I recall that three months ago a client in the US said that he machined up a bolt with the same head detail as the original to overcome this.

We have not checked it out, but the only basic difference to this bolt is the K-Mac bolt has a machined flat the full length so that it can engage the inner steel bush to make and retain camber adjustments.

To simplify things I will check this out myself and see if we can include a bolt specially made for the convertible in future kits. I will contact you again within the next week.

I'll advise you when they are ready, anyway. K-Mac is determined that the adjustment for the rear end of these models needs to be on the lower arm, as extending the upper arm to reduce negative camber always closes the gap between the tire and the inner fender. With wider wheels and modern tires, this is not a good alternative.

Additionally, I believe that it's easier to set the alignment with the lower arm adjustment, saving time on the hoist at the alignment shop, while the toe adjuster is always going to be an improvement as it gives double the factory toe adjustment.

Not only that, but we make the claim that we can supply camber, caster and toe kits for every Mercedes Benz model since the late sixties, this convertible problem caught us off guard and we have to satisfy that claim!

Regards,

Kevin

Well, that's interesting. I told him I didn't want him to go through any trouble as there's several adjustable rear arms available for us and this was his reply:



Talk about customer service! Not to mention we exchanged these emails in a matter of a couple days and they're based in Australia. So any of you guys interested in a KMAC rear kit and have a convertible, a custom kit is in process. I've already asked Kevin concerning the ETA as I really need to start dialing in my front and rear alignment; I'll keep this thread updated if anyone cares. I'm not affiliated nor endorsing KMAC, just thought this was some good info.

I don't endorse adj. rear arms, MB camber bolts, or KMAC; again, just passing onto other cab owners who are looking for options.

KMAC is the only quality kit I happen to know of that can give a wide range of camber, caster, and toe adjustment. If you know of another kit/company that can do this AND supplies the said special bolt KMAC mentioned for the convertibles, please share.
