Thanks bro! How was San Diego?

A bunch of my track mates were down at WCRC for the koproppo race... I just didn't quite have enough time with work to be able to bring my gear and race it... I wish I could of while I was already down there!

There are a handfull of parts from the rb6 that are actually rb5 parts, and are only listed that way (so far anyway)... so take a look/search that way and you will find them, along with any other part from the 6 that is shared from the 5.

Lower shock eylets
http://www.amainhobbies.com/product_...c-Ball-Ends-12[/QUOTE]


Thank you, but aren't these all the same length? I'd like to find the Small Medium and Large "Ball Ends" (shock ends) to tune the droop.

Run the stock length shock ends that come with the car. That of course is medium in front, and long in rear. If you want a little more (which maybe you might want in the front), just unscrew the eyelets a turn or so. In the rear, the long eyelets provide quite a bit of rear droop, which this car likes. It helps with rear traction in the corners. If you need a little less, run a limiter.
