Default Front Arms

We built one of the new IFS front ends to day at the track and used the Exotek upper arms so those of you using the Exotek upper arm I've got some info for you:

If you use the stock spacer above the steering block then the rim will rub on the upper arm on the back side. We lowered the upper arm spacer by about 1mm and added the difference above the arm to keep everything tight and that helped it stop rubbing for the most part. But the rim would still rub in the corners just a bit sooner so we were not getting the same amount of steering throw than with the old arms. A little more lowering of the upper arm might be needed to use the Exotek upper arm. For those using the F104 steering knuckle you will probably have better clearance if you are using the off-set axles.

Handling wise with just the initial stock setup the car looked like it did gain a little bit more steering than it previously had. Not as much as I had hoped but some is definitely an improvement. I think more front grip will be able to be generated by using a lighter oil on the damper tubes than stock. It will be interesting to see how the setups develop around this front end.
I put my IFS on in the last few days and noticed the interference you mentioned. Although I have not run the car at all I believe I took care of the problem by moving the rear link to the bottom of the forward link without changing the kingpin spacers. Seems to clear the stock wheels from lock to lock. I countersunk the hole in the forward arm like it is on the bottom and used the flat head screw. You probably could get by with a button head.

I don't know if there is a problem with this but so far, so good.

Just got back from the first shake down run with the new front end and I am impressed. Let me give a little background info on my fgx. I am running a McKune lower chassis, exotek upper arms, f104 front spindles and wheels, pit f104 tires all the way around and 3racing NFE. For kicks I left the 21.5 motor out and bolted up a 17.5. The NFE actually produced enough grip to handle the extra power and still navigate the tight carpet track I race on. For the first pack I set front ride height at 4.5mm with .5mm droop. 4* caster, 1* camber and the included tube lube(very thick). Car felt really good, steering was a little more positive feeling than I remember and best of all, no hop or chatter when pushed hard. For the second pack I geared up a little more for extra speed and the only FE change I made was going to 30k tube lube in the front shocks. This made the front in just a little more aggressive for corner entry.

Also had a few run ins with the boards and other cars at speed and nothing broke. So in my humble opinion this new front end is a win!

Any 103/104 will fit, just need to ream the holes a tiny bit bigger.

Just curious - are most of you running a shorty LiPo, or standard size? I've yet to run my car, but have it sitting on my bench with one of my standard packs in it - it fits well, but obviously won't offer the same adjustment as the shorty. What's preferred? Going to be racing on carpet - we're running 21.5 on rubber.

Get shorty

Moving the battery forward or back makes a big difference in handling and is a great tuning option.

I have the shorty pack too but more for real estate and less for tuning. I have it all the way forward and never tried moving it from there. With the short pack forward I can mount the reciever, esc, and cooling fan all behind the battery and closer to the chassis center line.

Default custom fitted IFS on my Exotek FGX

exotek upper arms with lower arms that came with the ifs kit
drilled two 45 degree holes into camber mount to secure the two-way
drilled two small holes on the top plate to secure the dampers

haven't taken it out to the track yet but at least it looks cool

nice, it looks good. i see you took off the second carbon piece to mount it. id be curious to see if it allows the car to flex more. im considering cutting my upper deck like a f104v2 to allow for flex. i want to see what exotek come up with before i break out the dremel.

That looks great Xana...how did you mount the bell cranks on? Did you just drill into the metal suspension mount at an angle?

FYI...your rear shocks are backwards

Looks great! How about a pic of the mount with the holes showing?

Thanks!
