Just another thing going ..... (repair dampers or replace the whole lot??)

Just as I spent a significant amount on brake refresh (discs/pads/997 GT3 master), I had the car looked at for a ugly knock over bumps/holes, and one of my ohlins dampers has shaft play.... No leak or anything, but there is play which can be felt when car is up in the air, rocking the wheel along the vertical axis. For now, I'm going to turn the volume up when driving in town, but this will need sorting. Ohlin suggested some uk repair center which quoted 300+VAT to repair each damper. They're 10 years old, wouldn't i be better off going for a more soft setup like Billstein P8's with some eibach springs? What would you do, is my question... 1. repair 1 damper and live with the rest hoping they won't go soon 2. replce the lot with P8's+eibach -30mm kit 3. ignore till it pops

Billstein B4 with Eibach springs and thicker H&R anti-roll bars, the latter is for handling and the former for ride comfort

why b4 and not b6 or b8?

options B4 is like for like B6 is sports B8 is shorter and sports softer ride, B4 is the an option and the thicker ARB ensure you have better roll control, as opposed to using stiffer springs which have the unfortunate side effect of a harder ride speak to someone like Centre of Gravity on options

ok - thanks!

I have a 997.2 Cabrio. Replaced my dampers which were original Porsche PASM and fitted the B4’s with PASM along with a DSC controller and the car is utterly transformed. For the better, I would add

Have you not previously serviced them in 10 years? Although I don't comply with the specified Ohlin service interval, the fronts in particular take a lot of 'abuse' and are likely to need attention every couple of years of road driving. Adjusting each corner one click firmer might give you a bit more longevity/piece of mind while you consider options Note: it'll take a few days for the adjustment to have an effect and it'll only reduce things (although it can be noticeably) rather than cure

Nope, I haven't. To be honest, in the 10 years, the car has seen about 11k miles in total, so not a whole lot - but certainly more in the last 3 when the knocking has happened. I hold my hands up for not servicing them sooner, but to be honest it's not a setup i would've chosen for a daily as it is really harsh.

ditch the Ohlins get a softer set up that embraces the uk roads and gets you out in the car more you can sell the set on so there is 'some' funds to make back

Does this look right? Do I need to buy anything else? (bump stops / shock boots?)

looks right but remember when you take your suspension apart, how much of the housing can be reused, as you might need various parts that form the suspension, or you might be fine i.e. bump stops, dust covers, top mounts Dedicated to your Porsche needs Design 911 supply car parts, spares and accessories, to both retail and to the trade.

Our car product and accessory range includes brakes, exhausts, tyres, wheels and panels and interiors. #Porsche #ServiceCentre #Essex www.design911.com If you do go for the B4, if you are using H&R springs you might find the spring is too lose under under load. Bilstein do an M030 and standard front damper, I would guess the m030 one is slightly shorter to account for the shorter springs on the M030 cars, so it isn't loose. But not 100% sure? The rear M030 dampers are too firm imho. Nasty things. I ran standard ones after I fitted the M030 ones on my C4, much nicer, springs were fine on them. The B4 on the C4 front is the same damper m030 or not. I found it too soft if anything. I see the Koni is now cheaper than the B4, absolute no brainer to go with them. Amazing ride and with the H&R springs works so well. I have converted to RWD and used FWD uprights so I will be fitting those Konis myself shortly.

crikey, so what I'm hearing I might have to add approx £650 for other bits! Maybe I should get the ohlins rebuilt

Have you not kept the original dampers? There is a lot of fitting hardware on them.

the car came equipped with the Ohlins kit, I only have whatever's on them I might reconsider rebuilding all 4 to give them a new lease of life.
