Is there anybody that has ran their car at multiple tracks without drastically changing the setup. I've been thinking about getting one and plan on doing the jbrl next year, wobt have a lot of time to get the setup dialed into each and every track. I can throw my B4 down pretty much anywhere without changing much and it's good. Thanks!

Oh those are coming ... We are testing them right now and our new diff has better quality outdrives that will wear less and are less expensive

The K outdrives are 12 bucks for male and female. I will say that if the outdrives and shafts wear less, I think I would buy them.

Definitely interested on C-CVD's for the 6.

Diff looks good for sure but it could make sense to run the whole thing altogether (cvd and diff).

Anyway, awesome to see some MIP products for this car !

Hi everyone,

So far my RB6 has been amazing after 2 days of running non stop with some heavy crashes, I haven't broke anything yet. I bent one of the front turnbuckles and replaced it with the Lunsford titanium 1-5/8 kit part number 1066, it's a direct fit same size and length.



Thanks,

Has anyone played with running more caster than the 0s? My car has more initial steering than I would like.

What major difference do you notice when switching to the 4s?Our local fast guy said he switched to the 4 to tame his steering. Any can chime in the advantages and disadvantages switching to the 4

I am currently running 30/0 and the car is amazing. It tamed out the infield steering just a tad, and made it even more of a beast in the sweeper. I wanted to see what the extra kick-up would feel like. I have tried 25/0, 25/4, and 30/0... so far i like 30/0 the best.

I hadn't even thought about trying more kick up, good idea. I believe the kit has the option of running 2 degrees of caster, have you tried that? The car is really damn good for me right now, it's just too aggressive when the track dries out. Normally my home track is a damp clay with a solid medium traction level. Hot tires are pink gigabytes or m4 hole shots and soft or super soft rebars at least in my group.

Just ran the car tonight in an actual race and bam the car was awesome. I am really stoked to get the AVID pistons and try those out, hopefully it will calm down the rear end a little bit. My only complaint was my seemed to be a little bouncy, hopefully the next outing I will be able to tame it down a little.
