    20mm or 26mm shock pads?

    RealOEM lists 20 and 26mm shock pads. Which ones would be necessary for H&R Sport/Lowering springs?

    you're talking bump stops right?

    do you have bilstein's sports for those springs? they come with internal bumpers, no need for anything else.

    that said, a few years ago i started playing with various bump stops using them as helper springs and was pleasantly surprised at how well it removed what understeer i had left.

    I didnt know the sports had internal bumpers, but I was talking about the pads that sandwich the spring.

    I guess Damper ring is what they are called.

    26mm will raise the car ride height 12mm over the 20mm ones.

    Sweet - this is why bump stops come in so many colors!

    Thanks guys, makes sense. Is it the same pad top and bottom as well? RealOEM seems to say so.

    Finally... anyone know if the rubber mounting needs to be replaced? Im assuming if its cracking it has to go.

    Let me know if I should consider anything else.

    Friend once told me "if you're in there and it's apart - do it all now"

    spring rubber on mine are the same shape top and bottom.

    Question are the new springs open ended like the stock or closed like aftermarket flat ground springs?

    I am assuming the ends look like the stock springs.

    The open 'rings' are interchangeable. They are however, kind of a bitch to find. Let me know if you do, I need a full set myself that doesn't cost an arm and a leg

    I may be misunderstanding here, but H&R springs look to be open, at least without load and from pictures online.
