Rb6 pistons
 

Hi guys I'm currently finding that I'm struggling to get the rear of the car soft enough with the standard pistons which in wet weather I'm struggling With rear end grip when accelerating out of corners, don't get me wrong it's decent but I'm really having to feather the throttle carefully and I know there's mug more grip to be had in the wet. I'm using the right tyres (bb mini spike green also) In the dry this isn't as much of an issue.
I'm currently running AE 27.5 oil with the standard pistons drilled to 1.4mm in the rear with losi yellow spring and it still doesn't feel soft enough to me compared with nick caro's. he's using a type of rounded piston but I can't remember what that piston is.
Any other pistons that you recommend over the standard ones?
Cheers

Try standard 5 hole piston with 25w Losi oil - very good and car is just awesome.
Also try the standard RB5 rear staright rear wishbones.
You will find the car stands up more out of corners without it trying to collapse.

Cheers tony, Carl and nick both told me about the wishbones. Also seen atushi hara doing it too

I think some are also drilling a 3rd hole on the wishbones.

Have you tried increasing the anti squat and shortening the rear camber link on the hub. I found this much better, making the rear end stable in the wet
