What are the symptoms for worn bushings? How can you tell if you need them?

Regards, J.G. Neteler I had all rubber bushes replaced with ball joints and found the car far more precise and reassuring to drive. Then you could really lean on the car until the tyres would gradually run out of grip. An aside: noise levels did not increase with the installation of the ball joints. Did the same with my RS - and love it! :burnout: Steering control arm bushes can also wear. You notice it when the car needs two lanes during breaking. Go for the harder and more precise RS control arms. |
"Go for the harder and more precise RS control arms."
Control arms = wishbones or a-frames yes? If so, the RS were no good for me, the rubbers split within 2 years/ 20K miles. Maybe that's a long time by some, but I was pretty p*ssed at having to spend £800 again! Now I have had fitted the Powerflex poly bushes and they feel very good and expect them to last longer than the Porsche RS ones. |

I think Anatol talks about the steering forks, the first joint from the steering rack. they get really sloppy of age. I agree with Anatol, this is an upgrade worth doing and also un-expensive. I could bend my old ones how I wanted with my hands, the new fork was almost impossible to bend. |
I'm a little slow Thomas. What part are you talking about? Part 3 in the last picture?

Number 3 in the last pic. The one that sists between the steering rack and the tie-rod. I think you guys call it a steering fork /tie rod fork or something.
the C2 version is the softest, the C4/RS/Turbo uses the same and are a little stiffer, and finally there's a Cup-version which is the stiffest. But the Cup-version is much more expensive (and not worth the money). They are all made with a rubber bushing and it goes really soft from age so even a new C2 fork will feel stiff compared to an old one. They are all the same except for the stiffer rubber so you can fit which one you want. I'm not sure but I think I paid maybe 110 USD for a pair. |

On my C2 the servo-assisted steering rack had been leaking all its life with me. Actually, I replaced the rack two months before selling the car... :banghead::banghead:
The oil from the steering rack had been dripping onto the "tie rod" all the time, softening the rubber in the bushing to the extent that I really needed two lanes for high speed breaking. The difference with new tie rods was magic! |

The RS also has a thick washer built into the bushing package to eliminate motion, are you going to have this in your design?

a) Equivalent stiffness to RS, which ultimately may be acceptable as an alternative to the RS arm for racing. |
Any news on these yet?

Thanks for asking, I have not forgotten, it's just that with current workloads I have been struggling to finish difficult projects in the workshop and keep the pressure up on my suppliers. In this case they are also at the other end of the country so it's not as if I could call in to chase them, but with a bit of luck I'll find the time to call them in the next few days and give you all an update.
|
Just adding that I'd obviously also be interested in one or more sets for my Cup (should we also be able to get PCA to approve them as a replacement part).
|
Interested in a set.
