Explain the 300 dollar shock to me, What the... Options

[emerygt350]

An insert for 275? What and why? Is it just rarity? Some strange one off design that no other car uses?

Well, the car has had a 5 bolt conversion. So those might be 911 A arms, don’t know how to tell the difference.

How was the conversion done. With redrilled rotors or a switch to 911 struts? Does it have 914 brake calipers or 911.

No it’s full 911 brakes with vented rotors on the front, so I guess the struts are also 911. So maybe the stiffness of the ride is coming not just from the shocks, but also the spring rate… When I get the car back up on the lift, I will try to see what diameter they are. Does that mean I need to be looking for 911 inserts for those? Is there a difference?

Again, for the rear springs no idea what they are, they look newish, black paint perfect, no rust, but no markings I could find either.

@wonkipop - I tacked my request to the end of this thread instead of starting a new one because it mentioned the Boge replacements made by AA. So the title is a bit OT relative to my issue, personally money spent is not an issue, getting a better ride is.

was addressing OP (emery350gt) not you chmillman (IMG:style_emoticons/default/biggrin.gif) sorry for confusion.

for emerygt350's interest i found my receipts for the billsteins back at end of 2019.
B6 bills.
front pair $847 AUD
rear pair $770 AUD
googling the AUD back then - 1.00AUD = 0.72 USD
cost for pair of fronts $609.00 USD. or 300 each.

same price as now by the looks of it. zero inflation?

@chmillman - back in 2019 you could not get boges or boge replicas from mr atlanta.
choice was between billsteines and konis. don't think even cheapos were an option for me in north antarctica. not even available.

truthfully i would not have minded boges again (if they existed) as the car has factory sway bars. allow for the softer shocks in a kind of comfort/performance compromise.
most of the time the B6 are not too bad comfort wise.
but definitely a bit stiffer.

re your springs. not sure 100 lb springs are original spec.
others here know more.
i have a vague recollection the originals were in the 50-60 ib range.
there is some figure in the factory manual which is in kp.
seem to remember something about three different strengths.
but can't remember how that worked. someone here would know.
i reused my original springs. seems to be working ok with the B6s i put in 5 years back.
