I just rebuilt my shocks on my RC8.2e. I changed pistons from stock 1.2x8 to 1.3x8, replaced stock silver springs with Kyosho blue, used oils: 40 front, 32.5 rear. Rebound is 50%. Now when I drop the car from like 10 inches, the front slaps, hits the ground, the rear settles very nice though. When I press front by hand the suspension comes back very fast, when I press the rear it comes back slowly. Front feels much softer than rear which should be opposite as I used thicker oil in the front. I am a rookie in RC so I may be missing something. Or maybe I need to drive my buggy and then check how it reacts?
I use stock towers and stock setup mounting holes. Ride height is 29/29, shocks drop is 101/119. What am I doing wrong here??

If you read the thread starting at the link at the top to page 6 it should answer all your questions.

I'll give you a general idea of what of what you are dealing with.

Remember when you rebuilt the shock. There were the discs with holes in them. The holes allows oil pass through.

Lets say the holes were really big. The oil will pass through very easily. If the holes were tiny then it would be difficult for the oil to pass through.

This will dictate how fast the shocks will compress and rebound.

So when you drop your rc8 the shocks are hanging mid air. This means that
The disk is at the bottom of the piston. When it hits the ground the piston/disc wants to move upward but it takes time for the oil to pass through the holes.

This is the slow movement up which cushions the drop.

Your problem may be that you have air is the shocks. The air will go through the holes easier than the oil. This is where oil thickness comes into play. Thin oil goes through easier than thick.

The springs are another aspect to this process as it help in the process.
