place the diff anywhere you want on the axle.

my pal djmedic replace the 4 link bars with stiff adjustable springs, and it COMPLETELY eliminates it, and ive seen people add limiters, that works, but it makes the springs pointless

I'm running a partial "Stage 2" because I wasn't impressed with most of it.

homemade 4-link plate rear with turnbuckle upper links going into extra holes drilled along the trailing edge of chassis below the row of stock upper holes, left link mounted on standoff above link plate.
