I was told HPI's shock oil weight rating is equivalent to CST exactly. For example, 40 wt = 400 CST. Is this true?

Well, I asked Hiro at HB. He said that HPI oil runs VERY thin... when I say very... I really mean VERY. He said HPI 80wt is pretty close to Losi 45wt. I have not had any personal experience with this though, so I can't confirm. Hiro is a trusted source though, as he is on the R&D team .

Yes, I noticed that. I used run 70 to 80 wt HPI oil in my car. I just switched to HPI molded pistons with really tiny holes, so I can run some where around 40 - 50 wt. I have the entire range of HPI oil, so it would be quite costly for me to switch to another brand.

Any chance Hiro may have the conversion between HPI oil and AE / Losi, or the CST equivalents?

I am going to be racing a 17.5 class and was wondering if lowering the rotating mass would be a big difference?

I was thinking of getting the Edit RC Titanium lay shaft, Titanium Racings spool and cvd's.

Also would ceramic bearings be a good addition? Are there any low friction belts?

I didn't see a US importer for Edit?

To be perfectly honest... I doubt you'll notice a huge difference. I know it looks good on paper, but whenever I've spent all that money on super lightweight parts I've never really seen it to be worth the cost. I'd save that money for tires!!!

On a side note, The HB ver 3 spool with POM outdrives is actually pretty dang light. I've noticed going to the POM outdrives gives a little more steering, and takes some of the chatter away. Most likely because they fit a little more sloppy. Not sure why they seem to give more steering though... but it's worth a shot!

Thanks, that is kind of what I was thinking.

I don't have the conversion and what I answered to Korey was all from my experiences. but actually the HPI shock oils are very light compared to losi, x-ray oils.
