just got an eclipse 4 to run at amain new track with the crc black carpet. i have a few questions about the gt class on the hub part u4975 rh washer carrier. is that hub for a diff or can u use it on the spool as well. if u use the narrow gt contact tires on a 12th scale does that bring the track width to 165 to run any gt body. does anyone sell the scott jake rubber tires without using paypal. i got the acura body and was wondering if the foam bumper off the atom would fit or are people modifying some other foam. the kit i got had a few issues with missing parts and i,m not sure if the bumper i got is supposed to be countersunk on the bottom where the body posts goes. not sure if i have the right countersink to do it myself or if i should just use a panhead screw instead.
