RPM gold II. Finally a runner...

[LowClassCC]

I've been out of the RC-10 game too long...

I've ran a worlds front-end back in the day, I believe it was made by RPM?

yes rpm made the worlds long arm conversion.

What brand rear bulkhead is that that you've got on your car? I see it allows the ues of the RC-10T shocktower...what are the advantages of that over the stock shocktower? Longer travel with the rear arms?

he has the rpm rear bulkhead made for the rc10t on it. using a 10t rear tower does change the geometry of the rear end a bit. some people say it works some say it dont. i personally cant drive good enough for it to make a difference so i can't give you my opinion on how well it works. now i do have my rc10 runner built with a 10t rear tower but the reason i used one is to lower the body on a cut chassis. so for me it's a looks thing.

Thanks Low. Might try another rear tower someday if my skills ever improve.

So is the consensus that the ceramic balls are too hard that have caused the grooving? Not too sure myself if an over tightened or loose diff would cause this?

Ceramic would be way harder on the Mohs scale for sure, prob a contributing factor. The stock washers and balls are just fine!

As far as the rear tower goes...the nearly vertical shock position causes a bunch of undesirable handling
as when the car rolls the rear shocks have no leverage on the arms at all- causing the rear to over rotate as
the chassis can't re center itself from left to right. There are other issues too, but that is the most prominent one.

Great looking car, awesome looking work shop! Looks surgical clean! Wonder if you have HEPA filters removing particulate from the air too!!!

I can attest to that...car looked awesome and was awful on the track. Between heats swapped in the stock rear tower and couldnt believe the difference.

May have to give the stock rear tower a try. Picked up one of jaydubs rear towers to try out.

Delete.

Gonna give this car another shakedown almost 1 year since it last ran at the track. Made all the changes suggested and has sat for awhile.

One thing I noticed while going over everything is that I have the wide GT front axles. Will the standard length front axles work with Jakes arms? Thought that was mentioned somewhere. It is pretty wide with the GT axles.

[JK Racing]

I didnt use wide GT arms with Jake's arms, I used standard, matched up to my B4 front just fine like that.

[askbob]

Cool. Tried to find Jakes arm thread with no luck. I'll try switching to standard length axles this evening. The wide axles could've been why it seemed twitchy last time out.

[Seabass]

Bob, run standard front axles with the B4 wheels. The arms were machined to the proper length without having to add the wide axles.
