Manual has the hole furthest away from the kingpin which widens the track...
Yep... stock setup is the wide track setting.

And considering MIP drivers last upwards of 25+ years... id say $14 is a bargain... seriously.
I couldn't agree more here with capt america. I have slowly switched over from Hudy to Thorpe/MIP. I have tried Wesa and no luck for me. Too many times where I had to bring out the old trusted dremel tool to get a screw out.

This tool info is good. I have had extremely great luck with a set of dynamite hex head drivers. Not the plastic/ rubber handles ones but the ones that are red anodized and knurled handles. The hex head is as sharp as the day I bought them 2+ years ago. I think they were around 8 bucks per driver. Ergonomics aren't the best but it's manageable. Looking at them now, I don't even see a wear mark on the hex.

Very interested in e mip ones.

Default lastnight

the car felt so good lastnight, second day out at practice with it and i love it!

also, i drove a buddys who had a mid motor setup.. it was very fun and so fast in the corners, i had nearly just as fast laptimes. but the car gave up rear traction like crazy, i had to baby it and really work on precise throttle controll ( compared to my stock rear motor i can hammer on) I suspect if he could settle the rear down, I would be faster with it no doubt. he had a shorty in, maybe saddles, maybe a few weights? either way both configurations are a blast to drive, what a great car!

heres mine

I think a bomb went off leaving just the partially assembled RB6 intact.

Picked up a second RB6 off a buddy of mine! He just picked up a proline ride and is consentrating on SC for the time being. Used for only $250. For that price I feel like I won the lotto! Think it's been used less then my current one! LOL

Don't know. I didn't really inspect it but I do know he was running the tebo shock package. And a shorty because he wanted to keep weight down for stock, but if it was mine, I would add some myself.

Ps. My rm car with the shorty came it at 1582g

rb6 plastic wide hangers, are they both improved or just the front hanger? (rf2 front hanger looks beefier than the old one). I cant tell the difference between the rear hanger.

thanks,
Rocky

Ryan,

"fastwon" on this thread has been playing around with mid motor on clay and looks like he has had some success. I think he mounted his shortie sideways and to the rear to gain rear traction. There are some pics on petit rc.
