Rear Shock Leaking! UPDATE

[jboult]

Bilstein HD shocks with M033 springs for me, also on a Targa.

Got to admit it’s a great combination on track, but too firm for the potholed roads around here. I’d look for more progressive shocks if I did it again.

From memory some people have been happy with the Koni FSD option on standard or ‘sporty’ springs.

After a great day at Swindon 993 Seminar and a great drive home I noticed a patch of oil from the NS Rear. After sticking my head under I could see a drip coming from the bottom of the shock, cleaned it up and checked again today and its dripping again
I'm still on original suspension
Why did it wait till after the seminar!
Now I have a Targa and wondered what people have replaced there's with
My car is going into Swindon for its Service and Windscreen tomorrow so just trying to prepare my self

Thanks

You're probably still using the original Monroe suspension - my understanding is that they are not up to much after 50k.

I went for KW Variant 3 coil-over suspension with RS configuration.

As John says, you need to be careful with a targa, the Koni's are probably your best bet, not called FSD's anymore, they are Koni SAS now

 

[Graham-S]

Thanks for that, I know I need to be careful as a Targa hence asking here. If only they had started leaking before the 993 Seminar then I could have fired lots of questions at them then!

Has anyone tried the new Classic re designed shocks from the new classic Porsche selection?

Konis on mine, part of a refurb by Centre Gravity (best place to go) a few years ago.

Went for Konis as Bilstein reputed to be stiffer - they are great, with compliant ride (with 18" hollows + M033 as originally[]).

With Chris setting this up, you will be pleased with the difference. Even at 160k+[]

Your 993 looked a bit high at the back when you passed me after the seminar, Graham.

 

[Graham-S]

There are no Bilstein HD anymore they all start with B's now!

Do I need to replace a 4 or just the rears? Should I do Springs and shocks?

All these questions just after the Tech Seminar!!

Will see what Swindon find on the inspection tomorrow before the service incase there are other things wrong that I haven't noticed and then I'll give you a shout

B6 and B8 are different, B6 (the old HD) are standard height. B8 are shorter and are great if you are going to lower the car. When you lower a car with M033 springs or the like you will stiffen it up as there isnt the length of travel there was before.

Good advise to do all 4, springs can be re-used if you're happy with them, they dont really degrade on 993's.

The Porsche Classic are Bilstein made, apparently slightly different spec to Bilstein own, and over twice the price!

i replaced mine last year after 58k

i went for B6`s its a good change new bushes

its was worth doing.

 

[Graham-S]

Has anyone used these new Koni active dampers?

https://www.koniuk.co.uk/cars/special-active-dampers/special-active

Gert @ Carnewal has them on his list for 993's and Chris @ Center Gravity also recommended them too

Had front bushes done a few years ago now as they were shot

Thanks

I have them on my 993, Graham (they are as per FSD)... sorted by Chris[]

 

[Graham-S]

Did you have all 4 Changed Paul? You very happy with them?

Did Chris change any other bits of the suspension at the same time eg top mounts etc

Chris isn't free till Mid June and I go to Isle of Man in May with PCGB and need to sort before then as I do notice the rear not damping very well on the bumps now as still leaking as don't fancy doing high speeds on the island like that!

Chris put all 4 on for me / plus a couple of bushes and rear arms - don’t recall all, but for a (then) 145k mile car, there was very little needed...didn’t need top mounts - very happy with all he did. Springs are fine originals, great geometry set-up and corner weighted. If you want any further detail info, pm me.

Yes, he is very busy, but worth the wait in my opinion...[]

UPDATE!

Just got back from the Isle of Man and she handles very well now. Little stiffer from the old 23 years old shocks but handles well at 120mph!

So I went with the Koni active dampers all round and also replaced all 4 top mounts at the same time

When the rears were being removed the drop links decided they didn't want to leave the old shocks so they also were replaced

Springs were retained on advice here and others

I bought the dampers from Design 911 (£740) and had James at JGC Porsche fit them + supply & fit the Drop Links (£460) then due to the short timescale for the Isle of Man I had to go to Reading OPC for the Geo (£464)

Swindon & Silverstone were fully booked till mid June and Centre Gravity too. I was on their cancellation list but nothing came up

I have the good old shocks and top mounts if anyone needs them
