Default Guido2 Griz's U4RC Go Fast Wraith Scaler

Well it's been a while since I had time to even touch an RC.
Some friends at work have been running short course trucks lately and convinced me that I needed a go fast rig. The only thing I wanted to spend any money on was a U4RC rig so I decided I had time to put something together. It will be interesting to see if it can keep up with the short course trucks and EXO.
I don't have time anymore to build something from scratch but I figured if I started with something I had I could modify as I go. I have a PSC Wraith sitting around so I thought that would be the perfect starting point.



I've been planning to do something like this for a while so I had an Ebay Deadbolt body laying around. The plan is to 3D print my own grill to make it look like a Bronco.
I had an extra Wraith axle housing so I took the rear steer components out of Guido because I wanted to get rid of the rear steer anyway.



The Axial Wraith sway bar worked out great with the placement of the axle.



After playing around with links I liked the stretch I got from Traxxas #5319 Revo pushrods.
Amazingly the HPI A718 shocks worked perfect after I laid them back to the furthest mounting hole in the chassis.



I'm liking the overall look so far.

SSD Yeti trailing arms came in and they worked out great. They stretched the rear just right and the shocks worked out easily.



I had to go to a longer spacer to push the shock away from the chassis just a little bit since I had to move it to the forward-most hole in the chassis. I used a Traxxas Jato rod end ball and it was perfect.
This put this shock nicely vertical.



The shocks are spaced a little bit wider at the chassis than the axle but I don't think it will be an issue for now. Eventually I plan to redo the back half of the chassis anyway.
The SSD D60 centered rear axle is an amazing part. I am so glad I decided to go with this thing.



The Axial Wraith front sway bar worked out just great on the rear end.
The rear shocks have tubing limiting the droop right now. I will have to remove that and then play with how much droop I want.



The wheelbase looks great to me and it is under the U4RC 15" max for the 2.2 Solid and 2.2 Unlimited classes.

I'm game. Hopefully I can make some time.

So I'm needing to buy gears; should I get the standard ratio or the OD gears?

Thanks Adam, I have not had a chance to touch our rigs since Axialfest 2016. Heather and Cody's rigs still need the motors replaced.

I've been planning this build for a long time also. I thought it would be fun.

Under drive front and rear. Little less torque twist and the strongest pinion and mesh of the 3 gears.

Oh, ok. Sounds like good reasons. Thanks for the advice.

Standard ratio up front in hd. Ud out back.
It pulls the front around really well, and helps keep the front planted.

Sweet Wraith!!! I've been thinking about Yeti or Bomber Rear Lower Links.... still can't find out if they're the same length. (Yeti and Bomber - I know they're both longer than Wraith!)
I like the idea of having some more "cush" in the Rear Suspension. The stock Wraith, even with 1.22lb Springs, still feels too fitm, and won't let me get more than HALF of my Rear Shock travel, especially with the Front Battery Mod!!

I'm not making a serious Comp Rig, but as a former 1:1 Racer/Builder, I want the best dialed Suspension - even in my Tiny Trucks!!

Outstanding Builds like yours are helping me achieve that! Looking forward to seeing where your Wraith goes!!
