Is that longer arms? look same length .. I got the same/similar set up .. those r Proline bead loc .. very heavy ... (I took the metal ring off, much better .. )
Regular 12mm .. and lots of offset already .. (width almost longer then wheelbase .. ) and yes, they are DAMN heavy .. those rims are still plastic, but the "RING" is metal, just for look ... the Metal ring is heavier then the rim itself!! Dual servo (or upgraded servo) is a must!
I took the metal rings off .. but hassle .. so I just took off both front rings ..
Yeah... I got mine upgraded to dual servo... But then my other mini rally servo toasted, so I took one servo out to just subsidize ... Then I bought a mini servo back....and I don't know where I put the servo horn and parts....
