Default OS's CFX Killer

Been having a lot of fun wheeling around my little CFX. I've had all kinds of ideas on modding it for better performance, but I kinda like it as it is too - the challenge is part of the fun.... so what to do?

Let's build a new truck! (any excuse to mess with random parts really...) Similar dimensions and still using a CC size body but with the performance mods I wanted to incorporate into the CFX. Sure, let's go with that.

I used this truck as the base and started mocking up a lower driveline that incorporated OD...with such a short WB, I think OD will help tremendously. Started messing around until I had a layout I liked. Proof of concept...kinda. Compared to the CFX in the background, it's much lower COG-wise.


The chassis could have worked, but I wanted to incorporate some changes, and the old one was getting holier than the pope after being modded so many times so I cut up a new one. Really, it was just an excuse to cut up some metal.... incorporated the shock mounts and straightened out the back.


The tried and true HPI reduction...used a piece of ABS to span the chassis and mount it. Seems solid, though delrin would have been better - I might come back and make an aluminum mount later that's a bit stronger.


Mounted up a Hammer t-case set up for OD. Little more OD than I would prefer, but should be ok with the kinda tiny tires. My trans ratio is only 10.89/7.41 front/rear with this setup though - definitely need more reduction somewhere. I kinda have a plan....


Axles are my last pair of TLT's with all the goodies from back in the day... MIP's, clocked C's, HD lockers, etc. I was debating a set of MST axles since they have better steering, and are the perfect size, but the TLT's were doing nothing but gather dust and the MPA axles were $100. So TLT's it is!



Front axle mounted up...it's tight, but it all shoehorns in there. Went with a 3 link w/panhard so I could drop the motor as low as possible.



On the rear axle, I swapped the truss for a Dinky link I found in my stash for more clearance.


Tight back here too, but it all works. I was worried about the driveshaft angle, but it seems ok.


Ordered a few parts, so I'm kinda stuck at the moment.

While I was waiting for them to come in, I started messing with other stuff. These old Outcroppers are going back on - they are not comp level tires to be sure, but there's just not a lot of great tires at or under under 100mm, and these seem to work pretty decent - inline with my driving abilities anyway, so using them for now...I did open them up with a dremel a bit which should help. Modded tire on the left


Pretty much it until the UPS guy gets here.
