964 C4. Which suspension upgrade?

[Encantada]

Offer still stands if you are near Colchester, have a look at mine.

Billies with H&R green, I did a write up some years ago that might be useful, it's on Rennlist somewhere. Under Warmfuzzies...or 964Kevin.

Thanks Kevin. I appreciate it. If only I had the time.

Another for bilstien B6 and HR (now purple but the same as the old greens)buy from Gert at Carnewal (third off uk price). B6 have threaded bodies so you can set the height.

Had FSDs on another car, a bit hit and miss if you ask me, they try to predict high and low speed damping, but just end up as a compromise. No height adjustment.

Get a strut brace for the Targa the DO make a big difference to the stiffness - ultra racing ally one is the best/stiffest £130 off the bay.

Try to get someone with a C2 to swap their rear ARB with you - great for both cars and free!

get the front wishbone bushes and top mounts changed if they are original, will tighten up the front no end. Play about with tyre pressures, it can make a big difference and it's free.

Hope this helps,

Cheers

edit to add - the rear shock turrets are different on early cars, make sure you order the right set, also not all after market shocks do an early car version.

Thanks for that. Mine is a 1990 car. So, it's early.

[Encantada]

Blib, 90 reg or my, they differ somewhat. An 89 my may be registered as a 90, but be earlier fittings, huge amount of information on rennlist for that.

Loved my 964 on standard factory suspension. All in good knick though not knackered like many are if still original. Ride height looks high so not so cool but 40K miles as a daily and I wouldn't have changed it as it was one of the nicest driving 911s I have ever had.

Sorry to labour this point. But a strut brace does NOT improve the chassis torsional rigidity at all as some of you are implying, it just improves the front camber stiffness. Doesn't matter whether it's a Targa, Coupe or Convertible in this respect. It does exactly the same thing for all variants. Improved camber stiffness is a good thing, but you would only notice if you were seriously loading up the front by cornering on the limit i.e. on track.

So save your £130 or whatever they cost, or at least try one before you buy. Placebo effect might be worth the money

I have

Blistein shocks and h&r green springs.

Made a huge difference to standard while not being two harsh.


You may also want to consider wevo engine mounts. Cheap. Very easy DIY.


Yes you should think about roll bars on a c4

I would say a must have is a thicker anti roll bar at the back. I used a c2 one iirc

With those two mods and geo set up turn in/ under steer was much improved.

Ride height was set to 5mm above rs or it might have been 10

The saga continues. I was about to buy a Bilstein/B&W setup when the chap who is refurbing a set of Eta Beta Krones for the car suggested KW V1 coilovers. He then mentioned several owners who had actually switched from B6s to KWs and preferred the latter.

Am I right to assume that the KWs give a firmer ride than the Bilsteins? I'm not a driving god (any longer). I'm not going to throw the car around unduly. I just want a better ride than the knackered original shocks. I imagine that the KWs will be a bit too firm for me.

Thanks.

[Alpinestars]

I've recently fitted KW1s on mine. The ride is quite a bit harder than the standard set up. But I do have the car sitting a lot lower which would make it harder. I don't think it would be particularly pleasant on poor road surfaces/B roads.

[Blib]

Thanks for that, Alpinestars. I think I'll go with the B6s.

I ran B6's and H&R springs on my C2 for a couple of years, set at RS+10,standard roll bars, brilliant blend of comfort and response, wished I'd never sold it!

Please post your findings/thoughts once you've had chance to assess the new set up.

Wheel sizes make a difference too, on 17's mine with B6 and H&R green is ok. On the 18's it's very firm. Bridgestone tyres are also known for very stiff sidewalls which probably makes life more interesting still.

Passing Colchester, I'll take you for a spin.

The Krones are 18s. I'll be fitting them with Continentals. Here's an identical set up, wheel wise, fitted to my car. Voodoo Motorsport had a finished set of wheel which we stuck on to my car to see how they looked. We didn't bother with the wheel centres.

Agreed, mine's on 18s as well.

My wheels are done and I pick them up today. I finally plumped for the B6, H&R setup which I bought from Carnewal in Belgium. The weak Euro made them a steal. Here's the wheels.

^^^^ look amazing - let us know how you get on with new set up. I'm on stock suspension which is beautifully compliant but the ride height at the front looks a tad high. Would a set of springs ruin the ride?

[Alpinestars]

Love those wheels, please put some pictures up when they're fitted.
