"out of the box" shock oil doesn't follow the manual.

So I'm pretty sure Corally isn't following their chart in the manual and just ships everything with 600CPS oil (this is what the "ready build" shocks come with). I put 1000CPS in front and 800CPS in the rear as per the "factory" setting and the suspension is now a lot stiffer than before. I thought it was the tighter seals that were causing it but when I changed those out the suspension is still way harder than it was with the shock oil that the car came with.

Corally get lots wrong in this dept. I just discovered that the front upper hinge pins are different there are 2 types. Asuga uses c-00180-891 but in spares for Asuga they list c-00180-127 which is wrong it would be too short but it’s what I need in My build the Asuga pins are too long I’ve discovered. Need to triple check what corally states in there manuals etc

Same deal with the Shiroi manual it shows the same lower hinge pins front at rear but the rear ones are 2mm shorter than the part number given which is apparently the front and I'm still not sure what the correct part number is for the rear pins. The front pins will "work" for the rear but they are 2mm too short and not really correct.

On the plus side 800 CST shock oil seems to work well in the Shiroi, I think the 600 is too thin and the 1000 given as "factory" would be way too heavy for anything but ramping to the moon.

I've also found that Corally's O-ring sizes listed in the manual are actually wrong and won't work if you buy generic o-rings. You can use generic o-rings but you have to experiment a little.

Checked the manual for Kronos, kagama & shiroi it lists c-00180-322 for the pins front/rear which is 68mm x 4mm but if you look up pivot pins you can see there is a pin c-00180-1217 is listed as rear pin for the kagama & is 70mm x 4mm, so that’s probably the pin you require the games you have to play with corally part no.s is a bit of a joke at times. Ive saw some people just lowering the shiroi say it drastically improves handling & less roll overs

I have no problems spinning it 360 degrees at speed on asphalt so idk what people are getting on about. Could be the tires I'm using harder 125mm tires not the softer stock 120mm.

I'm not sure what shock oil came in my kagama4 or whether it was the documented oil or not but it was embarrassing off-road when I first got it, too such an extent after my first few packs I was ready to box it up for eBay . Glad I stuck with it and sorted the suspension though.

Tuning suspension is the best time anyone can put into this hobby.

So I changed over to 800CPS on the front shocks and 700CPS on the rear (the "offroad" recommendation in the manual) and it makes a noticeable improvement in handling.

sounds like the builders at the factory just throw in whatever they have. There really is no incentive for any manufacturer to not get this correct as it saves them nothing and it makes their product perform horribly.

I’m changing the oil in my spark for the first time this week. Should make a world of difference considering I can feel a lot of air in them. Feels as if they are halfway filled.

Good luck, hopefully you see improvements
