Did mine the same way. Looks awesome, but took FOREVER. Can't wait to race this thing tomorrow!

if they are gun metal, where'd they come from?

got half way through the build last night, the instructions leave alot to be desired but it goes together like PB&J. excited to get it done tonight. still torn on which setup to throw on it first

i have to wait until our track is rebuilt to check out the dirt and layout.

thank you,

@ Stockman

Those red accents look awesome! I'm assuming that's aftermarket? If so, who makes them and do they have other colors?

Ya they are aftermarket. There are many different colors, just ask your local hobby shop or you can find them online. You will also need all different bolts as they will not use the OEM bolts.

Rack is a concern. Broke one after about 6 packs in practice, and the hit was not hard. Broke at the transition between the horizontal mid section and the vertical ball stud mount. Have one spare for the weekend. I don't think towers will be a major issue.
