Help I Keep Breaking Front Arms

With the K2 Schumacher sarted using an adjustable hub design that required
a relief cut in the arms for the steering knuckle to clear. The easiest solution
until a revised arm is to run the old style arms without the relief cut. Run the
hubs in the High position and set your steering end points down so the steering knuckles don't hit.

SCHU3597
SCHU3407 MED Flex

There is a newer batch of the SCHU3407 wishbones which correct the weakness in the previous front arms.

Suggested upgrades/spares
Strongly suggest to buy 10° alloy front alloy pivot blocks-U3556 the A & B front plastic pivot blocks-U4798 will break soon.

Have some shock seats spares, alloy v1-U3611, plastic-U3937, alloy v2 (off-road)-U4890

Have some spare shock shafts available U3668 & U3669
MIP pucks an Excellent option!

Misc

Other wheels that fit apart from the Schumacher wheels
Losi 22-4 wheels will fit on the front the rears will work as well!
AE b4, b5 & b6 will fit on the rear
Be sure to lock tight the track screws and rear strap this is a must!!!

AE (12mm) and KYO fronts will work with .5mm spacer - available through AVID


Don't buy the purple titanium turnbuckles as an upgrade there thread is too small and they wander too much. Lunsford Super-duty titanium turnbuckles fit very well they are 3.5mm threads. Get the 1 3/4", 2 1/8" & 57mm lengths. I did not replace the Centre Track Rod.

** When running the Super Duty turnbuckles with the stock captured ball ends, be sure to check for binding in the front steering and camber links after each run - tumbles and glances off the pipes cause them to flex and slightly twist and can bind up the front suspension ... The fix? - simply take a turnbuckle wrench and twist the link back and then forward to it's original positon .. consider doing this as a maintenance step after each run ..

Suggested Gearing

5.5 - indoor high bite clay 83/20 (+/- 1 tooth for layout and conditions etc)
6.5
7.5
8.5
9.5
10.5
13.5 At SRS Arizona I ran 75/28 buggy was quick! RCM lockout worked great!
17.5 - FDR between 5-6 depending on track. E.g. 35/66 down to 30/69 slipper eliminator in use. Different options within the thread. I use B5M exotek eliminator and file it to fit.

Dear goodness, could he be any more boring and timid sounding?
I find it to be a Meh overview of the NEW product.

Still I can't help but have Heart eyes when I see this thing. LOL

Did you expect him to shooting guns into the air &'saying yehaw to make it sound more exciting? He's a bloody good lad is Trish, dead friendly & helpful, even if you don't run a Schumacher. Bloody good driver to.

Chillax there a bit… I LOVE this car.

Nice guy or not, I just think a product such as this deserves a bit more pizazz. There's a lack of passion in the presentation. Is it so wring to say so? Geeze Louise.

Good luck with that! I don't know about them ball studs look's just like Serpent's ball studs which I hear have binding and breaking issue's? Maybe that's why there are so many washers which i think is a lot to deal with. I will replace them with lunsfords ball studs and Schuie ball cups never an issue with this!

I've purchased B5 studs (8mm and 10mm) and cups in advance, not knowing that the K2 would have these new captured ends, but I like them. I'll be ready to swap them for the AE set if they end up binding. I am also going to stick with the B44 wheels, I'll pick up U4321 and drill the centres out to the axle diameter and then glue in the 0.5mm spacers. I'm looking forward to getting my build on. This will be my first Schumacher since my 2000 Team Cougar!

...I believe the photos available on petitrc are all taken before the new captured ball studs and cups were available or issued, but like anything else, time will tell!
