Question for the collective.
My 86.5 was born with the sport suspension option.
Which my understanding is: stiffer factory springs and red Boges.

I took the reds off two years ago, they were pretty tired.
I have had black stock Boges on since.....meh.
I won't say they suck, just too soft.
I would like to get back to the factory sport option feel.

My assumption is you cannot rebuild a Boge shock, correct?
Also, after looking around, I've never seen new Boge reds for sale? Are they in production?
How close are the red Koni's?
I'm not quite ready to pull the trigger budget wise, but looking to get my ducks in a row...

Regards.

I thought Bilsteins were the sport suspension option...or was that a different year?

Mrmerlin

Roger sells them both Boge Reds and Bilstiens

Crumpler

I think at one point Bilsteins were used as the sport option, I want to say earlier in the production run, but not S3 MY's? One of the experts can correct me.

Stan, I hadn't asked Roger, that's good to know.
Roger, if you are watching this channel, what is the cost for Boge reds pray tell?


Here's a random question (and my prediction is that Rob will know this): what is the number of 86.5's with manual/LSD/sport suspension?

Koni's set on medium are going to give you a very close feeling to the Boge sport feeling with the ability to adjust them. Those are my choice.

Rob Edwards

The database is missing a bunch of cars (VIN range 1001- 3010, but there are only 1907 listed, so missing 103), but there are 68 5-speed LSD M474 cars.

Tom in Austin

928s to best of my knowledge only ever used one spring rate for all US cars. There are different "tolerance groups" that were designated by color markings on the coils to match up from side to side, but the spring rate was nominally the same.

So, "Sport Suspension" only meant different shocks like the Red Boges.

ROG100

Koni - internally adjustable are $750 for a set of 4
Bilsteins are $928 for a set of 4
Boge Reds are $1400 for a set of 4

A little off topic but regarding red shocks:I have red boge on my 92 GTS , but part # is 928 333 051 16 for rears(never checked PN on fronts)...are those shocks the real red boges or just "painted red" boges?(my car has not M474 option from factory).
never seen other 928 gts around here, so I cannot ckeck...

Crumpler

Just dug out from Monday morning rush and saw this. Thanks Rob, somehow I knew you could tell me .
That's interesting, I guess I should continue to take care of it...

Thanks Roger, I guess I will keep saving up. I should have just bought them the last time...

How do the Bilsteins compare to Boge Reds, in terms of performance and road feel?

the flyin' scotsman

Bilstiens can be rebuilt.........others?

I have Bilstiens on my S4......they perform great but somewhat harsh for everyday driving with Eibach springs.

The Forgotten On

That is most likely the springs, many people were having this issue. If you go to stock springs you will have a much better ride (Doc Brown's combo of choice).

You could also have the Bilsteins revalved, however with the non linear spring rate those springs have it would at best be a compromise.

Strosek Ultra

I have red Boge with progressive factory springs on the red car and Bilstein with Strosek springs (probably Eibach springs) on the blue car. The ride with Boge is softer and more comfortable but I prefer Bilstein which gives a better "performance feel".
