Hello everyone, Im new to the forum and this is my first post (but not my first Mercedes).
I've just bought a 1995 R129 500SL. The car has been lowered and huge wheels (18") put on. I don't like the car so low or so hard so am trying to put it back to standard. I've just bought 4 original wheels and tyres but I need to know what studs to use. The thread is 12x1.5mm. How long should they be and/or how much thread should protrude into the hub?
Also, where can I get 4 standard coil springs?

Thanks for any help.
