Want to know what the difference between the 4matic and rwd conversion kit is? Can I use the 4matic kit on the rwd car it looks like it will fit but don’t know what’s the difference is ? Any insight will help please

Ok I'll bite. Why do you want to use 4matic struts on a RWD? Also why do you even need a conversion kit? RWD struts, springs and mounts are widely available from many different suppliers.

I'm a bit weird in that I kind of trust the designers employed by Mercedes Benz to know what they're doing. Sure, there will always be a compromise between ultimate racing performance and street driving. But unless you're racing, why would you presume to know more than Mercedes Benz engineers?

I have a stock-standard E500 W211 and apart from upgrading the Comand Head Unit, which they quite arrogantly no longer provide map updates for - I love it.

He needs a conversion kit because he wants to place traditional rear springs in place of the bags, along with traditional shock absorbers in place of the electronic MB units. Strutmaster sells a "kit" to do this.

Okay, thanks - still not sure why.

Because the airmatic is extremely problematic on these cars. His rear bags have likely failed and he doesnt want to deal with it. Just taking a guess here.

Aah, thanks - now I capsih, sorry.

Haven't had an issue yet but mine has only done 80,000km - what sort of problems - or obviously a link to a thread would be easier than listing them all!

Just do a quick search for "airmatic" in this forum and you will get pages upon pages.

So just buy E320 coil springs. You don't need a conversion kit.

You are missing the point. Their "kit" comes with everything in one package. Its about convenience. And the guy didnt ask about e320 coil springs, he asked about the strutmaster kit....

You're missing the point. The kit is not built to Mercedes standards. They made some very big compromises in order to make their kit work with the airmatic control arms. There are many unhappy customers. Same goes for arnot's kit.
