BLBound and others - Here are some pics of the RX8 under the belt.
Had to dremel the cage and the rear chassis brace to clear the RX8's fins and rear solder post.
Paired the RX8 with a 1410 and running inline saddle packs. Chassis has 3.5oz of added weight.
Don't mind the positioning of the packs. I messed up a bit on lining up the countersunk holes - lol.

Car weight - no body
FL 580g - FR 581g
RL 709g - RR 707g

Ran the Saddles before up front (Left/Right).
Balance was nowhere this close.

btw - running the pin mod, clutch basket (HT/Reg/HT) and overdrive front pulley - Night and day difference
