I would personally call Kelly up and order a kit (but then again i race with him )

so a heads up I spoke with Lunsford today and they are in a process of putting a ball stud kit together for the rb6. They are making a smaller ballstud for the steering rack. They said some complained of bump steer. Eta couple of weeks

Bumpsteer is controlled on the steering block. The studs on the steering rack control ackerman. The lunsford ballstuds (the normal ones from the rb5), are the same height as factory... fyi.

Liverc said the same but didn't name specific drivers. They said a lot of Kyosho and Losi drivers have been testing mid-mount.

The aluminum replacement of the wide set is KYOUM514GM and KYOUM515GM

The aluminum replacement of the narrow set is KYOUM511GM and KYOUM512GM

The RF2 set or wide has been on backorder for ever.

Just so you know, they work in pairs. RF front and rear, or RF2 front and rear only.. it sounds like you have a RF2 rear block and RF front block. RF is a narrower track width and RF2 is wide track width. I prefer the RF narrow blocks, STRC sells them also a bit cheaper than Kyosho sells them for, but they only make narrow blocks. Good luck

There are 2 RF2 (fronts) in the kit, one has a thin sidewall which breaks and you aren't supposed to use and one has a thicker sidewall which is much stronger.

Check your parts
