911 (964 model) as if it were a new car

I picked up the keys and headed home. I drove a few dozen meters on Route 43 in front of the store and found the "Wow, not even close!'. I couldn't help but say it out loud. I can already see how round the tires are. I have never felt such a rolling feeling of tires from this car.

New front shocks

It is smooth.The sensation is about 20-30% more than before. Even in rough areas and over manholes, the "thumping and rattling" sound is almost non-existent.

It used to sound like an aircraft passing through bad airflow on rough terrain, although the impact itself is not so noticeable, but it has become much quieter. You can hear it from the rear if you are aware of it, but from the front it is virtually non-existent.At any rate, the front ground feel and smoothness are outstanding.Pitching was considerably reduced, and there was much less up and down movement of the eyes when driving.

NVH is generally quite restrained andAt a stroke, the 964 became a comfortable car.

The effect is also felt here when starting from a stoplight and during acceleration for overtaking.Response delay to gas pedal operation is much improved and better.It is. Probably thanks to the replacement of engine mounts, Tiptro mounts, etc.

The latest water-cooled Porsche has a function called PADM (Porsche Dynamic Engine Mount), which hardens or softens the mounts depending on the driving mode. This gives the impression of a crisp, muscular car when the car is in sport mode, and it is similar to the impression one gets when the car is in sport mode.

Movement as if the car were lighter and less body fat.It is.

As you can imagine, they didn't go straight home.We immediately went to Ashiari and then to Sundabruk rink for a test run.It is. Points that were not clear in the city gradually became apparent.

First.Easy to drive around corners!It is quite easy to drive. Until now, it would not turn unless I drove true to the RR basics of letting off the gas pedal, applying front load to turn, and opening the gas pedal earlier to get traction to turn, but even if I cut corners a bit on that, it turns perfectly.

And it turns smoothly. Of course, it's not as easy-driving as the latest water-cooled Porsche, but still, this would be much easier to drive.

I also felt a change in behavior in the middle of the corner.Perhaps because of the stronger front ground contact, the car tried to go in the middle of the corner with a gulp, gulp, gulp.This is a feeling I often get with GT3, and I've come to feel something similar to it with 964.

The Tiptronic shifting is also very small. Until now, when the accelerator was released from high rpm in 2nd gear hold, there was a slight backlash and a slight sensation of sudden engine braking, but this has been reduced considerably. I can't tell for sure if this is thanks to the replacement of the tiptronic mounts.I bet the ATs are looking good too.It seems.

The front end of the car was raised quite a bit. It seems that this is still the lowest setting.

In the straight line of the Ashiari Tunnel, theThe improved straight-line stability is clearly visible.It runs straight and crisp. It has not been so bad in the past, but here, too, the stability seems to have increased by 10-20%. It is the kind of stability that makes you want to try long-distance cruising.

Climbing up from the Arima side at Ashiu Esses, this is where RRs, especially air-cooled Porsches, have a hard time.A steep winding road with narrow tight corners.When I first bought this 964, I drove it here without a second thought.How it wouldn't bend! I remember being amazed.When I drove there in the reborn 964, it was as if all the hard work I had done up to that point was for naught.

Naturally, since it is RR, load transfer is important, but even so, the ease of driving was totally different. I felt more relaxed and able to run.

At the Sundabrückring, we will try to focus on slightly rougher surfaces and mid-speed corners.As expected, there is little vertical movement of the front.Naturally, the ride quality is not as good as that of today's water-cooled Porsches, but it is still quite easy to see that the legs are moving well, and the car is flat and pleasant to drive.

Originally, the rear of the 911 is firmer because of its heavier rear end, but the front end is lighter and has softer legs. Therefore, the ride is said to be relatively comfortable for a full-fledged sports car, and this was well understood during this refresh.

On the way home, I examine it again on the familiar road to my house. The difference between the two is clear.After all, the improvement in ride quality and ease of driving are considerably different.Imagining that 28 years ago, in 1992, this 911 was running like this, it was somewhat like experiencing the past in a time machine.

Although it cost a good deal of money this time, I am really glad we did it. If we had not done it, we would have almost spent our lives without knowing the true 964.If you are a classic Porsche owner and your budget allows, I recommend freshening up the suspension.The driver's satisfaction is high, but above all, the car itself seems lively and happy. The driver himself is highly satisfied, but above all, the car itself seems to be lively and happy.

The next step is to plan a body refresh. We are still a long way from getting as close to a new car as possible.

    I read it with a phase of "yes, yes....

    I have been driving a 964C2MT/1990 for about 6 years. 82000km when I bought it, now 106790km.
    Around the 90,000 kmm mark, the shocks were changed from damaged, ride-height-adjusted, runabout specs to near-normal Bilstein and Eibach shocks, and the ride became dramatically easier.
    Around 10 kmm, we replaced the hub bearings and upgraded the brake rotors and calipers.
    The engine was OH'd around 50,000 kmm and is in great shape.
    Having never driven another 964, I imagine this is how it must have been in the past.

    Now I would like to refresh the mount and bushing relationship.

      Mr. Kozzie521.
      Thank you for visiting my blog!

      I see you have over 100,000 kilometers!
      I know it's a lot of work to be around for upgrades and maintenance, but...
      It is also amazing that when well maintained, the car still runs as strong as it did when it was new.

      I would be happy to learn more about the maintenance and upkeep of the 964.
      Thank you for your continued support.

    This is my first time to respond.
    I am on the roof, not the reef. w
    The husband told me that he was going to refresh the suspension of his 964 in Ashiari the other day.
    I'm glad it feels the way it did when it was a new car. I also maintain two air-cooled Porsches, a RUF RCT and a 964C2, and I think the suspension is important, especially for RR Porsches. 964s often consult me about the front fluffing at high speeds, the rear coming out quickly in corners, and strong understeer, but if properly maintained, such things do not happen. If the car is properly maintained, there is no such problem, and most of the time it is due to the loss of damper, bad alignment, or ride height balance between front and rear. I have owned RUF for 12 years, and during that time, I have replaced the suspension bushings once, overhauled the front dampers once, overhauled the rear dampers twice, and adjusted the alignment 4 times. The 964C2 is now 7 years old, and although the suspension was freshened up 2 years before I bought it, the alignment has been adjusted twice. The rear damper is especially prone to sagging due to the heat of the engine and the stress of the engine weight.
    I look forward to further comments from your husband.

      Thank you for always taking care of my husband in Ashiu.

      >I'm on the roof, not the reef. w
      I really don't know much about cars, and I first learned about roofs when my husband took me for a ride before;

      >If properly maintained, this is not the case, and most of the time it is due to damper disconnection, poor alignment, or front/rear ride height balance.
      I see! Cars are so deep...
      For air-cooling, maintenance and servicing are really important.

      My husband has been doing some maintenance and repairs, but the car seems to have really improved compared to when it was first delivered to us.
      Lately, I've been saying to myself, "964, I'm feeling good.
      He said.

      I'm going to be standing by to see how you feel about it all and how it will change!
      Thank you for your continued support.

    We are currently waiting for delivery of the 964.
    This is my first time to use air-cooling, so I am learning in advance by reading.
    Since we purchased the car in another prefecture, it was helpful as a maintenance place after delivery.
    I look forward to more air-cooling related articles in the future.

    • Mina.Mina.

      TARO.
      964, almost there!
      Regarding air-cooling, my husband seems to be getting closer and closer to a new car in the future.
      I will ask him to write another article.
      Thank you for your continued support!

    Hello.

    Good job on the 964 suspension refresh. No matter how good the quality of the used car is, it is over a quarter of a century old, so putting new parts back in will drastically change the car. You may have felt it after the refresh, but the stock 964 is very comfortable to drive. It is hard to believe that it is a sports car.

    I am a stickler for the original, but the stock ride height of my 964 was too high and not cool, so when I refreshed the suspension about 7 years ago, I decided to use Bilstein's PSS-10 (now B16?). I set the ride height down modestly by 25mm, and the ride comfort was set to the softest of the 10 levels for enjoyable city driving.

    Looking forward to another air-cooled report!

      964, a refresh would make the ride that much better!
      I have yet to ride it after the refresh and would love to do so again.

      In a word, 964 (911).
      I thought there are so many different settings and ways to ride.
      Sports cars are very deep...

      My husband went touring in his 964 the other day, so I'm sure I'll blog about it again ^^.
      Thank you for your continued support.

    Hello~ (^. ^)

    This past Sunday in Ashiari, the husband also said....

    This is an old car, so this kind of refreshment works well.

    My son is missing the building shocks, too, and I'd like to replace them.
    But the height of the car is going up. lol

      >I was in Ashiari this past Sunday, and your husband also mentioned it.
      Really! It's like a different car when you refresh it, I wonder if it was like this when it was a new car back then...
      I thought it was also profound to ride in my imagination as I listened to the conversation.

      Even a slight increase in ride height can change the atmosphere of a car!

    It is wonderful. I want to do it too, but I can't get the parts.

    If you don't mind, could you please tell me where you took the parts?

    I look forward to working with you.

      Hello.
      In my case, when I usually ordered genuine Porsche parts at the shop, it arrived immediately, but is it out of stock now? ??
      There were some parts ordered from my home country, but I think it took about two weeks.
      The shop I asked for was in KobeB-ForceMr. is.
