I had a quote in March 2002 for 3/32" at $0.64 each for 100 qty that I was going to use for the TC3. That is grade 5 ones. 100 pcs will last for a long time.

I am going to order some this week.
Isn't Si nitride balls commonly called ceramic balls? 64cents each is not bad considering it is sold for more than a buck each. Good find John.

Yes Silicon Nitride is a Ceramic. This is the 2nd hardest material after diamond. Their website claims no lubing required as the balls are very spherically correct (round) being Grade 5 or 3 and that the ball is so hard it can work with the diff rings with no lube.

That is actually better as it won't attract any dirt towards the rings and diff pulley area. It should work longer as it won't build up grit like a lubed up one. It should even keep the diff rings better longer.

I was thinking at one time to also get my diff rings coated for all my cars (TRF415, TC3, NTC3, B4, RC12L4) with Titanium Nitride or Graphit-IC (Diamond Like Carbon) coatings but I think the diff would just never work right as you would have 2 super hard surfaces and you need probably a little give on the rings. That is why some people sand the rings with very fine sandpaper to remove the grooves created by the balls and allow some grip for proper diff action. Some people sand new rings to take the smooth finish off from the factory.

I will call Salem on Monday and post the price I got so anyone interested can call and order a bunch. If you buy a thousand and split it up with 10 friends you would probably save another 15 to 20 cents per ball. Remember that 64 cents per ball I said a few posts ago for 3/32" size, well in a pack of 1000 they were quoted at 45 cents each. I have a feeling 3mm will be slightly higher prices being metric and not overly common.

I checked their website and it's pretty cool. I'll probably opt for the tungsten carbide though because ceramic balls tend to eat up diff rings quickly, plus it might be cheaper. They said you can order from 1 to 1 million balls.

Default wheelbase question...

hiya guys!
thanks for looking in, any opinions will be greatly appreciated!
our local track is a small twisty affair. the main straight is only about 30 meters long.
does a short wheel base help in this instance?
i have ta04 SS arms i wish to try on my 415... is that a good idea?
the rear axles become angled forward , is this ok? won't this cause a lot of friction?
thanks for looking in

one of the local fast guys here once put in the SS arms on his 414...and he was wicked fast. his car rotated very well and lots of steering. this year.. he won the North America 2004 TCS Nationals. might wanna ask him how much it helped?

adding the SS arms is a lot of work.. if you have plenty of track time i say do it. if not, you can just shorten the wheelbase by adjusting the spacers on the regular suspension arms. OR if you pick up the lightweight set... it has more tuning options for setting wheelbase. you can actually get it really short.

Default jurgen diff halfs

Can someone post a website or email address for this jurgen person. I am interested in purchasing a set of front diff halfs for the 415, and I havent seen a way to get in touch with him. I am currently using the yokamo set up and it does work well but I broke one of the diff halfs, so the alluminum ones would work out pretty well. Also please do not reply with a vague reference of
"YGPM", what the heck does that mean.
